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. Function Description Concurrently, our ZMUX-121 can transmit incoming E1 stream from subscriber's device to 2 routing transmissions,automatically choose and send the BETTER E1 signal to subscriber's device after receiving the incoming E1 streams from 2 transmissions. In PCM30 framing format,our ZMUX-121 is suitable for PCM framing channel that complies with ITU-T G.703, G.704, G.823 recommendations.
In PCM unframing format, our ZMUX-121 is suitable for PCM unframing E1 channels, such as IP circuit of multi-link layer protocols,point to point dedicated circuits of CISCO HDLC protocol, frame relay circuit of LAPF protocol, X.25 circuit of LAPB protocol.
The two main functions of our ZMUX-121 are supervisions on performance of transmission channels and safe switching control.
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.
The max delay of two E1 links is up to 32ms, |
