1
All power supply data is stored in the power supply inverter module's class information base (CIB) tables in the power supply.
This data is accessible directly via the power supply’s smart display (see the power supply’s technical manual for details).
The CIB tables are the source of the transponder’s data.
2
The DSM Series contains both SCTE-HMS Management Information Base (MIBs) and the proprietary Alpha MIB tables. The
SCTE-HMS MIBs are industry standard MIB tables that store power supply, battery and generator data from the CIB tables
(See Section 7.0, Data Management). The Alpha MIB contains all the data of the SCTE-HMS MIBs plus additional power
supply settings and values as well as DSM3 Series configuration values.
3
An external generator or additional power supplies may be connected through the COM (AlphaBus) port permitting
monitoring locally through the Ethernet connector or remotely via the Web page or SNMP-based Network Management
System.
4
Power supply and transponder parameters can be monitored and set locally using a personal computer and a standard
Ethernet cable.
5
The DSM3 Series transmits data via its cable modem directly over the Coax or Hybrid Fiber Coax network.
6
The Cable Modem Termination System (CMTS) is the bridge between the cable network and the TCP/IP network. The DSM3
Series’ cable modem communicates directly with the CMTS.
7
The Dynamic Host Control Protocol (DHCP) server needs to be provisioned with the DSM3’s cable modem RF MAC Address
and the MAC Address needs to be assigned a DOCSIS Configuration File.
8
The DOCSIS Configuration File and firmware files should be available in the Root Directory of the Trivial File Transfer
Protocol (TFTP) Server.
9
The Time of Day (TOD) Server provides the cable modem with the current date and time via the SNTP protocol.
10
A Network Management System (NMS) or MIB Browser allows remote monitoring of parameter values and changing of
settings in SNMP MIB tables. SCTE-HMS and Alpha MIBs must be installed in the browser. Alarms and traps can be set and
monitored.
11
The power supply and generator may be accessed remotely through the transponder's Web page by placing its IP address
into a standard Internet Web browser.
745-814-B8-001, Rev. A (08/2011)
2.0 Overview
2.2
Network Connectivity
The DSM3 Series cable modem must be recognized by the CMTS as a valid device to be assigned an IP
address from the DHCP server, to locate the TFTP and TOD servers and to communicate with the SNMP
management server (trap receiver).
Data from both the cable modem and power supply are accessed and managed through the modem’s
IP address on the secure private modem network. The transponder is not accessible from the public
Customer Premises Equipment (CPE) network. Consequently, the Network Management System (NMS)
that monitors the power supplies must have access to the same private modem network.
CMTS and system vendors use different security methods to insure network integrity, but common
considerations are:
2.3
•
MAC filtering may have to be modified to allow RF MAC registration of addresses starting with
00:90:EA - North American or 00:03:08 - Euro models.
•
For SNMP access, UDP ports 161 and 162 must not be blocked.
•
For TFTP access, port 69 must not be blocked.
•
For HTTP access, port 80 must not be blocked.
•
For SNTP access, port 37 must not be blocked.
•
Firewalls must allow TFTP, DHCP, SNMP and TOD communication to the cable modem.
•
If the address of the TFTP or TOD server is different than the DHCP server, the response from the
DHCP server must contain the TFTP and TOD addresses.
System Configuration and Installation
NOTE:
Before installation, read all of the “System Overview” Sections.
DSM3 Series installation and setup is comprised of three basic steps:
1. Configuring the Network: Provisioning the DHCP Server with the transponder’s MAC Address and
assigning it a DOCSIS Configuration File.
2. Setting Options: The DSM3 Series is designed for out-of-the-box, "plug and play" operation, but
non-default settings such as SNMP trap destination addresses may be required for the Network
Management System (NMS). SNMP trap addresses can be set automatically via the DOCSIS
Configuration File per RFC 4639, while DSM3 Series proprietary options may be set through type-11
TLV entries. The SCTE-HMS and Alpha MIBs may need to be compiled into a MIB browser before it
can be used to monitor or set transponder and power supply parameters.
3. Field Installation of the DSM3 Series into the power supply, connecting the battery sense wire
harnesses and verifying operation.
These steps can be performed independently of one another. However, configuring the network prior
to field installation will allow the installation to be verified while personnel are still on-site. Performing
field installation before network configuration and before the installation can be verified, might result in
additional field service calls to correct mistakes.
Carefully read the following section in order to understand the dependencies within the system before
performing system configuration or hardware installation.

3.1
Provisioning the DHCP Server with the MAC addresses
On the DHCP server, assign the cable modem’s RF MAC address with a DOCSIS Configuration File
to set modem communication options. (See Section 3.2 for instructions on how to create a DOCSIS
Configuration File).
The RF and CPE MAC addresses are located in two places on the DSM3 Series and on the packing slip,
see below.

3.2
The DOCSIS Configuration File
A cable modem’s DOCSIS Configuration File is a type-length-value (TLV) file that contains important
operational parameters as defined by the DOCSIS standards. It provides certain settings for the cable
modem. In addition to standard entries, settings in the DOCSIS Configuration File should include the
modem’s community strings and, if an upgrade is necessary, firmware upgrade parameters. Place the
configuration file in the TFTP root directory.
To build a DOCSIS Configuration File use a DOCSIS TLV editor program.
See the example Configuration File in Section 3.2.3.
NOTE:
The modem community strings should be set in the DOCSIS Configuration File. Failure to set
community strings will result in a less secure system. For automatically updating modem firmware
with the DOCSIS Configuration File, see Section 5.1.
3.2.1 Setting Modem Community Strings
Set the modem community strings with the DOCSIS Configuration File by including the following

NOTE:
DOCSIS configuration files vary from system to system. Take into consideration your company's policies, and
test the file on a local system prior to widescale deployment.
In previous versions of the DSM product line, an additional configuration file (also known as a Setup File)
could be used for distributing custom Alpha MIB settings to all DSMs on a network. This is still the case,
with the only difference being the name of the file, which for the DSM3 Series is atidoc03.cfg. It may be
used if preferred, but is not required.

