IDM DXC5200 Multi-Service Cross-Connect Multiplexer

1 Overview

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

The IDM DXC5200 Multi-Service cross-connect multiplexer is fully equipped with 240 standard E1 transmission interfaces, adopting PCM30/31 system. It also features a non-blocking 64K timeslot cross-connect capability among the 240 E1s. Additionally, the DXC5200 timeslot cross-connect supports multiple clock modes to meet clock requirements in various application environments.

Critical modules of the IDM DXC5200 Multi-Service cross-connect multiplexer, such as the main control card and power supply card, adopt dual-card redundancy.

2 Features

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

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

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

u Main control card: Supports full cross-connect capacity of 7200×7200 64K timeslots, provides access and management of user interfaces, 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 function;

u E1 service card: Each card provides 24 E1 interfaces, connected via European-style connectors, and supports remote online upgrade function;

u Network management card: Supports online collection of TS16 signaling formats from third-party manufacturers through network management software and automatic saving. It can set signaling formats for any 64K timeslot among the 240 E1 channels, enabling telephone service interconnection and interworking with any manufacturer's PCM equipment;

u Test card: Configured with test ports, where test ports are set as FXS interfaces. Using the network management system, the test port can perform tests on specified 64K timeslots, such as sending ringing current, sending audio, receiving audio, three-way calling, two-way calling, monitoring, and 64K timeslot bidirectional loopback.

u The device also supports plugging in 64K and N*64K service cards. The service types and quantities can be arbitrarily configured within the chassis, with each slot capable of providing 16 channels of 64K services, supporting FXS/FXO, magneto, 2/4-wire EM, RS232/RS422/RS485, GSM/CDMA services.
