I. Overview

The IDM DXC8E1 Digital Cross-Connect Equipment is an integrated service platform that combines 64K narrowband service access, PCM multiplexing, and 64K timeslot cross-connect functionality.

The IDM DXC8E1 is primarily used for service access and cross-connection at the access layer of data communication networks. It features complete synchronization and timing functions, providing non-blocking 64K-level cross-connection across 8 E1 channels, while also supporting up to 30 channels of 64K services, including telephone, magneto telephone, common battery telephone, and V.24 data services.

II. Product Features

Ø Non-blocking cross-connection of all timeslots across 8 E1 groups;

Ø The main unit provides 30 channels of 64K (or Nx64K) user narrowband service access;

Ø The main board provides 15 service card slots, with each card supporting up to two service channels;

Ø Voice interfaces can be FXO central office automatic telephone, FXS remote automatic telephone, or MAG magneto telephone; data services include V.24/RS232/RS485/RS422, X.50/X.58, same-direction 64K, Nx64K bandwidth V.35/V.36, and Ethernet bridge;

Ø Supports serial port network management or Ethernet SNMP network management;

Ø Supports AC 220V power supply or DC -48V power supply;

Ø 8 E1 groups can form point-to-point, chain network, star network, and other topologies.
