IDM DXC5200 Timeslot Cross-Connect Equipment

1. Overview

The IDM DXC5200 timeslot cross-connect equipment is one of the timeslot cross-connect devices designed by our company using dedicated large-scale integrated circuits. It completes the connection between user terminal equipment or between user terminal equipment and the public switched telephone network through 2M transmission media.

The IDM DXC5200 timeslot cross-connect is fully configured with 240 groups of standard E1 transmission interfaces, adopting the PCM30/31 format. It also features 240 groups of 64K timeslot non-blocking cross-connect between E1 interfaces. The DXC5200 timeslot cross-connect supports multiple clock modes to meet the clock requirements of various application environments.

Key modules of the IDM DXC5200 timeslot cross-connect, such as the main control board and power supply board, adopt dual-board mutual backup.

2. Product Features

u 19-inch 3U standard chassis, with 2 power supply board slots, 2 main control board slots, and 11 service board slots;

u Dual 48V power supply, supporting 1+1 redundancy protection;

u Dual main control, supporting 1+1 redundancy protection;

u Main control board: Supports a cross-connect capacity of 7200×7200 64K timeslots for full cross-connect, providing user interface access and management, data and signaling cross-connect, system synchronization, and device networking control and management; supports digital level adjustment for all E1 channels within a single-end device. The main control board supports remote online upgrade functionality;

u E1 service board: Each board provides 24 E1 interfaces, connected via European-style sockets, supporting remote online upgrade functionality;

u Network management board: Supports online collection of third-party manufacturer TS16 signaling formats through network management software, with automatic storage. Signaling formats can be set for any 64K timeslot among the 240 E1s, enabling interconnection of telephone services with PCM equipment from any manufacturer;

u Test board: Configured with test ports, which are set as FXS interfaces. Through network management, the test ports can be used to perform tests on designated 64K timeslots, including sending ring current, sending audio, receiving audio, three-party calls, two-way calls, monitoring, and 64K timeslot bidirectional loopback.

u The equipment also supports the insertion of 64K and N*64K service boards. The service types and quantities can be arbitrarily configured within the chassis. Each slot can provide 8 or 10 channels of 64K services, supporting FXS/FXO, magneto, 2/4-wire E&M, RS232/RS422/RS485, and GSM/CDMA services.
