       Product Overview

The IDM DXC5000 time slot crossover device is one of the PCM time slot crossover devices designed by our company using dedicated large-scale integrated circuits. Connect between user terminal devices or between user terminal devices and the public switched telephone network through a 2M transmission medium.

This device can utilize 8 standard E1 transmission channels (G.703 standard), adopt PCM30/31 standard, and directly provide various user interfaces such as voice, data, and image. Simultaneously, it has time slot non blocking cross connection devices between 8 sets of E1 and all user interfaces. At the same time, the device has multiple clock modes, which can meet the clock requirements of various application environments.

The number of 240 voice interfaces can be expanded through 8 E1 interfaces on the main control panel, and key units can adopt dual disk mutual backup.