3.2.4 Proprietary Configuration File ‘atidoc03.cfg’
The DSM3 Series will attempt to download a TLV-formatted file ‘atidoc03.cfg’ from the modem’s
provisioning TFTP server at startup and every 24 hours thereafter. The atidoc03.cfg proprietary
configuration file is optional and provides an alternative method to the modem’s DOCSIS
configuration file for deploying Alpha proprietary SNMP MIB parameters to field-installed DSM3 Series
transponders.
The atidoc03.cfg file should be used if the following conditions are true:
1. Non-default settings, such as SNMP Trap Destination Addresses need to be distributed to all
DSM3 Series transponders.
2. The operator does not desire to place Alpha-proprietary parameters into the modem’s DOCSIS
configuration file.
NOTE:
The recommended method for setting the SNMP trap address(es) is through the modem DOCSIS
configuration file (See section 3.2). Alpha-proprietary parameters may also be set through the modem’s
DOCSIS configuration file, eliminating the need for the atidoc03.cfg proprietary configuration file.
To build the atidoc03.cfg file, enter the desired SNMP OIDs and values from the Alpha MIB into a
TLV file as TLV type-11 entries using a TLV editor as TLV type-11 (See table 3-3). The DSM3 Series
proprietary configuration Setup file must be named “atidoc03.cfg” and placed in the root directory of
the TFTP server. DSM3 settings are updated according to values defined in this file at startup and
after every 24 hours of operation.
Sample atidoc03.cfg Entries:
SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.1 / 10.20.30.40
SNMP MIB Object (11) [Len = 24]: atiMgmtSnmpTrapAddress.2 / 10.20.30.50
SNMP MIB Object (11) [Len = 23]: atiMgmtSysTamperPolarity.0 / 1
3.2.5 Changing Default atidoc03.cfg Download Settings
By default the DSM3 Series will download the atidoc03.cfg file from the provisioning TFTP server
every 24 hours, but these settings can be adjusted per the tables below by placing the respective
SNMP varbinds into the modem’s DOCSIS configuration file.

4.0 Web Interface
Overview
The DSM3 Series power supply transponder provides an embedded Web server interface to allow
operations personnel the ability to connect locally or remotely via TCP/IP over Ethernet with a laptop/
computer to verify the status of common data points and to configure various operating parameters.
4.1
Local Web Server Access
The DSM3 Series transponder’s Ethernet port (comparable to the “Craft” port on some transponder
models) will typically be used as a local connection point allowing the user to connect directly to the
DSM3 Series Web server interface to verify/configure common communication parameters and view
power supply status and battery values. The Ethernet port on the DSM3 Series is a fully functional
standard Ethernet port, capable of providing all the functionality of any standard Ethernet connection.
To access the DSM3 Series transponder Web server locally utilizing a Web browser, follow the procedure
outlined below:
1. Connect a standard Ethernet cable (CAT5) between the DSM3 Series transponder Ethernet port (ETH)
and a laptop or computer’s network interface port.
2. Launch a Web browser.
3. Enter the transponder's default IP address (192.168.100.1) into the Web browser’s address field.
4. The transponder’s Web server home page will appear (Fig. 4-1). Note: For the DSM3 Series, this
may take up to 45 seconds when the transponder is initially powered up with no RF connection.

5.0 Upgrading Firmware
5.1
Upgrading DSM3 Series Modem Firmware
The firmware is upgraded using standard DOCSIS methods as defined in RFC4639.
There are two ways to upgrade the modem’s firmware: by directly setting the appropriate MIB parameters
in the docsDevSoftware branch, or by including the appropriate SNMP parameters and values in the
modem’s DOCSIS Configuration File, stored on the TFTP root directory.
Both methods are explained below.
5.1.1 Identifying the Modem and Obtaining Firmware Files
The cable modem firmware in the DSM3 Series requires its own firmware and manufacturer's
Code Verification Certificate (CVC file).
Contact Alpha Technologies to obtain the latest firmware and manufacturer's CVC files.

5.0 Upgrading Firmware
5.1.3 Upgrading Manually by Setting SNMP Parameters
1. Acquire the firmware and CVC files for your DSM3 Series from Alpha Technologies.
2. Import the CVC into the modem’s DOCSIS Configuration File (to create a Configuration File,
see Section 3.2).
3. Set the following MIB parameters using an SNMP MIB browser. For additional information
regarding the SNMP MIB parameters, refer to the table in Section 5.1.2., "Modem Firmware
Upgrade SNMP Parameters".
Parameter
Value
docsDevSwServer
IP Address of TFTP server
docsDevSwFilename

The firmware upgrade will begin immediately. Monitor the upgrade status with the
docsDevSwOperStatus MIB parameter, and verify the firmware version with the
docsDevSwCurrentVers MIB parameter (refer to Table 5-1, "Modem Firmware Upgrade SNMP
Parameters"). Once the firmware has been upgraded, the modem will automatically run the new
version.
5.1.4 Upgrading via the DOCSIS Configuration File
DSM3 Series firmware can be automatically upgraded using the DOCSIS Configuration File
by adding the following docsDevSoftware SNMP parameters and the manufacturer’s Code
Verification Certificate (CVC).

