Release Notes for Cisco 7000 Family for Cisco IOS Release 12.1 T
78-10811-05
New and Changed Information
Voice Over Frame Relay Configuration Enhancements
Platforms: Cisco 7200 series routers
Voice over Frame Relay functionality has been updated in this release, so that configuration on all
supported platforms is nearly identical. In Cisco IOS Release 12.0(4)T, when support for Voice over
Frame Relay using FRF.11 and FRF.12 was introduced, configuration procedures were different
depending on the router platform used.
Some commands introduced in earlier Cisco IOS releases have been removed or modified. Refer to the
“Voice over Frame Relay Using FRF.11 and FRF.12 Configuration Updates” feature module for a
description of the configuration procedures effective in this release.
This feature provides consistency for configuration requirements across the hardware models that
support Voice over Frame Relay: the Cisco 2600 and 3600 series routers, the Cisco 7200 series routers,
and the Cisco MC3810 multiservice access concentrator. In previous releases, configuration procedures
on the Cisco MC3810 were different from those on other routers.
New Hardware Features in Release 12.1(1)T
The following new hardware features are supported by the Cisco 7000 family for Cisco IOS Release
12.1(1)T:
Two-Port Moderate-Capacity T1 and E1 Digital Voice Port Adapter
Platforms: Cisco 7200 series routers
Cisco digital voice port adapters for the Cisco 7200 series routers provide large-scale voice and fax
termination for PBXs, and the Public Switched Telephone Network (PSTN) using Voice over IP (VoIP)
or Voice over Frame Relay (VoFR).
The digital voice port adapter is a highly integrated solution offering a leap forward in voice-channel
density and application flexibility. This single-width port adapter incorporates two universal ports that
can be configured for either T1 or E1 connections with high-performance digital signal processors that
support up to 48 channels of compressed voice. Integrated channel service units/digital service units
(CSU/DSU) echo cancellation, and digital signal level 0 (DS-0) drop and insert functionality eliminate
the need for external line-termination devices and multiplexers, simplifying network design and
management.
New Software Features in Release 12.1(1)T
The following new software features are supported by the Cisco 7000 family for Cisco IOS
Release 12.1(1)T:
AAA Broadcast Accounting
Platforms: Cisco 7200 series routers
The AAA Broadcast Accounting feature allows accounting information to be sent to multiple authentication,
authorization, and accounting (AAA) servers at the same time; that is, accounting information can be
broadcast to one or more AAA servers simultaneously. This functionality allows service providers to send
accounting information to their own private AAA servers and to the AAA servers of their end customers. It
also provides redundant billing information for voice applications.
