IDM-MINI PCM Integrated Service Multiplexing Equipment
The IDM-MINI Integrated Service Multiplexing Equipment adopts an independent structure, enabling the simultaneous transmission of 8+1 channels of 64K or n×64K voice and data services over a single E1 or fiber transmission channel. By converting 10Base-T Ethernet, voice circuits, V.35, V.24, and other services into E1 data streams, it supports transmission over E1 or fiber channels. It is suitable for extending interface working distances via fiber, microwave, or dedicated DDN networks, and can also function as a Telephone Optical Terminal. It can be combined with other series of multiplexing equipment to form various network topologies such as chain, star, and tree networks.

The IDM-MINI Integrated Service Multiplexing Equipment adopts an independent structure, enabling the simultaneous transmission of 8+1 channels of 64K or n×64K voice and data services over a single E1 or fiber transmission channel.

It can be combined with other series of multiplexing equipment to form various network topologies such as chain, star, and tree networks.
The IDM-MINIO version upgrades the E1 transmission to fiber transmission, making it ideal for voice and data access over private network-owned fiber lines. The IDM-MINI Centralized model supports up to 10 user plug-in boards, each corresponding to the service types supported by the IDM-MINI board-level model.