The firmware will be upgraded on the next reboot. Monitor the upgrade status with
the docsDevSwOperStatus MIB parameter, and verify the firmware version with the
docsDevSwCurrentVers MIB parameter (refer to Table 5-1, "Modem Firmware Upgrade SNMP
Parameters"). Once the firmware has been upgraded, the modem will automatically run the new
version.

6.0 Data Management
6.1
SCTE-HMS MIBs
The DSM3 Series remotely reports power supply data and alarms using the Simple Network Management
Protocol (SNMP) over the DOCSIS (Data Over Cable Service Interface Specification) communications standard.
The DSM3 Series typically reports into a centralized Network Management System (NMS) through a standard
collection of data access points referred to as the SCTE-HMS Management Information Bases (MIBs). The NMS
polls the DSM3 Series for power supply data with the option of having the DSM3 Series send SNMP traps in the
event that an alarm condition occurs. In addition to the SCTE-HMS MIBs, the DSM3 Series also supports the
Alpha proprietary SNMP MIBs, which allows direct access to the power supply as well as the ability to change
transponder settings.
The following MIB (Management Information Base) files are required for the NMS or SNMP Manager to
collect data from the transponders. These files can be found on the Society of Cable Telecommunications
Engineers (SCTE) Web site www.scte.org. There are dependencies between MIB files so they should be
compiled in the order listed below:

SCTE-HMS MIB Alarms
6.2.1 SCTE-HMS Configurable Alarms
The HMS discrete and analog alarms provide the capability to monitor and alarm various
power supply and environmental conditions and measurements. The alarms in the SCTEHMS propertyTable and the discretePropertyTable can be defined and set to provide a custom
monitoring system.
The following section provides an example and detailed information on how to set values, enable
or disable alarms in the MIB tables. For ease of reference they are in this sequence:
• An example of how set a temperature alarm
• A table to help convert the desired reported alarm states to hexadecimal for setting the MIB
• Commonly monitored parameters and recommended values
Example:
The alarms for psTemperature below are set so that the normal temperature range is from
30°C to 45°C. If the temperature rises above 45°C, a casHI alarm will be sent to the alarmTable.
Anything over 50°C is considered a critical condition and will generate a casHIHI alarm. If the
temperature falls below the normal level of 30 degrees and casLO will be generated and if it
continues to drop below 0, a casLOLO will be generated. The temperature must rise above the
LOLO limit plus the deadband value of 3°C before the casLOLO alarm will change to a casLO.
The alarmEnable field is set to 0F Hex to monitor and alarm for all conditions.

6.2.2 SNMP Traps
Use of SNMP Traps allow the network manager to set conditions (alarms) under which the device
(or devices) autonomously report to the headend the existence of the pre-configured event. The
type of event determines the level of action to be taken.
1. Verify the IP address of the trap destination server(s) has been configured.
If the trap destination server requires configuration, refer to Section 3.2.2, "Setting SNMP
Trap Destination Addresses" for instructions.
2.
Alarms must be configured. SNMP alarm traps sent by the transponder are formatted
according to the SCTE-HMS-ALARM-MIB specification with the following
information included:
SNMP Trap community string:
commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
Default value is "public"
Example Alarm Trap
The example below is a psTamper alarm trap indicating a discreteMinor alarm: Tamper is open.
Data from the raw trap will appear as shown below. Refer to Table 6-6 "SNMP Alarm Trap

Binding #3
alarmLogInformation
OID: 1.3.6.1.4.1.5591.1.2.3.1.2.1
This varbind was designed by the SCTE-HMS committee with the intention of being used by
sophisticated trap interpreters. The information is “coded” within the octet strings:
Octet 1-4: POSIX Time of alarm occurrence (most significant byte first)
Octet 5: Alarm Type (See description below)
Octet 6: Contents of commonNeStatus immediately after alarm occurred
Octet 7-m: Alarm Object Identifier (BER encoded)
Octet n-z: Alarm value (BER encoded)
Most trap interpreters cannot decode this message, which is why varbinds 4 and 5 were added that
provide the same information in a more useable format.
Binding #4
Alarmed Parameter OID/Value
OID:
1.3.6.1.4.1.5591.1.4.2.1.27.1
This field provides the varbind of the parameter that is alarming along with the value of that
parameter. This is the same information encoded in varbind #3 Octets 7 through Z.
In the example above the value would be:
OID: 1.3.6.1.4.1.5591.1.4.2.1.27.1.0 (psTamper)
Value: 2 (Open)
Binding #5
Alarm Location/Type
OID: 1.3.6.1.4.1.5591.1.1.2.1.2
This is the information from varbind #3 Octet 5 above. The alarm location will always be the
SCTE-HMS currentAlarmAlarmState and the type will be determined based on how the alarm was
configured in the SCTE-HMS PropertyIdent MIB tables.
OID 1.3.6.1.4.1.5591.1.1.2.1.2.0 (currentAlarmAlarmState)
Type: 1-7 based on SCTE definitions:
1 NOMINAL
2 HIHI
3 HI
4 LO
5 LOLO
6 Discrete Major
7 Discrete Minor
The Type will be determined by how the alarm is configured in the SCTE-HMS PropertyIdent MIB,
whether it is a Discrete or Analog alarm and the level of alarm defined for that state.
Table 6-6, SNMP Alarm Trap Varbinds and Explanations
Trap on Normal
The DSM3 Series has the capability of sending a “return to normal” trap once an alarmed condition
returns to a normal state. This feature is enabled by default, but can be disabled by setting the
"TRAP ON NORMAL" parameter in the the MIB point atiMgmtSnmpTrapOnNormal to a value of "2".
The contents of this trap message will be identical to the SNMP Alarm traps, but the value of the
Alarm "Type" defined in the 5th varbind will be "1" (NOMINAL).
SCTE-HMS Warm-Start Trap
In addition to the SNMP alarm traps, the DSM3 Series will also send an SCTE-HMS warm-start trap
when it is initialized. Some SNMP monitoring software requires this trap for auto-identification of the
transponder. The format of this trap will be similar to the alarm trap, but the only information sent
will be:
commonTrapCommunityString, OID 1.3.6.1.4.1.5591.1.3.1.11.0
commonPhyAddress, OID, 1.3.6.1.4.1.5591.1.3.2.7
commonLogicalID, OID 1.3.6.1.4.1.5591.1.3.1.1.0
SCTE-HMS Cold-Start Trap
An SNMP-HMS cold-start trap will be generated by the DSM3 Series anytime it initializes with a
new firmware version. In addition, a cold start trap is sent whenever the DSM3 configuration has
changed. If any parameter in the HMS PROPERTY table has changed since the last reset, a
cold-start trap will be sent upon the next reset.

