24 THE STRUCTURE OF THE PSM Digital trunk unit DTI PCM1 PCM2 Provide 120 digital trunk subscribers for every board PCM3 PCM4 One DT unit only has one DTI board One DTI board has 4 PCM (sub-unit)

25 THE STRUCTURE OF THE PSM Analog signaling unit One Analog signaling unit only has one ASIG board. ASIG board can be configured as ---DTMF function ---MFC function ---TONE function ---CID function ---Conf. function

26 THE STRUCTURE OF THE PSM Switching Network Layer

27 THE STRUCTURE OF THE PSM Switching Network Unit DSN Work mode:active /standby DSN Unit Can Handle Time Slot Switching of the Voice Channel. And Control Message Channel Constitution:2 DSN boards

28 DIGITAL SWITCHING NETWORK Main Function: Performing Voice Channel Connection Switching of Subscribers Inside the Module; Interconnected With Central Switching Network Module to Realize Inter-module Voice Channel Connection; For Mp to Set up Message Switching Connection and Communication Via Semi-permanent Connections With Function Units;

29 HWS DISTRIBUTION OF DSN IN PSM Each DSN board has 64 HWS. A HW bus rate is 8Mb/s(128ts) Each DSN board has a capacity of 8K*8K time slots

30 HWS DISTRIBUTION IN PSM DSN Message communication Inter-module connection Self-looping testing Standby HW line Connected with various units

Function Used for Various Unit Connection Those Starting HW20 Upward Are Used for Connection With Subscriber Units. Each Subscriber Unit Seizes Two HW Lines; Those Starting Hw61 Downward Are Used for Connection With Digital Trunks and Analog Signaling Units. Each Unit Seizes One HW Line;

33 The Message Channel MP COMMCOMM DSNI C HW0 至 HW3 DSN SNM or other PSM function unit DSNI-S FBI

34 DSNI-C (DIGITAL SWITCHING NETWORK INTERFACE BOARD) Function: An interface of MP level (MP- DSN) It Drives the Various Signals Transmitted Between MP and DSN. It Performs the Conversion of 8mb/s Data Stream and 2mb/s Data Stream. A Pair of DSNI Boards Handle 4 HWs. MP--COMM--DSNI-C--DSN

35 DSNI-S (DIGITAL SWITCHING NETWORK INTERFACE BOARD) Function: It Drives Transmission Between Function Unit and DSN. No Data Rate Conversion A Pair of DSNI Boards Can Handle 16 HWs. SP--DSNI-S--DSN An interface of SP level (SP – DSN)

36 THE VOICE CHANNEL Suppose one subscriber in one SLU call another subscriber in another SLU,the voice channel will be as follows. SP---DSNI---DSN(T-network)---DSNI---SP

37 FBI (Fiber Bus Interface) It Applies Synchronous Multiplexing Technique and Optical Fiber Technique to Implement the Interconnections of Modules. It Uses Two Optical Fiber Lines to Transmit up to 16 Lines of 8mb/s PCM Signals It Can Reduce Connection Wires and Increase Anti- interference Ability of the System, and to Reduce Mutual Cross Talks Among Wires.

38 THE STRUCTURE OF THE PSM Clock synchronous part Retrieving the reference clock from the superior exchange(DTI or FBI),it provides synchronization timing signals SYCK CKI SYCK Working mode:Active/standby

55 MP NT Server TCP/IP protocol NT Client.. NT Client router DDN PSTN/PSPDN MP

56 The Network Contain 3 Types of Nodes: Foreground Active/standby MP Background Servers(server) Background Maintenance Terminal(clients) The structure of background network

57 MP (foreground ) connects with background by the Ethernet. It uses the HUB to connect each other. The communication protocol is TCP/IP. The operating system of Sever and Client is WINDOWS NT

58 The structure of background network Each MP and the computer in background have a IP address respectively. The arrangement is as follows: 1~128 identify the active/standby Mps of the 64 modules(MP nodes) 129~133are background NT Server nodes 134~187 are background Client nodes 254 is for the specific alarm panel.
