PCM

Overview:

The IDM-MINI8 Integrated Service Multiplexer is an integrated multiplexing transmission device developed by our company. It transmits N*64K data services over E1 or fiber transmission channels while simultaneously supporting the transmission of 8 channels of 64K voice and data services.

The IDM-MINI8 Integrated Service Multiplexer adopts a standalone structure, capable of converting 10/100Base-T Ethernet, voice, V.35, V.24 and other services into E1 data streams for transmission over E1 or fiber channels. It is suitable for extending interface working distances and expanding service coverage through channels such as fiber, microwave, and DDN private networks.
