PCM Equipment IDM MUX8 Integrated Service Multiplexer

I. Overview

The IDM MUX8 Integrated Service Multiplexer is an integrated multiplexing transmission equipment developed by our company. It transmits N×64K data services over the E1 transmission channel while simultaneously supporting 8 channels of 64K voice and data services.

The IDM-MINI8 adopts a standalone structure, which can convert 10/100Base-T Ethernet, voice, V.35, V.24 and other services into E1 data streams for transmission over E1 channels. It is suitable for extending the working distance of interfaces through microwave, DDN private network and other channels, thereby expanding the service coverage.
