Product List GD10


Product Summary:

TEKWAY-155SB is the STM-1 level Synchronous Digital Hierarchy (SDH) system, and fully complied with ITU-T standard. It has two 155.52Mb/s optical interfaces, and supports 63 E1 multiplexing and transmitting. TEKWAY-155SB also has Network Elements Timing Function (NETF) recommended by the ITU-T G.813 standard. It has the capability of 63 x 63 VC-12 Non Blocking Cross Connection and 1+1 channel protection.

It can be used as a Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.

TEKWAY-155SB Network Element Management System is based on the unified network management platform EasySDHTM, which is designed in accordance with related recommendations of ITU-T to realize network resources, equipment configuration, alarm, performance and security management. The softwar can also support unified management on Multiple Optical-Route Non-Interconnected subnet and remote network monitoring by Internet.

Product Summary:

TEKWAY-155C is a STM-1 optical transmission system, whose technical performances fully comply with ITU-T and ETSI standards. The system provides up to 6 155Mb/s aggregate optical interfaces, complete synchronous timing features and a powerful non-blocking cross connection matrix. It can be used for building point-to-point, chain, star or ring networks, with SNCP features, serving departments of Telecom, Traffic or Energy industry, etc. Applications of TEKWAY-155C are:

* Cross MUX, becoming the transmission network hinge, capable of providing up to 6 155Mb/s optical ports, 210 E1 add/drop multiplexing, both high-order and low-order signals can be non-blocking cross-connected;

* TM, becoming transmission module of a large exchanger, multiplexing 231 E1, and providing 1+1 channel protection to each E1;

* Optical Ethernet bridge, becoming centralized access equipment of WAN, realizing remote connection of 88 links of 10/100M Ethernet through E1.


◆ 6-optical-port, STM-1 MADM or TM multiplexer;

◆ Support up to 231 E1-circuit add/drop;

◆ Provide Ethernet access of channelized E1 and DS3 shatekway ring;

◆ Support cross connection of all VC12 and VC3;

◆ Support SETS, it is possible to tracing the line port or external synchronization input, provide external synchronization output, and automatically handle timing source rearrangement according to the failure message or SSM;

◆ Support Path Protection and SNCP, the self-healing time is very short.
