Chapter 1: Overview
1-2 WPIM-RT1 User’s Guide
1.1 WPIM-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.
1.2 WAN 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.
1.3 ISDN
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.
1.4 MIB 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
