JSQ-1000是由桑达公司程控部自行设计开发的容量范围为128-4096个用户端口/中继端口的全数字时分程控交换机,可作为专用网交换设备或本地电话网C5端使用。其主要特点如下: 1.全分散控制方式,以128端口为一子模块,各模块为一独立交换子系统,各子系统CPUU的级别安全相同,最多可由32个模块叠加组成一个具有4096端口的交换机系统。 JSQ-1000 is an all-digital time-division programmable switch whose capacity range is 128-4096 user ports / trunk ports, which is designed and developed by SEDA program control department. It can be used as private network switching equipment or local telephone network C5 terminal. Its main features are as follows: 1 fully decentralized control mode to 128 ports as a sub-module, each module is an independent switching subsystem, the same level of security in each subsystem CPUU, up to 32 modules can be superimposed to form a 4096 port Switch system.
