Chapter 1: Overview

1.1WPIM-RT1 FEATURES

The WPIM-RT1 extends the functionality of the Wide Area Network host platform to provide a full or fractional T1 interface for the CSX400, HSIM-W6, or the HSIM-SSA710. The WPIM-RT1 provides a T1 interface that includes a built-in Channel Service Unit/Digital Service Unit (CSU/DSU) for direct connection to a T1 line.

1.2WAN PROTOCOLS

The WAN protocols that are supported are determined by the host platform in which the WPIM-RT1 is installed. Refer to the host platform manual to find the protocols supported.

1.3ISDN

ISDN provides inexpensive switched digital access to remote sites. The ISDN BRI standard provides for two high speed 64 Kbps bearer (B) channels used for voice or data connections and one 16 Kbps signaling data (D) channel used for call setup, signaling and other information. ISDN allows all types of information to be transmitted including voice, data, fax and video. Multiple devices can be linked to a single ISDN connection, each having their own telephone number. Two or more channels can be combined into a single larger transmission pipe offering variable transmission speeds.

1.4MIB SUPPORT

Refer to the Release Notes included with the host platform for a list of all MIBs supported by the WPIM-RT1. For information about how to extract and compile individual MIBs, contact Cabletron Systems (see Getting Help).