6.0 Data Management
6.2.3 General Power Supply Alarms
General power supply alarms are passed directly from the power supply to the transponder
without specific definition and are classified in the HMS MIB table as psMinorAlarm and
psMajorAlarm. There are a number of problems that can generate these alarms and the exact
nature of the situation is not specified. Minor and Major alarms are defined by the SCTE
standards committee as follows:
psMajor
“Service has been dropped or a service interruption is imminent. Indicates that an immediate
truck roll is appropriate.” Several psMajor alarms are latching, meaning that the alarm won’t
clear until the problem is fixed and after a successful completion of a self-test. A self-test is the
preferred method of verifying the resolution of the alarm condition as cycling the power has the
potential of masking the problem and not indicating the actual state of the system.
psMinor
“A non-service affecting condition has occurred and should be monitored.”
The following table lists the psMajor and psMinor alarm definitions for the XM2 power supply.
NOTE:
The cause of a psMajor or psMinor alarm can be determined by checking the Discretes table in the Alpha MIB
or by viewing the Web page. The cause will have the value of “ALARM.”

7.0 Installation
7.1
Verifying Power Supply Device Address
Before installing the hardware, provision the DHCP server with the cable modem’s RF MAC Address. This
allows the installation to be verified while the technician is on-site, eliminating the need for a second visit if
there are problems with the installation.
WARNING!
To reduce the risk of electric shock, completely remove the inverter module from the power
supply prior to installation. For field installation, use a service power supply to avoid losing
power to the load.
CAUTION!
The DSM3 Series is static sensitive. An ESD wrist strap should be worn when installing the
transponder.
Before removing the Inverter Module (IM), verify the power supply device address is correct.
The power supply device address must not be set to zero and no two power supplies monitored by a
single DSM3 Series can have the same address. Power supplies must have 1, 2, 3, 4 or 5 as an address.
To verify the power supply’s address do the following:
Smart Display Screen
1. Press the Enter key on the inverter module twice to access the SETUP Menu.
2. Press the Down key until DEVICE ADDRESS is displayed.
3. If the address is correct (in the range of 1 to 5), skip to Step 8.
4. To change the address, press the Enter key to enter the Edit mode.
5. Press the Up or Down keys until the desired address (1, 2, 3, 4 or 5) is displayed. Remember, each
power supply monitored by a single transponder must have a unique address; this may require
accessing the menu systems of the additional power supplies and adjusting as applicable.
6. Press the Enter key to load the new address.
7. Press the Enter key again to accept the new data.
8. Press ESC three times to return to the OPERATION NORMAL screen.

Installation / Replacement Procedure in XM2 Power Supplies
If the CableUPS has been shipped without a DSM3 Series module, or the existing module requires
removal and replacement, do so via the the following procedure:
1. Switch OFF the power supply’s battery breaker.
NOTE:
With the battery breaker in the OFF position, the power supply will not go into inverter mode.
2. Unplug all inverter module connections (e.g. battery cable, remote temperature sensor).
3. Loosen the inverter module thumbscrews and slide the inverter module out just enough to disconnect
the ribbon cable. Disconnect the ribbon cable.
4. Slide the Inverter Module out of the power supply.
5. If the inverter module is equipped with a communication module, remove it by loosening the two
Phillips captive screws.

6. Plug the supplied 18-pin jumper into the header on the back of the DSM3 Series circuit board.
NOTE:
To prevent damage to the DSM3, do not reuse the existing 18-pin connector.
Instead, use the jumper supplied with the transponder.

7. Line up the 18-pin jumper with the header on the Inverter Module and connect the unit to the
Inverter Module.
Fig. 7-4, Connecting the Transponder to the Inverter Module
8. Fasten the DSM3 Series to the Inverter Module by tightening the two captive screws. It is
recommended that the screws be tightened alternately, a few turns at a time so the transponder
aligns in parallel to the Inverter Module.
9. Reinstall the Inverter Module and reconnect the ribbon cable. Make front panel connections
(tamper, temperature sensor, battery sense, RF etc.).

Environmental and LA-P-SM Connections
The DSM3x and DPM have the capability to monitor and control enclosure environmental heating and
cooling. Typically this is used for battery mat heaters in cold environments, however the functionality may
be implemented to control enclosure fans or air conditioners. The following section will outline the details
of the controls available and will include an example of a typical battery heater mat configuration and
explanation of the settings.
7.9.1 Connecting the Battery Heater Mat Controller
Power to the heater mat is provided via a customer-supplied controller plugged into the power
outlet inside the enclosure. A cable (Alpha p/n 875-627-22) connects the controller to the ENV
(Environmental) connector on the DSM3x and DPM. The connection procedure is shown below.
1. Connect the 4-pin connector from the controller cable
(Alpha p/n 875-627-22) into the base of the Heater Mat
Controller.
2. Plug the controller into the power outlet.
3. Plug the Heater Mat into the controller.
4. Plug the 6-pin connector into the ENV connector.
Once the connection has been made, Environmental Control Management can be configured on
the transponder's Web page as indicated in the following tables. The Environmental Control MIB
section begins at atiMgmtSysTempMgr (1.3.6.1.4.1.926.1.3.2.4).
Status of the Environmental Control is also available on the transponder’s Web page.

