GTT MSAP 2000 Integrated-service Optical
1. Overview
GTT MSAP 2000 integrated service optical transmission platform adopt SDH/MDTP technique kernel design, it is the product of MSTP on access level essentially, but compare with traditional MSTP equipment, MSAP equipment can not only access standard MSTP terminal equipment, but also can access low-cost PDH optical terminal, network optical terminal, protocol converter, optical transceiver and FX optical modem etc terminal equipment.
GTT MSAP 2000 integrated service optical transmission platform has 4 or 8 STM-1/STM-4 uplink optical interfaces, possess totally synchronous timing function, powerful nonblocking cross connection matrix, can use to build point-to-point, chain, star and ring transmission network, SNC/P function, and serve for telecom, traffic, energy, public security, troop etc.
GTT MSAP 2000 integrated service optical transmission platform use STM-1/STM-4 etc optical interface to replace the E1 electric interface of numerous traditional SDH/PDH equipment and Ethernet electric interface of optical transceiver and protocol converter etc, solve the problems of more fault points, high maintenance cost, can not unified network management by excessive of E1 cable or five-type cable, through the conversion of E1, V35, Ethernet etc service to VC12 and unified dispatch, create the condition for flexible service configuration and improve the efficiency of open service. Owing to realize the super-integration of equipment and ports, reduce the machine room space cost of local end PDH, converter, optical transceiver etc equipment, and support unified network management platform at the meantime.
GTT MSAP 2000 integrated service optical transmission platform consists of local equipment, remote equipment and element management system.
