300 channels telephone over fiber+100M multiplexer

Brief Introduction IDM-300ME voice access equipment provides two shared wire-speed Ethernet interface 100M, at the same time can provide 6 Group series of E1, of which 4 groups of E1 interface which are of 75 European-African, 2 groups of 120 European standard E1 interface, with polarity reversal and caller ID-enabled phones. FXO, FXS, may be filled with 300 lines of users, the device provides service for a total bandwidth of 155M. Transmission can be achieved easily in a cost saving result . IDM-300ME also provides management of disk-controlled CMU, power supply, backup bell flow features, a great service to ensure the reliability of transmission. Features 1. Single optical path direction of 300 telephone user interface capacity. 2. Provides wire-speed Ethernet channel 100M can work in full-duplex/half-duplex. 3. Mutually redundant CMU Medium Control panel, while providing transmission 6 groups through E1 channel group. 4. Owns perfect simple network management functions. 5. With multiple clock mode, can meet a variety of application environments clock requires.
