IDM MUX-3200 Broadband/Narrowband Integrated Service Multiplexing and Demultiplexing Equipment

I. Product Introduction

The IDM MUX-3200 is a modular integrated service multiplexing equipment housed in a 19-inch 3U chassis, designed for easy installation in equipment rooms or vehicles. Utilizing TDM multiplexing technology, it features low information latency and fixed transmission delay for data and voice. All access services occupy physically isolated independent channels, ensuring information security and confidentiality. It multiplexes various data, voice, video, network and other broadband and narrowband services into a single high-speed data stream (which can be E1, V.35 transmission bandwidth), then transmits bidirectionally via DDN leased lines, microwave, satellite and other communication links. It is easy to interface with secure communication equipment.

The IDM MUX-3200 trunk transmission interface can adopt either E1 interface or V.35 interface. The V.35 interface supports data rates up to 10Mbps, and with dual V.35 interfaces for mutual backup, it can be applied in high-reliability communication transmission environments.

Available service interfaces include transparent G.703 E1 interfaces, multiple physically isolated bridge interfaces, HDMI audio/video codec interfaces, synchronous/asynchronous EIA-232/EIA-422/EIA-429 interfaces, as well as telephone interfaces including FXO, FXS, standard magneto interface, 2100Hz magneto interface, and E&M 2-wire/4-wire audio interfaces.

The equipment features built-in hardware echo cancellation circuitry supporting G.168 protocol, capable of eliminating transmission delay echo within 800ms.

The product comes with a built-in service telephone dispatch system. Each unit provides 2 service telephone interfaces, supporting dialing between service telephones, as well as dispatch operations from the dispatch console including forced release, barge-in, and call transfer for service telephones.

It provides point-to-point bidirectional transmission of data, network, video, and voice, supporting bidirectional subscriber line provisioning.

It can be used for public security satellite communication, firefighting satellite communication, military satellite communication, microwave communication, etc. It is suitable for satellite communication vehicle and microwave communication vehicle retrofitting.
