Feature Description:

Caller ID

Caller ID (type 1 only) on Analog voice interfaces on MC3810, 2600, 3620, 3640 and 3660 platforms. It will support BellCore and ETSI standard for both FXS and FXO analog interfaces. This feature is a crucial requirement for Enterprises and Managed Service Providers deploying VoIP, VoFR and VoATM. 

Digital T1/E1 Packet Voice Trunk ISDN PRI 

Features deferred from Phase I of Copland project are added in Phase2, a.k.a. "Amadeus". These are significant to the planned market strategy for the Copland (NM-HDV) project. The below features were added to Copland:

  • - ISDN-PRI (user side and network side), T-CCS, Datawan, FG-D, R2, RAI, E1 CAS
Network Side ISDN PRI Signalling, Trunking & Switching 

Provides a package of requirements to support call switching through the AS5800 network access server when using Network Side PRI which consists of the following 4 featurettes:

  1. Dial Peers: Modifications to the dial peer code by TISU to accommodate the call switching capability developed in the AS5800
  2. AS5800 Call Switching: Upon receiving a call with SS7 signaling, the AS5800 analyzes the dialed digits and if required forwards the call outward using network PRI signaling.

  3. ISDN Network Side PRI: Modifications to the Network Side PRI implementation to accommodate using the dial peer code to define the trunking arrangements. Using the current dial peer feature, the largest trunk group size will be DS1. NI-2 signaling will be added to the Network Side PRI feature.

  4. Creates a "Trunk Group" for DID with the following components:
    • list of applicable interfaces
    • size of the trunk group
    • list of telephone numbers that will be directed to this group of PRI's or channeled interfaces
    • call types allowed to be delivered to this group of PRI's or channeled interfaces.

Hoot n' Holler 

Implements Hoot n' Holler multicast conferencing feature on the 2600, 3620, 3640, 3660. Hoot n' Holler networks are used throughout the brokerage industry to communicate the Morning Report as well as to advise the trading community within a brokerage firm on market movements, trade executions and so on. It is also used in media companies, prisons, subways, and machine tool companies.

T1 remote loopback, EADI, CSU/DSU MIB, CLI reset 

A set of featurettes that add the following capabilities to the T1/E1-VIC for the 2600 and 3600 family of routers:

  • T1 remote loopback
  • CLI reset
  • E1 Drop and Insert w/ Signaling
  • Extended Availability Drop and Insert (EADI) 
  • CSU/DSU MIB.
Call Tracker 

Contains the following features which enhances the maintainability of our dial products and allows us to displace competitors

  • Call Tracker - This feature allows us to track active call status and maintain a database of disconnect calls. 
  • Provide customer the ability to busy-out DS0 using SNMP.
  • AOL TCP
  • Ascend Attribute 155 - Allowing multicast users to be enabled via Radius.

UPC324 - Universal Port Card for AS5800

  • 324 Port "Universal" Port Card for AS5800 - Enables 3T3 AS5800 density
  • The UPC324 card implements the latest Cisco DSP technology via the Conexant CSMv6 DSP chips. Each port on these cards can be dynamically configured via software to process modem, voice or FAX calls on a per port basis, with various modulations, voice codecs being implemented in the same (upgradeable) DSP firmware.
  • Initial software release supports data functionality only. Digital and analog calls can be terminated.
  • An AS5800 with 7 UPC324 cards and 2 VXR router shelves can support a 3CT3, or more, ingress environment - that is, 2016 to 2048 data calls in a single AS5800 system. This represents a > 50% increase over the current supported density. 
PIAF 
  • Allows a Mica modem-bearing platform (AS5300 and AS5800) to terminate data calls from users using PIAFS wireless phones. PIAFS service is available in Japan.
  • The former Cisco solution is based on implementation by NEC acting as an OEM vendor on the AS5200. This solution is a PIAFS only interface board. AS5200 is now EOL.
  • MICA Portware will provide a PIAFS-only image. 

  • There are also requirements for Resource Pool Management (RPM) support and an extension to the NAS-Port-Type definitions to allow AAA/RADIUS accounting to log a Port Type connection of PHS/PIAFS.
NOTE:
The features delivered with this XED release will be immediately incorporated into Cisco IOS Software Release 12.1(3)T and subsequent Cisco IOS 12.1T releases.
