IDM M9000C Vehicle-mounted Communication Command & Dispatch System

I. Overview

The IDM M9000C vehicle-mounted communication command dispatch system employs advanced digital signal processing technology and large-scale integrated circuit technology to connect wireless communication terminals of different frequencies, standards, and types onto a single voice platform, achieving interoperability among disparate wireless communication systems. It can also connect to the fixed telephone network, cellular mobile communication network, Internet (IP) network, wireless LAN, as well as trunked mobile communication systems and satellite communication systems.

The IDM M9000C vehicle-mounted communication command dispatch system is a voice dispatch system suitable for group command, featuring dedicated command, group command, skip-level command, and conference command functions. It can also be extended to support multiple digital signaling standards of telephone exchanges and provides a variety of narrowband and broadband voice/data interface capabilities.

The IDM M9000C vehicle-mounted communication command dispatch system can be used for air defense position command in combat, training exercises, counter-terrorism and stability maintenance, as well as emergency rescue and disaster relief. It can provide an emergency interoperability platform supporting vehicle-mounted, fixed, portable, and mobile communication modes during natural disasters or emergencies. It also rapidly provides a collaborative voice platform for emergency interoperability communication systems encompassing public and private, wired and wireless, cross-regional, and cross-departmental communications.

V. Operating Modes

5.1 Basic Operating Modes

1. Multi-party conference mode: Intercom with ordinary telephone sets adopts the multi-party conference mode, i.e., one conference number is configured for each VHF radio, and all telephones monitoring that radio can dial in to enter the conference room. Within the conference room, the voice of any party (including both radios and telephones) will be sent to other telephones and can also be sent to the VHF radio. The continuous transmission time of the VHF radio is limited to 2 minutes. Due to the limited capacity of the conference room, the number of telephone terminals that can freely converse is limited. However, additional receive-only terminals can also be added at this time.

2. Ordinary telephone intercom mode: In this mode, there is no limit on the number of telephones joining a VHF intercom session. After dialing the VHF access number, a telephone can monitor the radio's voice. To speak to the radio, the user needs to press the flash key on the telephone or tap the switch hook to obtain 20 seconds of speaking rights (20 seconds by default, configurable via system settings). To prevent contention among multiple users, the telephone that has obtained speaking rights emits a prompt tone.

3. PTT terminal intercom mode: In this mode, terminals are normally in the radio monitoring state. When a user needs to speak, they press the PTT key (ordinary telephones require a PTT adapter; our company provides telephones with PTT function switching). The speaking duration is determined by the terminal!

4. Broadcast mode: The VHF radio audio is broadcast one-way to each telephone that has joined the monitoring group. Terminals only receive VHF audio. This mode does not limit the number of telephones listening to each VHF voice channel.

Note:

In actual use, mode 4 can be combined with the other three modes.

a) Multiple VHF radios can be operated in parallel by bridging 2 or more radios into the same conference room. Voice received by one radio can be forwarded to other radios or telephone terminals;

b) A single telephone can join monitoring of multiple VHF radios, and its speech can be transmitted to multiple radios simultaneously.

5.2 Wireless Channel Access Control Modes

1. PTT control mode: Audio interfaces with PTT function shall prioritize PTT control mode when interfacing with radio transceivers and trunked radio systems.

2. DSP volume control mode: Some audio terminals do not have PTT function (e.g., conference microphones). In this case, the sound level is dynamically monitored, and the receive/transmit state of the wireless interface is controlled based on the sound level.

3. DTMF telephone keypad control mode: Telephones and mobile phones can send commands to the dispatch switch via the DTMF keypad to control the receive/transmit state of the wireless interface.

Note 1: Each wireless interface can select one control mode.

Note 2: Mobile phones or external landline phones can dial *02 to access a 2-channel radio. After pressing the # key to speak, the user obtains 15 seconds of speaking rights (system-configurable). To exit, dial [*#] or [*3302].

VI. IDM-MCC10 Portable Dispatch Console

Basic functions: Click-to-call, call transfer, call forwarding, call parking, call pickup, call preemption, hold/resume, do-not-disturb, call blocking, night and holiday service policy configuration, etc.

Dispatch functions: Barge-in, forced disconnect, call takeover, monitoring, call barring, manual/automatic transfer, group call, group paging, conferencing, dynamic grouping, hierarchical collaborative dispatch, etc.

Broadcast functions: Includes broadcast, public address, and environmental monitoring functions. Broadcast includes instant broadcast and scheduled broadcast. Broadcast audio sources can be selected from internal sound files, external audio sources, or TTS files for playback.

Trunked radio intercom: Can dispatch intercom radios of different frequency bands, different models, and different standards (digital/analog); talk rights can be controlled through the dispatch software interface.

Conference functions: Conference initiation, conference scheduling, conference member identity authentication, multiple simultaneous conferences, conference process monitoring, etc.

SMS functions: Can send SMS messages to internal IP phones, Wi-Fi phones, multimedia terminals, and GPS terminals by click, and can also send SMS messages to external mobile network phones.

Electronic fax: Import fax files, batch sending, and after receiving faxes, save images and automatically send them to designated email addresses.

Emergency response plans: Supports communication emergency response plan management. Communication emergency response plans can be pre-edited according to the usage environment (e.g., flood control, drought relief, explosion, fire, etc.). When an event occurs, clicking the corresponding emergency plan button on the dispatch console can quickly initiate pre-configured communication dispatch operations (e.g., automatic public address broadcast alarm, automatic initiation of conferences with the responsible personnel, automatic sending of event notification SMS messages).

Monitoring functions: Missed calls, unregistered devices, and call queue status are all displayed; communication fault alarms and fault log management.

System management: Group management, account management, multi-level permission management, and hotline management.
