IDM M9000 Portable Multimedia Dispatch System

Overview
The IDM-M9000 is a compact portable multimedia dispatch system that integrates multiple communication methods including SDH, cellular, radio, subscriber telephone (FXS), and loop trunk (FXO). Through advanced digital voice processing and network encryption transmission technologies, it enables seamless access of devices such as two-way radios on different frequency bands, VHF/UHF radios, HF radios, traditional PSTN telephones, IP softphones, and traditional IP phones into the dispatch system network. It can be used standalone, paired with a dispatch console, or deployed as a remote trunking access gateway for a larger dispatch system. It enables long-distance wireless two-way radio communication as well as full-duplex voice interworking between wireless devices and wired terminals, conveniently solving 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 easily integrated into existing dispatch systems for long-distance, large-scale wireless networked communication.
The IDM-M9000 employs all-digital information processing technology, with performance exceeding relevant national standards. It supports both traditional PSTN telephone interfaces and SIP standard protocol and H.323 protocol IP telephony. It offers strong flexible configuration capabilities and is suitable for a wide range of application environments. It features a 19-inch 3U desktop structure design.

Typical Device Configuration

The IDM-M9000 can connect up to 12 wireless radio devices, including HF (shortwave), VHF (ultra-shortwave) single-sideband radios, and 350M and 800M trunking two-way radios.
The device's trunk interfaces can be:

1. GSM/CDMA interfaces;
2. WAN ports supporting electrical interface (RJ45) or optical interface (FC) (as access channels for IP telephony);
3. Standard telephone trunk interfaces;
4. Standard magneto interfaces or 2100Hz magneto interfaces;
   The default number of interfaces for connecting standard 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 place external calls via standard telephone interfaces, GSM/CDMA, IP trunking, etc.;
4. Any two or more wireless radios or trunking systems can be bridged together.
5. Supports group call function: when an external call comes in, all telephone extensions in the same group call group ring simultaneously, and when any extension answers, the others stop ringing. If more than 2 external calls come in simultaneously, when any telephone answers, 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, and users with higher priority can interrupt the trunking transmission rights of lower-priority users.
