IDM-RG2000 SIP Radio Gateway

**IDM-RG2000 SIP Radio Gateway**

# I. Overview The IDM RG2000 Softswitch Trunking Dispatch Gateway provides connections for up to three base station radios. Each radio has a dedicated SIP voice channel connected to the [dispatcher](/product/) as a hotline, plus 1~2 additional SIP voice channels that can be switched to any radio at any time. When a base station radio has multiple voice channels simultaneously, a voice conference room is formed between the radio and the multiple voice channels. The gateway supports the [dispatch console](/product/) specifying a radio's operating frequency, transmitted via the standard MQTT IoT protocol, and then changing the radio channel's operating frequency through voice or digital means. The trunking dispatch intercom gateway registers simultaneously with the SIP voice dispatch server and the IoT communication server. It supports the SIP softswitch protocol and the IoT MQTT protocol. The MQTT protocol supports PTT command transmission, serial port radio frequency management, radio power settings, etc. On the [dispatch console](/product/) interface, the station name, radio purpose name, radio model, radio frequency, and the SIP dedicated line telephone number are displayed. The [dispatch console](/product/) icons also show the radio's transmit/receive status, audio on the SIP dedicated line, etc. The IDM RG2000 SIP VHF trunking radio gateway provides audio interfaces for three VHF radios and serial interfaces for radio parameter control. There are 5 SIP telephone links that can connect to other SIP terminals through the dispatch server. Each radio has a corresponding voice conference room, supporting up to 6-party conferences, meaning one radio can allow 5 SIP telephone clients to speak online simultaneously. # II.

# II. Panel Interfaces Power interface, indicator lights. (Power input 220V) Ø Management interface: RJ45 interface; Ø Radio interface: RJ45 interface; 1~3 Ø Telephone interface: RJ45 interface; Ø Network interface: NET1~NET2; The LED lights on the device panel provide status alarms, making it easy to understand whether the device is working normally or in an alarm state. The panel indicator definitions are as follows:

**Table 1 IDM-RG2000 Indicator Description**

Name	Color	Function	Description
PWR	Green	Power indicator	Lights up when system power is normal; turns off when power supply is abnormal.
ACT	Green	Device operation indicator	Blinks at 250ms intervals when the device CPU is working normally; stays on or off when abnormal.
STU	Green, Red	Status indicator	Red light stays on when WAN port fails to obtain an IP address, possibly due to no network cable connected, DHCP address acquisition failure, IP address conflict, PPPoE dialing failure, etc.; alternates red and green when connection is normal;
WAN	Green	WAN port indicator	Stays on when WAN connection is established but no traffic; blinks when WAN connection is established and traffic is present.
PC	Green	PC port indicator	Stays on when link is up but no traffic; blinks when traffic is being transmitted; turns off when link is down.
WORK	Green	WORK indicator	Blinks when device is operating normally;
CALL	Green	CALL indicator	Blinks when device is operating normally;
1	Green	Channel audio indicator	Lights up when there is audio on the radio channel; turns off when no audio.
2	Green	Channel audio indicator	Lights up when there is audio on the radio channel; turns off when no audio.
3	Green	Channel audio indicator	Lights up when there is audio on the radio channel; turns off when no audio.
4	Green	Channel audio indicator	Lights up when there is audio on the radio channel; turns off when no audio.
5	Green	Channel audio indicator	Lights up when there is audio on the radio channel; turns off when no audio.
