1.2 OVERVIEW
The HSIM-W87 extends the functionality of certain Cabletron Systems
platforms by providing an interface for Wide Area Network (WAN) DS3
services. The HSIM-W87 is a High Speed Interface Module (HSIM) used
to provide WAN services using the SmartSwitch series of products as a
platform. The HSIM-W87 has a physical DS3 interface, providing up to
28 separate logical DS1 connections. The 28 T1 circuits are all capable of
acting either as a single 45 Mbps full duplex data circuit or as individual
T1 circuits within a Layer 2 Inverse Multiplexing (IMUX) group.
The typical configuration is a head-end WAN aggregation point for up to
28 T1s into a single WAN physical interface. The HSIM-W87 is able to
uplink any combination of single T1s or multiple T1 IMUX groups to the
backbone.
NOTE
The term “host platform” is used to describe the interface
module, or standalone device, into which the HSIM-W87 can
be installed.
