1. Summary
Our ZMUX-124 is a "1+1" E1 channel protection device, which can switch 2 transmission routings without damage on transmitted data when used in pairs. The comprehensive network management console installed for this device can supervise the signal quality of all channels and their switching status when operation. The transmission routing can be switched to stand-by E1 interface for emergency protection by remote control through network management console or switchgear on local device panel when the main E1 interfaces failure occurs in exchanges.
Our ZMUX-124 can switch 4 E1 channels between 4 main and 4 stand-by E1 channels without damage so as to protect four important E1 incoming streams from subscriber's device.

3. System Characteristics
1) Integration of monitoring transmission quality and automatic switching without damge;
2) When LOS, LOF, AIS alarms occurs on local inputs, AIS will be seen on the remote output;
3) Three switching levels available in PCM framing mode: 10E-4/10E-6/single bit error code;
4) Three switching levels available in PCM unframing mode: packet loss rate of 2%/, 1%, 0.5%;
5) High precision digital PLL technology is adopted to ensure accurat |
