IDM-M2000 Mobile Multimedia Dispatch Console

I. Overview

The IDM-M2000 is a compact portable multimedia dispatch console that integrates multiple communication methods including 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 standalone, or with a dispatch console, or 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, conveniently solving the difficulties in interworking, dispatching, management, and large-scale networked dispatching of wireless communication networks. It is suitable for the integration of multiple communication methods in environments such as border posts, vehicles, and ships, and can also be easily connected to existing dispatch systems for long-distance large-scale wireless networked communication.

The IDM-M2000 adopts all-digital information processing technology, with performance superior to relevant national standards. It supports both traditional PSTN telephone interfaces and IP phones with SIP standard protocol and H.323 protocol. It offers strong flexible configuration capability and is applicable to a wide range of environments. It adopts a 19-inch 1U desktop structure design.

II. Device Configuration:

The IDM-M2000 can connect up to 4 radio transceiver units, 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 (up to 2 channels);
   

2.     WAN port supports electrical interface (RJ45) or optical interface (FC) (as the access channel for IP phones, up to 2 IP phones can be connected);
   

3.     Ordinary telephone trunk interfaces (minimum 2 channels);
   

The number of interfaces for connecting ordinary telephones or wired intercom terminals is 4 or 8 channels (4 channels per module).

III. Function Description:

1.     Intercom can be achieved between all wired intercom terminals;
   

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 radio transceivers or trunking groups can be bridged.
   

Supports group call function. When an external line dials 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 lines call in simultaneously, when any telephone goes off-hook, the external line with higher priority is connected first, while other extensions continue ringing;

For simultaneously incoming external calls, they are always answered according to priority, and calls with the same priority are answered in order of ringing sequence.

Typically, wired intercom terminals have higher priority than internal telephones, and users with higher priority can interrupt the trunking transmission rights of lower-priority users.

5.     Supports [recording-to-text transcription](http://www.newrocktech.com/solutionss/1136.html)
   

6.     Provides traversal services for applications such as external network extension registration, branch networking, and mobile office
   

7.     IP phones are plug-and-play
   

8.     Can directly interface with operator IMS networks
   

9.     Provides open API interfaces for integration with third-party application systems
   

10. Supports multi-level voice navigation, intelligent duty, and mobile extensions
    

11. Supports IDM network management system and third-party network management systems (TR-069, SNMP)

IV. Application Examples:

A single unit can form a small-scale dispatching system for temporary emergency dispatch, playing a significant role in military emergency training, vehicle-mounted command systems, border sentry posts, and temporary field applications. Meanwhile, this dispatching system can be connected to a higher-level dispatching system.

This dispatching system can be deployed on a mobile emergency communication vehicle, used in conjunction with our portable dispatch console to form a mobile command center, capable of interfacing with mobile phones, radio stations, shortwave radios, and various other terminals, greatly improving on-site command efficiency.

In large-scale dispatching systems, this device can be used in conjunction with the central dispatch switch (PBX/IPPBX) as a remote trunking gateway, enabling dispatching functions for various media terminals such as remote trunking radios, shortwave radios, WIFI terminals, and mobile phones.
