  1. System Overview
  1. General Description

SAU-01A/SAU-02A/SAU-03A/SAU-02B digital user loop equipment is developed and manufactured through board software development and based on part of access equipment, it is a new type of user loop equipment.

The equipment is connected with transmission equipment through 2M interfaces, and conducting communication between local end and remote end through optical transmission platform. The equipment provides multiple service interfaces, and suits for many application fields.

The equipment communicates with Element Management Unit (EMU) of network management system through MBUS interface on backboard, and unitedly managed over optical transmission supervision system.

The equipment provides Common Channel Signaling software and Channel Associated signaling software so that connection with other equipment becomes more convenient, application arrange is expanded and succession strengthened.

SAU-01A/SAU-02A/SAU-03A/SAU-02B digital user loop equipment and DN1601 equipment, together with optical transmission series equipment of FiberHome can construct an integrated point-to-point network solution, which applies to telecommunication network, data communication network and other dedicated network of Telecom, Electric Power, Army and Railway Department, etc.

Equipment Structure

The equipment adopts standard 19” rack, composed of 19” sub-rack, backboard, and board. Access control board, cross-connect board, test board and power supply board have fixed location on the rack, while other SIF slots are available for different service interface boards. EMU board and network software will be configured to satisfy the request for network management system. Pay attention to the difference between the four types of equipments: SAU-01A is configured with a 7U board vertically-inserted structure, while SAU-02A a 5U board vertically-inserted structure, SAU-03A a 6U board vertically-inserted structure, SAU-02B a 2U horizontally-inserted structure.

  1. Board Structure

According to the dimension, board is divided into 5U board and 7U board, SAU-01A adopts 7U board, SAU-02A, SAU-03A and SAU-02B adopt 5U board.

According to the function, board is divided into control board, cross-connect board, test board, power board and service interface board with different configuration for each.

Access control board and cross-connect board consist of 2M access control board (AC2), 4E1 access control board (AC4), access control board (AC8), line concentration board (2CMUX) and 8E1 cross-connect board (8E1X), which are the core of control system, and responsible for centralized supervisory on services. Its location on the rack is fixed.

Test board (TST) is in charge of the test for user line, user terminal and user wire. Its location on the rack is relatively fixed.

Power board consists of power board and power ringing board, and only one is chosen to perform power conversion.

The position of service interface board is not fixed. Multiple service interface boards provide multiple service interfaces and fulfill various service access. Service interface board includes: subscriber-end voice interface board (SCH, SCHK), exchange-end voice interface board (ECH, ECHK), 2/4 wire audio-frequency interface board (2/4W), RS232 interface board (D232), bus RS232/485 interface board (232/485), 64K co-directional data interface board (D64), E/M interface board (EM), magnet interface board (RD), MOS interface board (MOS), Hi-fi voice interface board (HFi), V35 interface board (V.35), V.35/2M transit board  (V35), transparent U interface board (TU), G.SHDSL interface board (HDSL), ADSL interface board (ADSL) and etc.

In addition, equipment management can be fulfilled through EMU board of optical transmission system. In the case of no transmission system, EMU board and network management software need to be equipped for user request.

  1. Network Management System

SAU-01A/SAU-02A/SAU-03A/SAU-02B digital user loop equipment has three management interfaces: CORBA interface, F interface and f interface, three management platforms: UNIX, NT and f. There are special network management manual.

Equipment can be managed through f interface. The involved boards are linked as follows: SAU-02A is connected to the network management unit (EMU) of the network management system via the MBUS wire, and the EMU is connected to the control terminal (computer) via the f interface wire. The steps of configuring the control terminal are as follows: firstly configure the EMU, add sub-shelf by request, then equip different boards into the sub-shelf, lastly configure these boards.  

The equipment can also be managed by network management system of optical transmission platform (OTNM2000). OTNM2000 is a network management system, which is capable of effectively managing all types of transmission equipments and access equipments developed by FiberHome. The protocol employed accords with corresponding ITR-T recommendations and ISO standards as well as relevant national standards, industry standards and enterprise standards.

OTNM2000 adopts layered structure and modularized design, and the perfect system structure makes it possible to add and expand more management subjects conveniently. OTNM2000 performs high efficiency management over various transmission equipment and access equipment of FiberHome, and can unitedly manage the system composed of transmission equipment and access equipment in a network management platform, which is convenient for operation and can lower maintenance cost.

OTNM2000 adopts open system structure and object-oriented analysis, design and realization tool, so management layer is relatively independent and realizes object-oriented concurrent multi-task disposition, centralized sub-network management and remote supervision. Along with the user network expanding and upgrading, new user and new network element can be brought into the network management at any moment.

OTNM2000 is a network management system with powerful function, it has four management function of performance management, configuration management, fault management and security management, which can perform real-time supervisory and control. System provides reliable security mechanism, and user identity and password must be checked before the system is operated. In addition, system provides system management and remote management, which make it convenient for user to execute attribute setting and system maintaining on the foundation of the four management functions.
