 Overview:

      GTT-PCM series Telephone Optical Multiplexer adopt economic integrated service optical access system developed by autonomous LSI of Beijing GTT, adopt rich optical fiber resource, and extend PSTN, distribute numbers to distant users, provide user loop etc. This system contains GTT-PCM30, GTT-PCM90, GTT-PCM120 etc, can select flexible configuration according to number of uses. It is extensive applied in “optical fiber replaced copper wire” project of Telecom, Netcom, Unicom, major client access, telephone bar, and electric power substation communication, replaced the mode of traditional optical terminal plus PCM, greatly saving investment.

Feature:

       Directly transmit 1-240 route service interfaces (service interface contains: common telephone interface, hotline interface, magnetic phone interface, Ethernet interface, RS232/422/485 interface, 2/4 wire audio interface, 2/4 wire EM interface) on optical fiber;

       Provide 1 route optical interface; rate is 155Mbit/s;

       Support single fiber duplex analog, saving fiber resource;

       Modularized design; plug-in plate type structure; interface combination more flexible;

       Speech interface has caller ID detection function and reversal function;

       Transmission distance without relay more than 120KM;
