RoIP Tetra Radio Gateway from Tetra Raido to VoIP

 Overview
RoIP Gateway is a voice gateway connecting radio and IP network. There are so many radio intercom systems, like: Analog Radio, TETRA Digital Radio, GOTA Digital Radio, etc, different radio intercom systems makes isolated information island, cannot achieve interconnection and interworking. .

A variety of radios with PSTN, IP phones, GSM/CDMA and other common communication networks are unable to achieve interconnection and interworking too.

In application areas such as emergency dispatching, isolated information island is the biggest obstacle to effectiveness. The integration of the radio intercom networks, traditional telephone communications network and NGN network is imperative. RoIP Gateway from NICEUC is designed to meet with such requirements, which supports 4 to 48 radio lines per unit.

Function
Each line interface of RoIP Gateway can be used as a terminal which registers to NGN SIP Server.

Radios can call the preset number of each line interface of RoIP Gateway via PTT button or DTMF dialing. This number can not only correspond to a terminal; but also can correspond to an intercom group and conference group.

Wired telephone call line number of RoIP Gateway then can be switched on connecting to the radio intercom devices which has same radio as line of RoIP Gateway.

Different standards of radios can be achieved interconnection and intercommunication through RoIP Gateway.

Support multi-level preemption rights of mix of wired and wireless.

When using the device, each line interface corresponds to a radio channel, so that you can access the same radio intercom systems to IP communication system.

A variety of standard digital radios and analog radios can be involved in IP communication system

Through other conversion gateways, radios with GSM/CDMA and other mobile networks can communicate with each other.

It has analog radio interfaces, TETRA digital radio interfaces or GOTA, etc., shortwave radio interfaces and other wireless radio interfaces.

 Specification of RoIP Gateway

 Application 1: Connection between Radios and IP phones (such as IP Dispatching system)

Description:

IP phones can dial the line number of RoIP Gateway which connected to radios, then attend the radio intercom.

IP phone can press "*1*" (or other definable function keys)to apply for right of calls, if the application is successful, RoIP Gateway will play a prompt tone "start to speak", and then IP phone can speak;

IP phone can press "*2*" (or other definable function keys) to release right of calls. After right of calls are released,

RoIP Gateway will play a prompt tone "start to listen", so the other terminal can apply for the right to speak

The TETRA terminal can directly press the PTT button for the right of calls and release the PTT button to release the right of calls.

When IP terminals occupy right of calls, other radio terminals with same radio can hear the content of the calls of IP terminal, and vice versa.

The application mode can realize the integration of wired dispatching and radio dispatching. At office with signals of radio, you can use IP phone to initiate intercom with radio system, and greatly expand the scope of dispatching to achieve seamless integration of wired system and radio system.

Application 2: Dispatching System in different places via RoIP Gateway

Description:

Break through the restriction of radio region, the dispatching center can realize the scheduling of radio systems in different places.

The dispatch center call number of RoIP Gateway in different places, it can establish intercom with remote radio users.

Application 3: Connection of Radios with different frequency or bands

Description:

RoIP Gateway from NICEUC has analog radio interfaces, TETRA digital radio interfaces or GOTA, etc., shortwave radio interfaces and other wireless radio interfaces.

According to the nature of accessing radios, we can perform customization access over RoIP Gateway, each line can be connected to different frequencies or bands of radios.

Dispatching system can dispatch radio systems with different frequencies or bands on basis of RoIP Gateway.

Application 4:  All-in-one Device

Modular Design, Easy Expansion
All kinds of our products use modular design, it is very easy to expand capacity by inserting modules. At first, you can place an order with small capacity, after testing, if you want to expand, it is no need to change a device, just need to buy some modules, it is very convenient.

All kinds of signalings on E1 ports
We have been producing E1 products from 2001 year. So we have excellent experience on E1 ports, they support all kinds signaling like ISDN PRI, SS7, R2/CAS, Q.SIG, V5.2, DPNSS, etc. Make connection between different signalings or between PSTN and Ethernet.
