GTT Frame-type Multi-service Transmissio

1. Overview

Every board card of GTT frame-type multi-service optical transmission equipment  adopt LSI with proprietary intellectual property rights, using TDM technology, mix the Ethernet, E1 signals and narrowband service, such as voice etc encoded and transmitting through a couple of optical fiber. Realize the mixed transmission of Ethernet service, E1 service, speech path service, 2/4EM, RS232 or RS485 service etc. Extensive apply in telecom operator telephone bar, major client access, project of optical fiber replaced copper wire and electric power substation communication, public security band four network access, army etc.

2. Performance feature

The frame can plug-in 10 optical direction service card, 1 standard SNMP network management board;

Can mixed plug-in GTT 120HK, GTT 240HK, GTT 120H-1000MK、GTT 240H-1000MK、GTT GL120HK、GTT GL240HK、GTT MUX30K；

Every optical direction provides 2-4 line-rate self-adapting Ethernet port, full/half duplex self-adapting;

Every optical direction optical interface transmission rate is 155M or 1.25G;

Every optical direction provides 15 service slots, FXO/FXS, EM2/4, hotline, magnetic, RS232/RS485 arbitrary configuration;

Every optical direction provides 4-8 E1 interface;

Every optical direction provides 30 routes voice maximum, support caller ID function.
