GTT-120H Apply in Public Security System

Time:2012-04-26   Views:1437 Times    Author:GTT

    

      Presently public security system internal network, especially four-band network, still realized by traditional hiring 2M channel mode mostly, low network bandwidth and transmission capacity. By the developing of IT application and the spread of multimedia integrated service, traditional network formation mode can not satisfy the ever-growing service demand of public security network.

      Traditional mode is put voice (mainly telephone, the interface is E1), data (the interface is 10/100M Ethernet interface), video (mainly monitoring and conference television) signal on two or more communications network. This is not only against comprehensive utilization of resource, but also against centralized management of communication system.

      Therefore should build an integrated service communication platform (contains backbone network and access network), can supply high-quality video, high-speed Ethernet signal, E1 interface in the meantime, increase network utilization maximum.

      According to the analysis of the demand above, Beijing GTT bring a solution based on GTT-120H multi-service integrated transmission platform to city public security protection monitoring network.

      GTT-120H is the optical network platform which is high capacity, multi-service, high expansibility, and has comprehensive managerial capacity, and is special designed for private network user.

It includes service access, optical transmission and service management.

Support configuration by demand for user, it can realize do as wishes.
