Profile of C&C08 Length: 2100 mm Width: 800 mm Depth: 550 mm Maximal Capacity : 800,000 subscriber lines or 180,000 DT Local, Tandem, Toll, International Exchanges Four Parts of C&C08 LAN Switch, Display ,Converter and Server. Eight HCTE in Bahawalpur, Multan, Lahore, Karachi, Gujranwala, Faisalabad, Peshawar and Islamabad. 8. 8 Structure of Connectivity 9. 9 C&C08 Main Modules Description Front AM (FAM) It manage the inter SIM call connection and interfaces of terminal system like ticket recording and traffic statistics. Back AM (BAM) It deals O&M open terminal network that is based on TCP/IP protocol. It is stored all the databases and programs also. Integrated GateWay for Billing (IGWB) It is used to save the billing data. 10. 10 C&C08 Main Modules Description Switching Module It is Independent Switching function, handles traffic intra modules; provide various services interface; perform functions like database management, call processing , maintenance and operation. 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, especially STM-1. 11. 11 Main Logical Module In C&C08 Service Processing Module Connected with BAM directly using 10/100Mbs TCP/IP interface and works with the interface of SDH (STM-1) and E1 to provide interfaces of trunks and AM. Shared Resources Module It provides DTMF devices, Signal Tones, Conference telephone device and CID display device required by all the SPMs in the whole office. 12. 12 Main Logical Module In C&C08 ClocK Module (CKM) Communication Control Module (CCM) Central Processing Module(CPM) Line Interface Module (LIM) Media Highway Interface (MHI) Communication Module (CM) Communication Network Unit (CNU) Switching Network Unit (SNU) 13. 13 Hardware Description ET16 (Electrical Transmission ) It is electrical Interface. It provide 16 E1s. Synchronous Transfer Unit (STU) It is optical interface. It provide Synchronous Transfer Module (STM-1 ( 63 E1s)). QSI It is used for internal Communication. It collect data from ET16 and STU, communicate in the switch(HCTE C&C08) PoWer Controller (PWC) It provide DC power to semi frame. There are two PWC boards are used in the frame. It give 5,12,24 and 48 Volts to different boards. 14. 14 Hardware Description Media Highway Interface(MHI) It is used as bus to deliver control signal in the whole switch(HCTE C&C08). Communication Module (CM) It is main module which control the exchange. It is further divided into two section. CNU It is communication/control Network Unit. SNU It is switching network unit. ALarm Module(ALM) It generate alarm. 15. 15 Hardware Description Central Processing Card(CPC) It is used to provide signaling Links. One card can provide four signal link. One signal Link can handle 4096 channels. Service Processing Card (SPC) It is main card of SPM. It is used in pair master and slave. It can configure 128 E1s. SPD It is main card of SRM. It provide DTMF(Dual Tone Multi Frequency). Bus DriveR(BDR) It provide buses for communication of signals. 16. 16 Hardware Description SPT It is also part of SRM. It provide announcements. ClocK Synchronization(CKS) It generate clock pulse. It is part of CKM. ClocK Digital(CKD) It is used to synchronize the clock in E1s as time slot-0. Fast Switching Network(FSN) It is used for Switching Purpose. PWX ( Power Distributor) It is used to distribute/Control the power. 17. 17 Hardware Description Back Address Controller(BAC) It is used as communication controller. It is main board of CCM. Analog Subscriber Line(ASL) It is subscriber Card. Its capacity of 16 subscribers. Remote Switching Processor(RSP) Its main function to communicate between SM and LIM Frame (ET16 card). 18. 18 Prepared by: Hafiz Shehbaz Ali For any query Contact: +923136585701 Email: Shehbaz.bsee1395@iiu.edu.pk International Islamic University Islamabad Supervised by: Engr.
