1U PCM cross multiplexer of 9 optional E1 protection modes

1. Outline
Developed by our R&D team, ZMUX-36 PCM Cross Multiplexer is a flexible modular device whose core technology and intellectual rights are possessed by Guangzhou Yinxun.

The device features high density ports, rugged design, easy operations and much reliable transmission of data.

Equipped with max 4 NX64K Ethernet ports and max 32 subscriber's interfaces for public applications, it can multiplex and crossly distribute channels of voices, data or images or combinations to max 4 E1 interfaces by installing varied subscriber's interfaces. In doing so, some important transmissions of applications can continue working even if one E1 connection cuts off.

2. Functional features
1)Provide max 4 optional basic group interfaces which conforms to the recommendation of ITU-T G.703;
2)With E1 switching and add/drop capability;
3)Optional E1 protection modes that can be provided by our ZMUX-36 can be set by our auxiliary NMS;
4)optional line impedance: 120Ω or 75Ω;
5)extended capacity such as digital signals and signaling processing;
6)Provide max 4 optional N*64K Ethernet and 32 optional subscriber interfaces suitable for varied inputs of different services;
7)The voice interface supports caller ID display;
8)CCB payphone application with polarity reversal;
