HSIM-W87 Configuration
Configuring the T3 interface; configuring T1 connections; setting priority IP Addresses
The HSIM-W87 is a High Speed Interface Module that provides Wide Area
Network (WAN) services. The HSIM has a DS3 interface (T3), providing up to 28
separate DS1 connections (T1). The HSIM-W87 design provides WAN
connectivity to any SmartSwitch that supports HSIM connections.
The HSIM-W87 operates in a switching/bridging mode. With minimal user
conÞguration, the HSIM-W87 forwards data packets received by the host out the
logical DS1 interfaces (the T1 lines). It will also forward packets received on the
DS1 interfaces to or through the host. Up to 16 IP addresses can be conÞgured for
priority transmission across the HSIM-W87.
The HSIM-W87 is conÞgured using three windows: the T3 ConÞguration
window, the T1 ConÞguration window, and the IP Priority ConÞguration
window. These windows are explained in the following sections.
The T3 Configuration Window
You can set certain variables for the DS3 interface using the T3 ConÞg window. To
access the T3 ConÞg window:
1. Click on the T3 port to access the Port menu. (To determine which port is a
T3, select I/F Type from the Port Status menu. The T3 port will be labeled
“DS-3”.)
2. Select HSIM W87 Config (T3). The T3 Config window, Figure 8-1 , will appear.