Environmental Control MIBs
atiMgmtSysTempCtrl (1.3.6.1.4.1.926.1.3.2.4.1)
Value list
Description
off(1)
Temperature device is off. This setting is non-volatile, if the variable is in this state upon reset (or power-up) this value will be
retained. This is the DEFAULT factory value for this variable.
onTimer(2)
Temperature device turned on for a predefined time. Before a SET to this state is issued, atiMgmtSysTempTimer is to be SET with
the number of minutes the heater or cooler is to be on. When the timer has expired, this variable will automatically be set to 1.
onTemp(3)
Temperature device controlled by the battery temperature probe. Before a SET to this state, atiMgmtSysTempTemperature and
atiMgmtSysTempHysteresis must be set to the desired temperature values. Once placed into this state, this variable will not
change until another SET to this OID is received. Temperature control is based on the battery temperature probe. If there appears
to be no battery temperature probe, the output to the temperature device will be inactive.
onTimerTemp(4)
Temperature device will be controlled by both the temperature and timer values. When set to this state, the temperature device will
be controlled as if this variable is in state 3, but only for the time defined by atiMgmtSysTempTimer. Once the timer has counted
down to zero, the value of this variable will be returned to 1. This value is volatile, after reset, the state of this variable will be 1 if it
was in this state before the reset.
on(5)
Temperature device is on. This value can be used when the temperature device has a thermostat of its own. However it is recommended, as a safety precaution, that state 3 is used with the battery temp probe being used as a back up in case the device thermostat gets stuck in the "on" state (provided the transponder is connected to the temperature device’s power control). This state
/ mode could also be used if the temperature control line was used for something other than a temperature control. This value is
non-volatile and will remain in this state after a reset.
atiMgmtSysTempStatus (1.3.6.1.4.1.926.1.3.2.4.2)
Value list
Description
contactOpen(1)
The value of this variable reflects the state of the feedback signal from the temperature device. Since not all temperature devices
have a feedback signal, or the operation of the feedback signal may vary from device to device, the meaning of this signal is
implementation specific.
contactClosed(2)
atiMgmtSysTempMode (1.3.6.1.4.1.926.1.3.2.4.3)
Value list
Description
heater(1)
Mode of Operation. The temperature device may be a heater (such as a battery mat) or a cooler (such as an enclosure fan). When
this device is acting as a thermostat, this variable defines the active state. If this variable is set to "heater", the temperature device
will be active only when the temperature is below the defined level. If this variable is set to "cooler", the temperature device will be
activated when the temperature is above the defined level. The DEFAULT factory setting for this variable is heater(1). This variable
is non-volatile and its value will be retained when the device is reset.
cooler(2)
atiMgmtSysTempActiveState (1.3.6.1.4.1.926.1.3.2.4.4)
Value list
Description
closed(1)
This variable defines how this device creates the active state. When this variable is set to "closed(1)" the active state will be represented by the drive pin being shorted to ground and high impedance will represent the inactive state. When this variable is set
to "open(2)" the active state will be represented by the drive pin being high impedance in the active state and shorted to ground in
the inactive state. The DEFAULT factory state for this variable will be 1. This variable is non-volatile and the value will be retained
when the device is reset.

Size list
Description
1...70
Thermostatic temperature setpoint in degrees centigrade. When this device is set to control the temperature device based on
temperature, this variable (along with the hysteresis variable) will be used to determine when the temperature device is to be
turned on and off. This value is compared to the value from the battery temperature sensor. The DEFAULT factory state for this
variable will be 0 (once changed, it may not be put back to zero, providing an indication that the value has been adjusted). This
variable is non-volatile and the value will be retained when the device is reset.
atiMgmtSysTempHysteresis (1.3.6.1.4.1.926.1.3.2.4.6)
Size list
Description
1...10
When the device is controlling the temperature device thermostatically, this value is used to keep the temperature device from
going on and off too often. If the temperature device is a heater, the device will be turned on when the temperature reaches the
setpoint but will not be turned off until the detected temperature overshoots the set point by this amount. When the temperature
device is a cooler, the device will be turned on when the temperature reaches the set point, but will not turn off until the detected
temperature undershoots the set point by this amount. The DEFAULT factory state for this variable is 1. This variable is nonvolatile and the value will be retained when the device is reset.
atiMgmtSysTempTimer (1.3.6.1.4.1.926.1.3.2.4.7)
Size list
Description
0...1440
When the temperature device is controlled using the timer, this is the number of minutes the temperature device will be active.
The DEFAULT factory state for this variable is 30. This variable is non-volatile and the value will be retained when the device is
reset.
atiMgmtSysTempCountdown (1.3.6.1.4.1.926.1.3.2.4.8)
Size list
Description
0...1440
When the temperature device is controlled using the timer, this is a countdown that will indicate how many minutes before
the device will become inactive. The value of this counter is undefined when the device is not active in a timer mode. Anytime
atiMgmtSysTempCtrl is SET to a value that indicates timer mode, the value of atiMgmtSysTempTimer will be copied into this
variable. If, while this variable is counting down, atiMgmtSysTempCtrl is again SET to a value that represents a timer mode,
the value of atiMgmtSysTempTimer will again be copied into this variable and the count will start over again. The temperature
device will change to inactive when this count drops to zero. At zero the counter will stop.
atiMgmtSysTempStatusInvert (1.3.6.1.4.1.926.1.3.2.4.9)
Value list
Description
noInvert(1)
The default value of this variable is noInvert(1), which provides a contact closure when the temperature device is on. When
this parameter is set to invert(2), the returned value for the contact status (atiMgmtSysTempStatus) will be inverted (contact
closed will be reported as open, contact open will be reported as closed). This accommodates the differences in which the
manufacturers of the relay block have implemented the open versus closed status contacts. This variable is non-volatile and the
value will be retained when the device is reset.

