Supports remote transmission of audio/video, telephone, E1 leased line, and network data, enabling localized telephone self-organizing networks and connectivity to superior networks.
The vehicle-mounted emergency wired transmission integrated service system includes PT-50 VM7U field frame type equipment , analog junction box, digital junction box and remote PT-50 PU portable equipment, which are used for the connection between the command center and the outfield to complete the remote connection of audio and video, telephone, E1 and network, Realize localized program-controlled telephone self-organization network and access to superior switching network through digital trunk or analog trunk.The central office equipment has the command and dispatching functions of video matrix and conference telephone, and the remote equipment can communicate with each other. The command center shall conduct centralized management on the equipment in the outfield, and the optical fiber or field cable can be used for the connection. The equipment adopts the form of portable case, and the interior of the case adopts modular design. Different business cards can be configured according to different use requirements to meet the different usage scale of each business.
Ø Supper Reliability
The center shelf design is ruggedized, anti-knock and dustproof; the master control cards and power supply cards adopt redundant backup; Board support hot swappable;
Ø The remote device is designed as a high-strength plastic case, which is wear-resistant and fall resistant, sealed and rain proof, easy to carry and flexible to use. High temperature resistant, dust-proof and portable equipment;
Ø Various service interface type
FXO、FXS、2/4W E&M、RS232、RS485、V35、G703、ETH、carrier、magnet、audio/video etc;
Ø Various transmission interface
E1、PDH、SDH、IP、HDSL interface etc;
ØIP PBX function
Support SS7, PRI, R2 and V5 digital relay protocols, analog relay protocols, SIP soft switch protocols, DTMF and pulse dialing, conference, recording, dispatch, queuing etc;
Ø Video splicing function
Support 2 * 2, 3 * 3 and 4 * 4 video splicing, support audio and video synchronization;
Ø Powerful NMS
Through NMS network management system, the equipment can be configured with complete operation parameters, which makes the maintenance of the equipment simple and effective;
Ø Advantages of remote equipment design
The shelf is designed as an internal double-layer structure, and the lower layer is the cable placement space. The cable is easy to be placed and taken, and is not easy to be lost or damaged;
The equipment is powered by 220V, with built-in lithium battery with floating charge. When 220V is lost, lithium battery can be used for 2 hours;
Ø The firmware and software of the device can be upgraded remotely.
