Product Content Description:

1. Summary
Our ZMUX-121 is a "1+1" E1 channel protection device, which is used to distribute the incoming E1 streams to 2 transmission routings through main and stand-by E1 interface, simultaneously, supervision informations of transmission quality is inserted, and the signal from "BETTER" transmission route will be transmitted to subscriber's equipments after the signal quality of transmission is analyzed.
This device can calibrate the delay of two transmissions, the acceptable max delay is 32ms for main and stand-by E1 transmissions. When the switching level is 0, the switching time is ns (bit level), thus, damage (that is caused by routing transmission failure)on subscriber's signal can be eliminated to ensure that subscriber's devices work reliably.
Our ZMUX-121 can automatically or manually switch 1 E1 channel between 1 main and 1 stand-by E1 channel without damage on transmitted data so as to protect 1 important E1 incoming streams from subscriber's device.
2. 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 accurate synchronization between devices;
6) the device features small size, low power power consumption and high reliability based on VLSI solution.
7) the alarms and working status of this device can be collected by connecting PC to the monitoring port on the device.
3. Scope of Applications
This device can supervise real-time signal quality(information of error and alarms)of two routing transmissions and choose one E1 incoming stream based on switching mode to make switching without damage.
