Communication control module that
interlinks CPM, LIM,SPM and CNET
through HDLCAdmin and
maintenance processing and
online data setting.
Alarm board for all system alarm processing.
BUS control process board.Used for BUS
communication b/w AMP and
CDP.
Central database processing and management of common
resources.Deals location selection of PBX,
trunk line etc.
Provides communication bridge b/w OAM and WS.It consists of KVMS, LAN switches, Server and storage media.All the database and programs required by the system are stored here.
Centralized clock synchronization to
the whole exchange.
High Speed interface board that interconnects LIM,CNET and CCM.Provides Speech and Signaling path.
Line Interface Module provides linkage of
incoming and outgoing traffic to the AM/CM..It contains optical and
electrical interfaces at different data rates defined along with a specified capacity.
This unit performs routing and switching. It can understand the
prefixes. SNU is skirt N/W unit and CNU is the main central N/W unit.
NCC performs N/W communication control and BDR is the BUS driver for
the interface of this module.
Central Processing Module performs various important
tasks related to call processing. It performs alarm monitoring and processing, ticket
generation for the calls, duration calculation,
billing and routing etc.Service processing module provides a
variety of interfaces like R2
No.5 and implements SS7 system, provides signaling path.
MHI
Multi highway interface is a part
of LIM and provides 2M & 8M
HW
Shared resource module provides DTMF, MFC, Conference Telephone and FSK display device services.SPD is signal tone while SRC is shared resource card.

Work Station contains a software program that is used to configure boards, monitor
alarms, analyze traffic statistics, access the data at
BAM storage media and perform several other useful
tasks.
