1 1 VENDORS: C&C08 RACKS ALIGNMENT:0 TO 11 RACKS MISSING:2,3 & 10 FRAME ALIGNMENT: RACK #1 HAS 6 FRAMES RACK 4-9 HAVE 4 FRAMES.

2 2 PROFILE C&C08

3 3

4 4 MODULES  CM: Communication Module  AM: Administration Module  FAM: Front AM  BAM: Back AM  SPM: Service Processing Module  SRM: Shared Resource Module  SM: Switching Module

5 5 OVERALL STRUCTURE

6 6 MODULAR DESIGN

7 7

8 8 Switching Module:  Independent switching function and handles traffic intra module  Provides various services interface  Performs a variety of functions including database management, call processing,,maintenance and operation.

9 9 Remote 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.

10 10 FRONT 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.

11 11 COMMUNICATION MODULE  It consists of central switching network and inter-module communication interface.  Also provides inter SM speech channels and signaling links.

12 12 BACK 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.

13 13 SERVICE 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.

14 14 SHARED RESOURCE MODULE  It provides all the resources required by all the SPMs in the whole office.  The services include: DTMF device Signal Tones Conference telephone device CID display device.

15 15 TERMINAL SYSTEM OF C&C08:

16 16

17 17 RACK # 11  This 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: 1.2 LAN switches (Quidway S3026). 2.KVMS for key board mouse and monitor screen. 3.Switch panel to switch over to different workstations and display their configuration onto the screen. 4.5 hard disk modules each having a capacity of 36.4 GB. 5.A frame for IGWB (integrated gateway billing.)

18 18 Continue…

19 19 RACK # 0  This 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.

20 20 RACK # 1  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.

21 21  RACK NO 2 AND RACK NO 3 ARE MISSING !

22 22 RACK # 4  One frame contains 0 to 25 slots. 1 st 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

23 23 RACK # 5  It is same as Rack #4 but it has frame #7 empty.

24 24 RACK # 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 frame SNU: for switching BDR: bus driver  Frame 1 contains CPC where one CPC contains four SS7 links.

25 25 RACK # 7  Frame 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.

26 26 RACK # 8  It contains all the CPC signaling consoles and frame no 24 and 25 are CPC signaling related.

27 27  RACK NO 9 IS SAME AS RACK NO 8.  RACK NO 1O IS MISSING.  RACK NO 11 IS DISCUSSED EALRIER.

28 28 PHYSICAL CHARACTERISTICS  C&C08 has: 100,000 trunk switch 9 racks  Power Consumption: Normal 3060W busy hour 5240W. Formula for load analysis: P=V*I P: power, V=-48V, I: find on rectifier display.  Tepmerature: Long term; 0-45 C Short term; 0-55 C