Connecting the LA-P-SM
The DSM3x Series and DPM transponders are capable of monitoring the status of the Alpha
LA-P-SM series surge suppressors. The physical installation is shown below and consists of
connecting the cable (Alpha p/n: 875-627-23) from the LA-P-SM's two leftmost screw terminals to
the six pin ENV connector on the DSM3x or DPM and plugging the LA-P-SM into the enclosure‘s
power outlet.
1. Insert cable into 3-pin
connector
2. Tighten to .22 to .25N•m
4. Plug LA-P-SM into power outlet
3. Connect to LA-P-SM
5. Plug cable into ENV connector
7.12.1 Configuring the LA-P-SM
A MIB value must be set to enable monitoring via SNMP or the transponder’s Web page. To
do this, set the following OID to a value of 2 (installed). On the Web page, go to the "Advanced
Configuration" on the main menu and then click on the sub-menu "IO-Environment". Click the
"Installed" button.
For help accessing the transponder Web page, consult Section 4.
atiMgmtSysLAPInstalled (1.3.6.1.4.1.926.1.3.2.8.1)
Once this OID has been set, the following information will be available via SNMP and the Web
page:
atiMgmtSysLAPState (1.3.6.1.4.1.926.1.3.2.8.2)
Value list
Description
notInstalled(1)
NO LAP INSTALLED. This would be the case if the OID atiMgmtSysLAPInstalled has not been set to a value of 2.
ok(2)
OK. Indicates that each connected power supply detects AC input and the LAP device reports no fault. Normal operation.
acNotPresent(3)
AC OFF. One or more of the power supplies detects no AC. To check if the LAP has failed, query the OID psInputVoltagePresence (1.3.6.1.4.1.5591.1.4.2.1.34) to ascertain if the line has truly failed; if this is the case, the LAP is
working normally. If the line is OK, it is likely the LAP has a problem.
relpaceLap(4)
Critical Surge Event - Replace LAP. An LAP has failed and should be replaced. This is the state when all power supplies detect AC but the LAP sense line indicates a fault.
invalid(5)
There is a fault, either the LAP has not been wired correctly or the relay in the LAP is stuck in the no-fault state. This
state occurs when at least one power supply senses AC fail, which should cause an LAP fault, but no fault is detected
(this would be the case if the LAP relay is stuck in the ON condition).
7.12.2 Simultaneous Usage, Environmental Control and LA-P-SM
The environmental control and the LA-P-SM may be implemented simultaneously. This
configuration requires interface cable Alpha part number 875-627-24. Control and monitoring
are identical to the devices being used independently. Sections 7.9 through 7.12 may be used to
install, connect, and set MIB points for operation.

The DS and REG LEDs on the front of the DSM3 Series should be ON solid green. This indicates
successful registration with the headend. In addition, the RF LED should also be ON solid green
indicating proper RF power levels and the ALM/RDY LED should be blinking green for normal
operation.
With the DSM3 Series used in conjunction with the XM2-HP power supply, network connectivity
can be verified via the smart display. For other power supply models, verify the network status via
the Ethernet port.
Connect a computer’s network port to the transponder’s Ethernet port using a standard network
cable. Launch an Internet browser and enter 192.168.100.1 into the Address. The transponder
will return the Web page shown below. Click on “General” to display the key communications
parameters including upstream and downstream power levels and the cable modem’s IP address,
which confirms connectivity.

System Status Indicators and Reset button
As viewed from the front of the unit, the DSM3 Series utilizes light emitting diodes (LEDs) to indicate
system status. During system startup, the LEDs will first blink momentarily then indicate the current status
of a variety of parameters on the DSM3 Series transponder. The LEDs indicate alarms, RF power level
status, battery string connectivity and communications activity with the network. A description of each LED

Fig. 9-3, LED Functionality and Indications
9.4.1 Detailed LED Descriptions
After power is applied or a reset occurs, all LED's will flash in certain patterns indicating the cable
modem chipset is starting or restarting. Once it is ready it will begin the DOCSIS requirement of
searching for the downstream frequency lock and the LED's will follow the detailed descriptions
below.
ALM/RDY - Alarm/Ready
The ALM/RDY - During normal operation, this LED blinks GREEN, indicating a heartbeat pulse
from the processor. The frequency of flashing by this LED provides a visual alert for power
supply discrete major and minor alarms, if configured in the property and discrete property tables
of the SCTE-HMS MIB. The ALM LED (RED) is factory defaulted OFF. Refer to Section 6.3
for information on configuring the DSM3 Series for active monitoring and alarming. If an event
triggers an HMS alarm, the ALM/RDY LED blinks RED according to the alarm type until the alarm
has been resolved. For a minor alarm, the frequency of flashing (RED) will be more OFF than
ON and for a major alarm the frequency of flashing will be (RED) more ON than OFF. If there are
multiple active alarms, including one or more major alarms with one or more minor alarms, the
major alarm will take precedence in terms of the indication.

