PCM

Overview:

The IDM-MINI Integrated Service Multiplexer adopts an independent structure, capable of simultaneously transmitting 8+1 channels of 64K or n×64K voice and data services over one E1 or optical fiber transmission channel. By converting 10Base-T Ethernet, voice channels, V.35, V.24 and other services into E1 data streams, it enables transmission over E1 channels or fiber optic channels. It is suitable for extending the working distance of interfaces via channels such as fiber optics, microwave, and DDN private networks, and can also serve as a telephone optical terminal. It can be combined with other series of multiplexers to form various network topologies, such as chain networks, star networks, tree networks, and other integrated networks.

The IDM-MINIO, based on the IDM-MINI, converts E1 transmission to fiber optic transmission, making it suitable for voice and data access over self-provided fiber optic line channels in private networks. The IDM-MINI centralized version can be configured with 10 user interface cards, each supporting services corresponding to the IDM-MINI single-board version.

Product Features:

• E1 transmission and optical transmission options available;
• Over 20 types of service interface cards for flexible configuration;
• Can be networked with IDM series products for combined applications;
• Provides powerful audible and visual alarm indication for line operation status;
• Rich user interfaces, providing 8 channels of 64K voice, data, and 1 channel of N*64K service access;
