6U Centralized Modular PCM multiplex equipment

1. Summary
Featuring in flexible, powerful applications, easy maintenance and upgrade,ZMUX-3300 is a centralized PCM multiplexer with E1 or optical link based on VLSI solution. It supports max 14 tributary boards. Its max capacity is supporting 14 directions of E1 or optical connections. Each tributary board may have 1~30 subscriber interfaces cards for which various types of interface modules can be chosen.

This device is specially designed to make telephone interface monitoring and testing applicable, so users can check the real-time communication quality information of telephone interface. Our auxilary network management console V3.0 can monitor real-time status of the whole telecommunications network, providing perfect functions of telephone line testing and remote access monitoring.
