Descriptions

Optical multiplexer ToPGATE-2STM1-2FG

Up to 126 E1 streams transmission via TDMoP that provides transparent connection of any E1 equipment without quality deterioration
Embedded full-featured L2 switch supports all the required standards for modern networks construction: traffic prioritization with 4 priority queues, VLAN
Building of combined networks with different bandwidth and technologies using 100M, 1G and 10G part of networks. Opportunity of bandwidth extension on
Ethernet level or increasing of E1 streams quantity
2 interfaces of 1000Base-X for optic lines connection and support for RSTP (802.1w) for effective and fault-tolerant operation in modern distributed Ethernet networks with complicated ring topology with redundancy, e.g. ring with spurs, tree
Local (through the serial USB port) and remote management and diagnosis
Support for SNMP, Web, Telnet, local management console, port mirroring, opportunity to save and modify text configurations

TopGATE-2STM1-2FG multiplexer is dedicated for demultiplexing of structured and unstructured E1 streams (G.703, G.704) out of STM-1 stream (SDH) and for transmission of this data through packet data network (Ethernet) via TDMoP. Due to the embedded full-featured Gigabit Ethernet L2+ switch and 2 optic-fiber interfaces (up to 80 km link distance for a single fiber), there is an opportunity to built small transport networks without additional equipment.
