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. Destination 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.