Detailed LED Descriptions, continued
REG - CM Registration
Once a downstream channel has been negotiated between the CM and CMTS, the modem
attempts to register with the DHCP server and obtain the configuration file. This LED flashes
while the process takes place. Once the registration is complete, the LED will remain on solid.
This is the best indication that the DSM3 Series is communicating with the CMTS in the headend.
DS - Downstream Communication
This LED indicates the state of the CM's attempt to gain a downstream signal. This process may
take several seconds, depending on how long it takes the CM to locate a carrier signal and lock
onto a channel. The LED flashes while searching for the downstream DOCSIS channel and is on
solid when the downstream channel is locked.
ACT - CPE Activity
The CPE activity LED flashes to indicate that data is being transmitted or received between the
DSM3 Series and a network device.
LNK - Network Communication Status
The Ethernet link LED remains ON when there is an active connection on the Ethernet port (e.g.,
a computer is connected for local diagnostics).
Rx/Tx Power
The Rx/Tx PWR LED utilizes a tricolor LED to provide the installer a quick verification of the modem transmit (Tx) and receive (Rx) RF power levels. The Rx/Tx PWR LED will illuminate “green”
when both the cable modem Tx and cable modem Rx RF power levels are within the range as
specified in the SCTE-HMS PropertyTable. The LED indicator illuminates “blue” when Rx and/or
Tx levels are within the “warning” range as specified by the SCTE-HMS PropertyTable. The LED
indicator illuminates “red” when Rx and/or Tx levels are outside the range as specified by the
SCTE-HMS PropertyTable.
Refer to the following table for default ranges in the SCTE-HMS PropertyTable:

* Values in ( ) denote behavior of the Rx/TX LED if alarmEnable bits are set to ‘00’.
By default, alarmEnable is set to 00 (disabled) to prevent unwanted SNMP traps but the LED
behavior will function as if the alarmEnable were set to the values in the above table. If the alarm
Enable bits are set to anything other than 00 the LEDs will then follow the behavior of the desired
enable bit setting.
The above default values translate into the following Rx/Tx Power LED color ranges:
LED Color
Rx Range (dBmV)
Tx Range (dBmV)
Green
+10 to -10
0 to +50
Blue
+15 to +10 and -10 to -15
+50 to +55

In addition to the above SCTE-HMS PropertyTable entries, the Tx and Rx levels displayed on the
DSM3 Series Web page will each provide colored indicator bars that correlate to the RF LED and
SCTE-HMS PropertyTable thresholds.

Fig.9-4, DSM3 Series Web Page, RF Power Level Indicators
Configuring the Rx/Tx Power LED - Custom Settings
If desired, the RF Power Level ranges for the Rx/Tx PWR LED may be customized via
SNMP by adjusting the HiHi, Hi, Lo, LoLo values for the docsIfDownChannelPower and
docsIfCmStatusTxPower in the SCTE-HMS Property Table (OID:1.3.6.1.4.1.5591.1.1.1). Be
careful not to exceed the Input Level and Output Power range specifications of the DSM3 Series
transponder.
COM - AlphaBus Communications
The COM LED indicates any data traffic being received by the DSM3 Series through the COM
(AlphaBus) port. This LED will also blink with one to three blinks approximately every 10 seconds,
which indicates communication exists between the DSM3 Series and other connected devices,
such as a generator or additional XM2.
BAT A/B - Battery Strings A & B
The LED indicator remains ON solid when the battery string wiring harness is correctly connected
to the batteries and the Bat A/B connector on the DSM3 and DSM3x Series.
BAT C/D - Battery Strings C & D
The LED indicator remains ON solid when the battery string wiring harness is correctly connected
to the batteries and the Bat C/D connector on the DSM3x.
9.4.2 Resetting the Transponder
Should the need arise to reset the transponder locally, such as in the case of adding additional
power supplies, a generator, or carrying out maintenance activities, do the following:
Press and hold the reset button (RST) for approximately three (3) seconds until the ALM/RDY
LED stops blinking and turns solid (green). Release the button. The transponder will perform its
power up sequence.
9.5
Verifying Communications via the Headend
Using SNMP, check connectivity by verifying power supply data by doing the following:
• With a MIB browser check power supply data in the psIdent MIB branch (1.3.6.1.4.1.5591.1) of the
SCTE-HMS tree.
• With network management software, verify the DSM3 Series has been identified and is reporting data
correctly.

13.0 Dual IP Mode (Addendum)
13.1
Overview
The DSM3 Series can operate in either Single (default) or Dual IP Mode. In Single IP mode, data from
both the cable modem and power supply are accessed and managed through the modem’s IP address on
the secure private modem network. In Dual IP mode, the transponder acts like a CPE device to the cable
modem and registers a second IP address on the public CPE network.
The following table lists some of the common characteristics of the DSM3 Single IP and Dual IP
configurations:
Single IP
Dual IP
Network
All data from both the cable modem and power
supply are accessed and managed through
the modem’s IP address on the secure private
modem network.
The transponder acts like a CPE device to the cable
modem and registers a second IP address on the public
CPE network.
Data Access
The Network Management System requires
access to the same private modem network.
Dual IP mode allows the power supply data to be
accessed and managed from anywhere within the
public (CPE) network.
Security
Communication with the transponder is limited
to the private LAN network, and is very secure.
Since the transponder is a CPE on the public network,
access may be less secure.
IP Addresses
Where the IP address pool is limited, there is
no need to issue the transponder a CPE IP
address. Only one (1) IP Address is required for
the cable modem of the DSM3.
The CPE requires its own IP address, which may be
in short supply. A total of two (2) IP addresses are
required, one for the cable modem and one for the
transponder.
Data Management
Access to the transponder is limited to the
private LAN network making data management
less versatile, especially for field personnel.
The transponder is accessible on the public (CPE)
network. This makes data management more versatile
for field personnel.
Table 13-1, Single IP Mode versus Dual IP Mode
One CM IP address only accessible on the private (LAN)
network with access to both CM and transponder data.

