Product Description

ZMUX-35 is a DXC digital cross-connect device. It can access the non-blocking cross-connect function of any 64K time slot between 16 E1s by accessing 1~16 E1 signals. It has the ability to process the associated channel signaling (CAS). The synchronous clock can be extracted through the line or generated synchronously inside the device.

    The ZMUX-35 is modular in design and provides four 4×E1 module slots. Optional: 4×E1, 8×E1, 12×E1, and 16×E1.

    ZMUX-35 has two DB37 connectors. Each DB37 connector can access 1~8 E1 signals, and provide 16 E1 interfaces to realize 16-channel E1 full-slot cross-connect function.

 

Features

    Less space: 19-inch 1U chassis.

    Flexible configuration: modular design, flexible configuration of system capacity, optional 4 × E1, 8 × E1, 12 × E1, 16 × E1 four specifications.

    E1 impedance: optional 75 ohm balance or 120 ohm unbalance.

    E1 frame format: optional PCM30 or PCM31 format.

    Channel-dependent signaling: With channel-to-channel signaling (CAS) cross-processing.

    One-way broadcast: Optional one-way broadcast (point-to-multipoint transmission).

    Network management function: Optional network management function, which can monitor the configuration information of the entire network, E1 link status, E1 protection status, and user interface status.

    E1 monitoring: It can monitor fault alarms such as LOS, AIS and LOF of E1 line.

    Power protection: central office equipment, remote equipment, each equipment can provide two completely independent working power boards, primary and backup protection;

    Power monitoring: Support real-time monitoring of the working status of the central unit and remote unit's built-in power board, and also support the real-time monitoring function of the external Emerson switching power supply.
