Accessing the Wireless Cable Modem Telnet
Interface
To access the Telnet Interface complete the following steps:
1. The Wireless LAN Cable Modem Telnet Interface can be accessed
remotely or locally. If accessed remotely, the Wireless Cable Modem’s
DHCP-assigned IP address must be used. If accessed locally, telnet to
192.168.100.1 (this is the default Wireless LAN Cable Modem Router
Telnet IP address).
2. Enter the Cable Router Telnet login and password assigned to the
Division Personnel by Ambit. Each authorized user will receive the login
and password for his/her appropriate user level. There are four user
levels based on the required access rights for the tasks related to the user
functions. Ambit and the Time Warner Cable Division will determine the
appropriate user level for personnel needing access to Telnet.
Engineering, Installers, and Support Personnel will need access to Telnet.

Required Installation Configuration in Telnet
At the time of installation, the first two settings MUST be configured via Telnet.
The third command can be set through the web Access User Interface or directly
in Telnet. The final step is to enter the reset command to save the new settings
and verify that the configuration is correct. The following steps details this
process:
1. NAT must be enabled directly in Telnet. The command to enable NAT is
the following:
•
Telnet Syntax: ip nat enable
2. The number of computers to be included in the network must be indicated
in the IP pool setting directly in Telnet. The Time Warner Cable minimum
is two and the maximum is four.
The factory default setting is 20 in Pool Index 1. The default setting must first be
deleted before the new setting can be entered. Two commands will be
necessary: ’dhcp ip pool delete 1’ to delete the default Pool Index 1and then
‘dhcp ip pool add (the first IP address to be included and then the last IP address
to be included). See Set the DHCP server IP pool range for more information on
this command.
•
Telnet Syntax: dhcp ip-pool delete 1
dhcp ip pool add {start IP} {end ip}
This command must be executed in order to limit the number of devices a
customer can add to the home network.
3. WEP must be enabled and the key established. This can be done directly
in Telnet or via the Web Access User Interface.
If Telnet is used directly to enter this information, 64 bits is the Time Warner
Cable encryption standard with Ambit’s Wireless Cable Modem. Ten
hexadecimal digits will need to be established as the key.
•
Telnet Syntax: interface wireless wep 64bits key (xxxxxxxxxx)
4. The Division will need to establish a common key to use in all installations.
Replace xxxxxxxxxx in the above syntax with the selected key.
5. Enter the reset command to put the new configuration into effect. Settings
will not be saved until the reset command is executed.
•
Telnet Syntax: reset
6. Finally, enter the Show the System Running Information command (‘show
running-configuration’) to verify that all settings are appropriate per the
Time Warner Cable and division standards.
•
Telnet Syntax: show running configuration

CM>dhcp ip-pool add 192.168.100.2 192.168.100.5
CM>interface wireless wep 64bits key 028A0EE9DD
CM>reset
Set the Wireless LAN Cable Router Access Point Set the Service Set ID (SSID)
Note: This setting must be entered but can be done using the Web User
Interface SSID (mandatory). (SSID) as designated by division policy. The same
SSID must be assigned to all wireless devices in the network. The default SSID
is WLCM.
If the Telnet command must be used instead of the Web User Interface, the
command is as follows:
User: Installer (depending on the Telnet configuration method selected by the
division) and TWC Support.
When: Installation, Maintenance, or Troubleshooting.
Telnet Syntax: interface wireless ssid {ssid name}
Example:
CM>interface wireless ssid Ambit
This example sets the SSID to Ambit.
Set the Wireless LAN Cable Router Channel
Note: This setting must be entered but can be done using the Web User
Interface Channel (mandatory). The default setting is channel 6, which is the
Time Warner Cable Standard.
If the Telnet command must be used instead of the Web User Interface, the
command is as follows:
User: Installer (depending on the Telnet configuration method selected by the
division) and TWC Support.
When: Installation, Maintenance, or Troubleshooting.
Telnet Syntax: interface wireless channel {1~11}
Example:
CM>interface wireless channel 6
This example sets the wireless channel to Channel 6.
Set the Wireless LAN Cable Router Access Point WEP key
Note: This setting must be entered but can be done using the Web User
Interface WEP Key (mandatory). The Time Warner Cable Standard is 64 bit
encryption, which consists of ten (10) hexadecimal digits (any combination of 0-9,
af, or A-F).
The Division will need to establish a common key to use in all installations.
If the Telnet command must be used instead of the Web User Interface, the
command is as follows:
User: Installer (depending on the Telnet configuration method selected by the
division) and TWC Support.
When: Installation, Maintenance, or Troubleshooting.
Telnet Syntax: interface wireless wep {64bits|128bits } key
(xxxxxxxxxx|xxxxxxxxxxxxxxxxxx)
Note: The standard encryption key type for Time Warner Cable is 64- bits with
the Ambit Wireless Cable Modem.
Disable the Wireless LAN Cable Router Access Point WEP Key
User: Installer (depending on the Telnet configuration method selected by the
division) and TWC Support.
When: Installation (only if needed to get the desired WEP setting configured) or
Troubleshooting.
Telnet Syntax: interface wireless wep disable
Note: WEP must not be left disabled. It may be used when Troubleshooting
during or post installation.

NAT in Telnet
Network Address Translation/Port Address Translation (NAT/PAT) gateway is
designed for IP address simplification and conservation, as it enables a private IP
network that uses no registered IP addresses to connect to the Internet.
NAT/PAT operates on a wireless LAN cable modem, connecting to the Internet,
and translates the private (not globally unique) addresses in the internal network
into legal addresses before packets are forwarded onto the Internet. As part of
this functionality, NAT can be configured to advertise only one address for the
entire network to the outside world. This provides additional security, effectively
hiding the entire internal network from the world behind that address. NAT has
the dual functionality of security and address conservation, and is typically
implemented in remote access environments.

Managing Modem Access from IP or MAC
Addresses
There are four types of commands used to block specific IP addresses or MAC
addresses from accessing the modem.
•
The standard IP access list performs packet filtering based on source IP
address from the CPE host(s). (Access list numbers 1~20 in the
command line points to this type of filtering.)
•
Manage Telnet access: The management access list performs packet
filtering based on destination IP address matching the Wireless LAN
Cable Router IP address. Management access includes Telnet, Web
based interface, & SNMP. (Access list numbers 21~40 in the command
line points to this type of filtering.)
•
The standard MAC access list performs frame filtering based on source
MAC address from the CPE host(s) via Ethernet or USB interface.
(Access list numbers 41~60 in the command line points to this type of
filtering.)
•
The wireless MAC access list performs filtering based on the source MAC
address from the wireless card. Configuring this list will make only the
wireless card’s MAC address that match this list able to associate to the
wireless AP. (Access list numbers 61~80 in the command line points to
this type of filtering.)
The number selected for the access list in the command line indicates the type of
filtering to be executed. The following numbering conventions must be followed:
1~20, access list ID, for the standard IP access list
21~40, access list ID, for the management (Telnet) access list
41~60, access list ID, for the standard MAC access list
61~75, access list ID, for the Wireless MAC access list
