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.
