  •      Centralized management 4U chassis telephone over fiber

     The integrated rack/frame is an economical standard 19-inch rack that can meet users' centralized use and centralized management. The system has over-temperature, over-voltage and over-current protection devices. The frame can provide dual power supplies with 1+1 backup power supply and centralized SNMP network management.
    Functional Features
    ◆ Standard 19-inch chassis, which can be installed in the server room rack for unified management and maintenance.
    ◆ Modular power supply design, easy maintenance and better shielding.
    ◆ Prevents the electromagnetic signals generated by the power supply from interfering with the normal operation of the module set.
    ◆ The rack can insert multiple telephone optical transceiver boards at the same time, and can mix a variety of boards; supports hot-swapping function.
    ◆ Full compliance with telecom-grade operation requirements, with an average trouble-free working time of more than 100,000 hours.
    ◆ 4U frame is 17 slots plus pluggable dual power supply, can insert 17 pieces of 4U E1 PCM cards and can be SNMP network management cards supported by 1-16 way telephone E1 PCM card; 4 way telephone + 1FE + 2 way serial card; 8 way telephone + 4 way RS232 data card, etc.;
    ◆ 6U frame is 13 slots plus pluggable dual power supply, 13 boards can be inserted with 6U E1 PCM card and can be supported by SNMP network management, such as 30-way telephone E1 PCM multiplexer card; 29-way telephone + 1*FE + 1*serial E1 PCM card;
