IDM M9000 Portable Multimedia Dispatching Console

Overview
The IDM-M9000 is a compact portable multimedia dispatch console 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, devices such as two-way radios on different frequency bands, ultra-short wave radios, short wave radios, traditional PSTN telephones (Public Switched Telephone Network), IP softphones, and traditional IP phones can be seamlessly connected to the dispatch system network. It can be used standalone, paired with a dispatch console, or deployed as a remote trunking access gateway for a large dispatch system. It enables long-distance wireless two-way radio communication as well as full-duplex voice interworking between wireless devices and wired terminals, effectively resolving challenges in wireless communication network interworking, dispatch, management, and large-scale networked dispatching. It is suitable for environments such as border posts, vehicles, and ships requiring the integration of multiple communication methods, and can also be conveniently connected to existing dispatch systems for long-distance, large-scale wireless networking 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 phones. It offers strong flexible configuration capabilities and is suitable for a wide range of application environments. It adopts a 19-inch 3U desktop structure design.

Typical Device Configuration

The IDM-M9000 can connect up to 12 wireless radio devices, including HF (short wave), VHF (ultra-short wave) 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 phones);
3. Ordinary telephone trunk interfaces;
4. Ordinary magneto interfaces or 2100Hz magneto interfaces;
   The device provides a default of 20 interfaces for connecting ordinary telephones or wired intercom terminals (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 multiple wireless trunking groups for monitoring and speaking;
3. Extensions can make external calls via ordinary telephone interfaces, GSM/CDMA, IP trunk, etc.;
4. Any two or more wireless radios or trunking groups 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, and 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, and users with higher priority can interrupt the trunking transmission rights of lower-priority users.
