DUAL GIGABIT ETHERNET CONTROLLER

Edge Routers and Core Routers within a POP are provided via Gigabit Ethernet.

Co-located server clusters are also connected via Gigabit Ethernet to POP

routers. Similarly, Gigabit Ethernet is becoming the choice for connection

between Enterprise Routers and Multi-Service switches. Transport equipment is

looking to provide Ethernet directly over SONET/SDH for wide area transparent

bridging.

In a typical application the S/UNI-2xGE performs data recovery on the Gigabit

Ethernet stream, MAC level frame checks and sends the frame to an upper layer

device (such as an IP processor) for forwarding via the POS-PHY level 3

interface. The S/UNI-2xGE maintains extensive statistics for SNMP and RMON

applications. On egress, frames are formatted into physical frames with the

proper inter-frame gap, preamble and start of frame delimiter. The physical

packet is then serialized for transmission over an external electrical optical

module. The initial configuration and ongoing control and monitoring of the

S/UNI-2xGE are provided via a generic microprocessor interface. The following

diagram shows a typical multi-service card application for the PM3386 S/UNI-

2xGE with similar cards for OC48 and Quad OC-12 ports.
