Controlling E3/T3 Services over
Incumbent Carrier’s Infrastructure
Typical user
Service providers that use access
infrastructure of other carriers
Typical application
Remote monitoring and fault
isolation of E3/T3 services
Quality of Service enhances competitive edge
In today’s open communications market, many alternative carriers and service providers are
competing head to head with incumbent carriers for high speed data services customers. Since
most new service providers have limited access networks, they use the incumbent carrier’s
infrastructure, which is made available to them according to government regulation in many
countries. This situation makes it difficult for new carriers to ensure the quality of their service
end-to-end across the entire network because the traffic is traversing another carrier’s access
segment. For this reason, alternative service providers are looking for access equipment to
overcome this problem and enable them to run diagnostics and performance monitoring up
to the customer premises.
What makes the PRBi-E3 and PRBi-T3 effective tools for alternative service providers?
Features
Benefits
Transparent to E3/T3 and upper layer
protocols
Enables service usage without any protocol limitation
No need for protocol conversion and/or configuration
Real-time indication on service availability
(dial-out)
Enables service providers to take proactive steps to increase
and assure service availability
In-band diagnostic loop operation
Eliminates the need to send a technician to the customer
premises in order to isolate a faulty condition
Remote configuration and diagnostics
(dial-in)
Saves maintenance costs and efforts
Easy, minimal configuration
Saves installation costs and time
RADview SNMP management application
User-friendly interface saves time and training efforts
Clear indication of system status
Simple configuration
Converts HSSI to E3/T3 interface
Enables connectivity of high speed routers
with a HSSI interface to public services
Enabling end-to-end management of E3/T3 services
RAD’s solution is the PRBi-E3™ and PRBi-T3™. These intelligent, customer-located network
termination units were developed at the request of leading international carriers, for termination
of E3/T3 services. The equipment detects and isolates network faults end-to-end, based on realtime alarm indication and loopback activation/deactivation. This solution, therefore, enables
service providers to ensure Quality of Service across the network, up to the customer premises.
The PRBi-E3 and PRBi-T3 devices alert the RADview™ application via dial-up modem if a fault
is detected. For fault isolation, the device automatically detects a pattern in the E3 or T3 header
coming from the network port for in-band indication to activate/deactivate a diagnostic loopback.
The RADview standard SNMP application, running on the HP OpenView UNIX or PC platform,
provides a user-friendly interface for monitoring and configuring a remote PRBi-E3 or PRBi-T3
unit. The loops can also be activated/deactivated out-of-band using the dial-up modems.

Disadvantages of Alternative Solutions
Rely on the incumbent carrier’s service
guarantees
Limited assurances of service quality
No (or minimal) control, diagnostic or fault isolation options
Deploy an SDH node
Provides more features than required
Much more expensive
Use a protocol-dependent device
(for example, ATM NTU or IP router)
