This presentation describes the working functionality of HCTE (C&C08). It fully details the process of call establishment and signaling paths through HCTE. RACK MODULE FRAME BOARD MODULES FRAMES RACKS PERFORMS COMMUNICATION b/w MPU AND BOARDS IN USER AND TRUNK FRAMES. INTEROFFICE DIGITAL TRUNK INTERFACE, 16 DTF = 960 CHANNELS AND 1 DTF = 2 PCM DT NOD PERFORMS EQUIPMENT CONTROL, RECIEVES ASL AND TRUNK STATE THROUGH NOD BOARD AND SEND CORRESPONDING COMMANDS TO THEM. CONTROLS THE SIGNALS OF SIG BOARD (DIAL TONE, VOICE SIGNALS). ANALYZE THE CALLED AND CALLING PARTIES TO HELP OUT SWITCHING FOR THE NOS OF SAME SM. MPU SIG DT DT 2 ASL CARD DRV BNET 32 ANALOG SUBSCRIBERS “BORSCHT” FUNCTION RECEIVES DTMF SIGNALS, DRIVES HW SIGNALS AND SENDS PORT SIGNALS INTRA-MODULE SWITCHING NETWORK BOARD, 4K X 4K SWITCHING NETWORK Speech path 40.96 Mbps OPTICAL INTERFACE TO OBC BOARD OF AM/CM OF HCTE. IT’S A PHYSICAL TERMINATION CARD. OPT 1 Signaling path CNET NCC SNU 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. CNU BDR 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. High Speed 393M Optical Interface Destination OBC SM ALARM QSI 16 E1s ET-16 Shared resource module STU provides DTMF, MFC, 63 STM-1 Conference Telephone and FSK display device services. SPD is signal 8Mbpstone while SRC is shared resource card. Communication control module that interlinks CPM, LIM,SPM and CNET through HDLC CCM HDLC CID DISPLAY 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. Service processing module provides a variety of interfaces like R2 No.5 andCDP implements SS7 system, provides signaling path. Multi highway interface is a part of LIM and provides 2M & 8M HDLC 2Mbps HW MHI BAM AMP Centralized clock synchronization to SERIAL LINK the whole RS-232 exchange. CPM 10 Mbps TCP/IP 2.048Mbps 2.048KHz 8KHz SPC 8KHz 2.048Mbps SPD SRC BUS control process board. Used for BUS SERIAL LINK communication Admin RS-232and b/w AMP and TCP/IP CDP. maintenance processing and online data Central Processing Module setting. performs various important tasks related to call processing. It performs alarmprocessing monitoring and Central database processing, 10Mbps and management of common ticket generation for the calls, resources. duration calculation, Deals location selection of PBX, billing and routing etc. trunk line etc. BCP BAC FSN CPC SRM Alarm board for all system alarm processing. HDLC interface board that interconnects LIM,CNET and CCM. Provides Speech and Signaling path. LIM Work Station contains a software program that is used to configure boards, monitor alarms, analyze traffic WORK STATION statistics, access the data at BAM storage media and perform several other useful tasks.
