TokenSpeed Module Ports and Connectivity

TokenSpeed module ports have the following features:

•Operation at 4 or 16 megabits per second (Mb/s), with automatic sensing of the data rate of an inserting station

•Onboard connectors

—RJ-45 connector for UTP/STP connection to each token ring port

—One serial port with a Mini DIN 8 connector on the TokenSpeed/MCP module

•Transparent, source route, and source route transparent bridging with IEEE 802.1d or IBM Spanning Tree support

•Virtual ring partitioning for any combination of ports in a single switch, each virtual ring appearing as a single ring in a source-routing network

•Per-port features

—LEDs to indicate operational status of each port

—Automatic adaptation to speed of inserting station: 4 or 16 Mb/s

—Automatic port deactivation for errors or administrative control

—Wire-speed port-to-port switching for local trafﬁc without using any ATM backplane bandwidth
