8Switching Module:Independent switching function and handles traffic intra moduleProvides various services interfacePerforms a variety of functions including database management, call processing, ,maintenance and operation.
9Remote Switching Module: Same as SM, difference is that SM links through 40 meter optical interface while RSM has standard E1 interface and may use SDH, specifically STM-1.
10FRONT ADMINISTRATION MODULE Management of inter-sim call connection.Provides open management interface to terminal system.It performs routine management tasks like ticket recording and traffic statistics.
11COMMUNICATION MODULEIt consists of central switching network and inter-module communication interface.Also provides inter SM speech channels and signaling links.
12BACK ADMINISTRATION MDULE It deals O&M open terminal network that is based on TCP/IP protocol.All the database and programs are stored on BAM storage blocks.
13SERVICE PROCESSING MODULE Connected with BAM directly using 10/100Mbs TCP/IP interface.Works with the interface of SDH(STM-1) and E1 to provide interfaces of trunks and AN.
14SHARED RESOURCE MODULE It provides all the resources required by all the SPMs in the whole office.The services include:DTMF deviceSignal TonesConference telephone deviceCID display device.
17RACK # 11This rack contains BAM and works as a server to control all the features and configurations of the workstation in the exchange including C4, C5 and HCTE.Every new card or rack configuration is carried through it.It consists of:2 LAN switches (Quidway S3026).KVMS for key board mouse and monitor screen.Switch panel to switch over to different workstations and display their configuration onto the screen.5 hard disk modules each having a capacity of 36.4 GB.A frame for IGWB (integrated gateway billing.)
19RACK # 0This rack is concerned with utilization of power to all of the racks and frames of HCTE.It is called PDF (power distribution frame).It contains switches and circuit breakers.
20RACK # 1 RSP Card: It contains HDSL modems. Lower frame has power PWX and the following two cards:ASL Card:It is for console telephone and 16 subscribers capacity to be linked to it.RSP Card:It enables any E1 frame for above mentioned console to make a call.
22RACK # 4 it is also called LIM, line interface module. One frame contains 0 to 25 slots. 1st and last are available for power.it is also called LIM, line interface module.Frame # 11 is empty.Frame no 8, 9 and 10 contain the following:ET16: electrical interface for 16 E1s.STU: optical interface for 63 E1s.QSI: used for internal communication
23RACK # 5It is same as Rack #4 but it has frame #7 empty.
24RACK # 6 It is called communication control module. It contains central clock module used for synchronization of signals. Frame 2 is called FAM.Frame 3 contains:PWS: for power supply to frameSNU: for switchingBDR: bus driverFrame 1 contains CPC where one CPC contains four SS7 links.
25RACK # 7Frame no 19 is empty.Frame no 18 is SRM (shared resource module) which is used for announcements etc and has dual power.Frame no 16 is MHI (media highway interface) used for interfacing the whole of the exchange patching it with backbone.
26RACK # 8It contains all the CPC signaling consoles and frame no 24 and 25 are CPC signaling related.
27RACK NO 9 IS SAME AS RACK NO 8. RACK NO 1O IS MISSING.RACK NO 11 IS DISCUSSED EALRIER.
