Cisco Multiservice Packet Network Solution Overview

Chapter 2 Solution Components
Call Agent
These dual processors and dual Ethernet cards (providing four Ethernet interfaces) allow the OPM to be
divided into two independent sides, providing full redundancy.
The multiservice cards provide the telephony and signalling functions (UFSDSP) and recorded
announcements and signalling functions (UFSGAV).
Note The UETDSP card, a hardware evolution of the UFSDSP telephony and signalling card is not supported
in releases 2.0 and 2.1 of the Cisco Multiservice Packet Network Solution.
Each line card (USTM1N) provides one Synchronous Digital Hierarchy (SDH) STM-1 interface
(155 Mbps supporting 63 trunks at 2 Mbps), with either optical or electrical interfaces. Optical STM-1
SDH interfaces (TOSTM1) have line protection using automatic path selection (APS) according to
ITU-T G.783; electrical STM-1 SDH interfaces (TESTM1) have Equipment Protection Switching.
The switching matrix (UMAPER) and enhanced switching matrix (UMA04K) cards support 2000 and
4000 DS0s respectively. These two cards are mutually exclusive within one OPM.
For releases 2.0 and 2.1 of the Cisco Multiservice Packet Network Solution, the line cards require an
ADM (either third party or Italtel) to handle the E1 lines for both the iMSS-4040 and iMSS-4050, and
to handle PRI and V5.x connections for the iMSS-4040. The ADM is also required to handle the
communication with the VISM if there is no STM-1 connection on the VISM.
Interconnection Structure Module
The ISM allows TDM switching to be extended over multiple OPMs. The ISM can be used only in
distributed and multi-module iMSS-4040 configurations. See the “Configurations” section for sample
configurations.