Web Comparison, Single IP Mode/Dual IP mode
To easily determine the configuration of the transponder when viewing it on its web page, check the
Configuration Line as well as the entries for the CM and CPE addresses. A single IP transponder will
display a CM MAC address only, while a dual IP transponder will also indicate a CPE address.

Configuring Dual IP Mode
To switch the DSM3 Series transponder from Single to Dual IP Mode the atiMgmtSnmpSnmpCPEAccess
parameter of the Alpha MIB will need to be enabled. The Dual IP enable setting can be set through the
DOCSIS Configuration file, the DSM3 Setup File (atidoc03.cfg) or remotely using SNMP by setting the
following Alpha MIB:

Refer section 3.2.4 for details on using the atidoc03.cfg file to propagate custom settings to
field-deployed DSM3 Series transponders.
In Dual-IP mode, the DSM3 Series will first attempt to download the proprietary configuration
file atidoc03.cfg through the CPE’s interface from a TFTP server on the CPE network. In many
networks, the TFTP server is blocked or disabled, so the DSM3 Series also has provisions to
download this file through the Cable Modem interface from the modem’s provisioning server if
necessary. The filename and TFTP server location may also be specified through special tags in
the DHCP Offer, refer to section 13.3.3 for details. Similiar to Single-IP mode, any DSM3 Series
proprietary SNMP MIB setting may be placed in the modem’s DOCSIS configuration file which
would eliminate the need for atidoc03.cfg.
13.3.2 Changing Default atidoc03.cfg Download Settings in Dual-IP Mode
The following table explains the download options available for the atidoc03.cfg file in Dual-IP
mode. The ‘Download Interface’ indicates the network from which the DSM3 series will attempt
to download atidoc03.cfg, either the CPE network or the more secure cable modem management
network.

13.3.3 Specifying atidoc03.cfg name and location via DHCP Tags
In the User-defined area of the DHCP Tags, above option 192, the TRANSPONDER will look for
the following value:
Tag: [Insert Unique Tag Name, e.g. ‘ati-tag’]
Value: aticonfig
In the Tag value immediately following will be the value for the TFTP server to use:
Tag: [Insert Unique Tag Name, e.g. ‘ati-ip’]
Value: IP address of TFTP server (i.e. 192.168.1.51)
Immediately following will be the value for the config filename
Tag: [Insert Unique Tag Name, e.g. ‘ati-name’]
Value: =atidoc03.cfg (an equal sign needs to be in front of the filename for the DHCP server
to recognize this as a valid entry.)

Dual IP SNMP Community Strings
The transponder community strings used for the CPE Transponder in Dual IP mode can be configured
by the operator. The default transponder read-only community string is AlphaGet. The default read-write
community string is AlphaSet. These settings can be configured with the DOCSIS Configuration File, the
DSM3 Setup File (aitdoc03.cfg) or remotely using SNMP by including the parameters below:
NOTE:
These community strings are only applicable for CPE access in Dual IP mode. CM access in both Single
IP and Dual IP modes use standard DOCSIS community strings set through the modem configuration file's
docsDevNmAccessTable. See Section 3.2.1.

Security in Dual IP Mode
In Dual IP Mode, additional SNMP security to the DSM3 Series proprietary MIBs is required since the
transponder and power supply data is exposed on the CPE network, which may be more vulnerable to
packet sniffing and community string deciphering than on the secure cable modem network.
There are two methods of providing SNMP Security in Dual IP Mode: the Data Access Key (Default), and
the Secure Access List.
Method 1: Dual IP Security Using the Data Access Key
In Dual IP Mode atiMgmtSnmpAlphaSetAccess is the only SNMP parameter within the Alpha
proprietary MIB with SNMP-write access on the CPE network by default. When this parameter is
set to the value of the parameter atiMgmtSnmpAlphaSetKey, the data access key, SNMP read/write
access is granted to all parameters in the Alpha MIB tree with read/write attributes. When this access
is granted, the value of atiMgmtSnmpCPESetEnabled is automatically changed to "2" (enabled). After
the operator is finished setting the SNMP variables, SNMP write access can be disabled by setting the
atiMgmtSnmpCPESetEnabled to "1" or by setting atiMgmtSnmpAlphaSetAccess to any value other than
the data access key or by performing a reset to the DSM3 Series.
The data access key parameters can be changed from the default values through the DOCSIS
Configuration File, the DSM3 Series Setup File (atidoc03.cfg) or remotely using SNMP by including the
following Alpha MIB parameters:
MIB Parameter

atiMgmtSnmpCPESetEnabled
1.3.6.1.4.1.926.1.3.1.3.5.0
Corresponds to whether
or not the action taken on
atiMgmtSnmpAlphaSetKey was
successful. Once enabled, writing
1 to this variable will disable CPE
sets.
1 = Disabled (False)
2 = Enabled (True)

Method 2: Dual IP Security Using the Secure Access List
The DSM3 provides an alternative method of providing additional SNMP security in Dual IP by limiting access
to the transponder’s CPE address. The Secure Access List method limits remote SNMP access to four IP
addresses. Only the IP addresses listed in the SNMP Access Table are able to read or write to the Alpha MIB
parameters from the public (CPE) network. This method overrides the default "Data Access Key" method.
The IP address entries in the SNMP Access Table can be set through the DOCSIS Configuration File, the DSM3
Setup File (atidoc03.cfg) or remotely using SNMP by including the following Alpha MIB parameters:
