Ethernet over SDH (STM-1) Product Overview Ø Ø Ø Ethernet over SDH (STM-1) Equipment is a modular platform unit with two pluggable 155. 52 Mbps optical / electrical interfaces. Used in a point-to-point, chain or ring application to provide a compact, cost effective and flexible solution to deliver multiple Ethernet channels. Interface card options include the 4 x 100 Base. T Ethernet interface card (1 VCG, 4 Ports 1 Channel), 4 x 100 Base. T Ethernet interface card (4 VCG, 4 Ports 4 Channels) and Gigabit Ethernet interface card options along with Engineering Order Wire is available. The user removable / replaceable STM-1 Optical / Electrical interface option makes it easy to meet various and changing user requirements. STM-1, Ethernet and Gigabit Ethernet over SDH Transmission Equipment provides full capability to cross-connect at VC-12 level between all tributaries. The equipment can be used as Terminal Multiplexer (TM) or an Add-Drop. Multiplexer (ADM) to build a point-to-point, chain or ring SDH transmission network.
