IDM Integrated Multiplexer

Overview
The IDM Integrated Multiplexer is a compact portable multimedia dispatch switch that integrates multiple communication methods including SDH communication, mobile phone communication, radio communication, subscriber telephone (FXS), and loop trunk (FXO). Through advanced digital voice processing technology and network encryption transmission technology, it enables seamless access of devices such as two-way radios of different frequency bands, VHF/UHF radios, HF radios, traditional PSTN telephones (Public Switched Telephone Network), IP softphones, and traditional IP phones into the dispatch system network. It can be used independently, paired with a dispatch console, or deployed as a remote trunking access gateway for a large dispatch system. It not only enables long-distance wireless two-way radio communication but also provides full-duplex voice interworking between wireless devices and wired terminals, effectively resolving challenges in wireless communication network interworking, dispatch, management, and large-scale networked dispatch. It is suitable for multi-communication integration in environments such as border posts, vehicles, and ships, and can be conveniently integrated into existing dispatch systems for long-distance large-scale wireless networked communication.
The IDM Integrated Multiplexer employs all-digital information processing technology with performance superior to relevant national standards. It supports both traditional PSTN telephone interfaces and IP telephony based on SIP standard protocol and H.323 protocol. It offers strong flexible configuration capability and is suitable for a wide range of application environments. It adopts a 19-inch 3U desktop structure design.

Typical Device Configuration

The IDM Integrated Multiplexer can connect up to 12 wireless radio devices, including HF (shortwave), VHF (ultra-shortwave) single-sideband radios, 350M and 800M trunking two-way radios, etc.
The trunk interfaces of the device can be:

1. GSM/CDMA interfaces;
2. WAN port supporting electrical interface (RJ45) or optical interface (FC) (as access channel for IP phones);
3. Ordinary telephone trunk interfaces;
4. Ordinary magneto interfaces or 2100Hz magneto interfaces;
   The default number of interfaces for connecting ordinary telephones or wired intercom terminals is 20 channels (10 channels per module).

Functional Description

1. All wired intercom terminals can intercommunicate with each other;
2. All wired intercom terminals and telephones can select any one or more wireless trunking groups for monitoring and speaking;
3. Extensions can make external calls through ordinary telephone interfaces, GSM/CDMA, IP trunk, etc.;
4. Any two or more wireless radios or trunking systems can be bridged.
5. Supports group call function. When an external call comes in, all telephone extensions in the same group call group ring simultaneously. When any extension goes off-hook, the others stop ringing. If more than 2 external calls come in simultaneously, when any telephone goes off-hook, the external call with higher priority is connected first, while other extensions continue ringing;
6. Simultaneous incoming external calls are always answered according to priority, and calls with equal priority are answered in order of ringing sequence.
7. Generally, wired intercom terminals have higher priority than internal telephones. Users with higher priority can interrupt the trunking transmission rights of lower-priority users.
