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.
