ROIP Wireless Cluster Intercom Gateway VoIP/SIP Gateways

ROIP Wireless Cluster Intercom Gateway

It can achieve the interconnection of wireless radio and PSTN network telephone. It can also support all kinds of radio such as simulation routine, digital routine, simulation cluster, digital cluster, shortwave and so one.

Function description:

Cluster intercom has developed for a long time and most of the users own perfect wireless network coverage. At present, there are many industries and units using this kind of equipment. And the compatibility of the original equipment should be considered in the capacity expansion

The deficiency is a single communication mode, focus on cluster intercom.

Wireless cluster intercom gateway is a kind of powerful voice access equipment and it is convenient to integrate the cluster intercom system and telephone system. The users can easily call the intercom through telephone and also can dial the phone through intercom. System supports the traditional PSTN telephone line and VOIP based SIP phone line. And the deployment and use are very convenient, can be achieved, namely, plug and play.

Cluster intercom gateway has a strong networking ability and sound processing capabilities, using microcomputer chip technology and electronic switch control technology. Each controlling parts are independent and the operation of cutting in and cutting out the signal is sensitive. It can achieve 2 Road, 4 road (1U), 48 Road (3U) and intercom access. Using DB9 plug, 6U equipment configuration RJ45 plug, configuration professional radio control cable.

Cluster intercom gateway deployment simple and flexible, simple connection can be used. Support PSTN, SIP, compatible with multi type hand, radio. Standard 19 inch rack mounting, safe and reliable. 

The equipment support for the general telephone and IP interface (IAD), can access the PBX subscriber line, Telecom Bureau user line, analog user gateway IAD and other equipments.

And can support the IP-PBX, soft switch, SIP server SIP application of the major companies. And can be in the general scheduling command system seamless.

MCC IDM is based on the IP network of the next generation scheduling communication system, from the management, use, deployment, maintenance and other aspects to meet the needs of the user's intelligent command and scheduling communication needs. Due to the short development time, MCC IDM focuses more on the transmission, access, and the interconnection of the special network. The application of the cable network is not as good as the application of cluster system in wireless network communication.

Through the gateway, the MCC IDM multimedia scheduling and wireless cluster are integrated, which can give full play to the advantages of the two systems, the formation of a set of wireless connection, wide coverage, rich communication mode, the use of flexible and convenient management and maintenance of the command and dispatch communication system to meet the needs of users from the traditional communication to upgrade the needs of intelligent communications, and can protect the original investment. 

Implementation of cluster interconnection gateway cluster, including the simulation cluster, TETRA, GOTA and other traditional cluster, cluster intercom system and the new IP network intercom voice gateway device. To achieve the PTT system connection professional and traditional cluster system (iDEN, TETRA, GOTA, analog intercom etc.), between different bands of cluster system, cluster and digital analog trunked system interconnection, no restriction on the number of clusters and regional, cross section of inter network interoperability, flexibility, simple implementation of the project.

Through the intercom gateway can call each other in the country or the world through mobile phone, telephone, and any traditional voice intercom system. Through the cluster intercom voice gateway can make mobile phone intercom system, digital trunked system (TETRA, GOTA), analog trunked system and the conventional radio frequency intercom access to CDMA, GPRS, WIFI easy, business network, LAN, Internet, wireless intercom to achieve long-distance communication together.

The main problem of it is to solve the problem of real time and PTT signal without error, so as to solve the problem of transmission power, antenna sensitivity and transmission distance. Through the IP network, Internet radio signals to complete small power ultra long distance across the region, the typical application of the public security departments have cross city and inter provincial wireless dispatching, large enterprises north and south between segments of wireless communication, a wide range of mine Unified Wireless dispatching. The application of RoIP technology in the near distance can be used to complete the small power cell wireless signal coverage in the local area network, which is a reform of the traditional large power relay station.

6. Principle

The wireless cluster gateway is connected with the wireless system to realize the interconnection between the wired network and the wireless network.

The IP side of the wireless cluster gateway is connected to the IP network through the Ethernet port, as the terminal registration system of the scheduling system.

The wireless side is the terminal of the wireless cluster system, which is connected to the wireless cluster system by the radio relay circuit.

As for wireless networks and SIP networks, the wireless cluster gateway is equivalent to a terminal, which has an independent broadcast channel and an extension number.

The cluster gateway can be used as a terminal to the Server SIP NGN network.

Wireless cluster can be through PTT key or DTMF dial call cluster gateway a terminal telephone number, can also correspond to an intercom group and group meeting.
