CHAPTER 1
OVERVIEW
This chapter describes the features of the WPIM-T1/DDS. It also briefly
explains the WAN protocols supported by the WPIM-T1/DDS.
Some steps for successful operation of this device are:
• Install the WPIM-T1/DDS in a Wide Area Network host platform.
Referto Chapter 2for directiononinstallationprocedures.Refertothe
appropriate host manual (i.e., the Cabletron Systems CyberSWITCH
CSX400 and CSX400-DC Installation Guide for other installation and
troubleshooting procedures.
• Access Local Management. Refer to the appropriate host platform
Local Management User’s Guide for instructions on setting up and
accessing Local Management.
• Select the service desired, T1 or DDS, using Network Tools.
• Once the desired service has been chosen, refer to the appropriate
chapter in this document for setup information.
Due to the automation of setup features, it is strongly recommended to
use the Graphical User Interface, QuickSET, to fully configure the device.
QuickSET is the desired method for configuring the WPIM-T1/DDS,
after using Local Management to choose T1 or DDS service. Check the
Release Notes for the availability of QuickSET for configuration. Use
Local Management, described in this manual, if QuickSET is not
available.
NOTE
The device in which the WPIM-T1/DDS is to be installed may
be referred to as the host platform in this documentation.

1.1 FIRMWARE REVISION
This manual covers Firmware Revision level 02.01.XX. Later revisions
may be reflected in an updated manual. Please check carefully to verify
the revision level of your device, to ensure that this manual will meet your
needs.
1.2 WPIM-T1/DDS FEATURES
The WPIM-T1/DDS extends the functionality of the Wide Area Network
host platform to provide a full or fractional T1 or a DDS interface for the
host platform (CSX400 or the HSIM-W6) into which the WPIM-T1/DDS
(Figure 1-1) can be installed.
Figure 1-1 WPIM-T1/DDS
In the T1 service mode, the WPIM-T1/DDS provides a T1 interface that
includes a built-in Channel Service Unit/Digital Service Unit (CSU/DSU)
for direct connection to a T1 line.
In the DDS service mode, the WPIM-T1/DDS extends the functionality
of the Wide Area Network module to allow remote connectivity using
Digital Data Service (DDS). It provides a DDS interface that includes a
built-in Channel Service Unit/Digital Service Unit (CSU/DSU) for direct
connection to a DDS line, and supports remote CSU diagnostic loopback
and Non-Latching remote DSU diagnostic loopback.
Important Notice
Depending on the firmware version used in the WPIM-T1/DDS, some
features described in this document may not be supported.Refer to the
Release Notes shipped with the WPIM-T1/DDS to determine which
features are supported.

CHAPTER 2
SETUP AND INSTALLATION
This chapter details set up and installation of the WPIM-T1/DDS into a
host platform.
2.1 INSTALLING THE WPIM-T1/DDS
For additional support related to the WPIM-T1/DDS, refer to the host
platform manual into which the WPIM-T1/DDS is being installed. Locate
the guide by clicking on the Cabletron Systems QuickSET program group
icon after installing the QuickSET CD on your computer, or see Related
Manuals in the Introduction.
2.1.1 Unpacking the WPIM-T1/DDS
1. Carefully remove the WPIM-T1/DDS from the shipping box.
2. Visually inspect the WPIM-T1/DDS. If there are any signs of damage,
contact Cabletron Systems immediately. Refer to Getting Help.
Only qualified personnel should install the WPIM-T1/DDS.This
User’s Guide is intended for the experienced network
equipment installer.
NOTE QuickSET or Local Management must be used to set up the
WPIM-T1/DDS in management before any connections are
made to the WAN. Follow the directions carefully.
NOTE Some WPIMs require version 1.02 or greater of QuickSET to
participate and function correctly in your network. Contact
Cabletron Systems to obtain the latest version of QuickSET if
you do not have it. Refer to Getting Help in the Introduction for
more information.
Both the WPIM-T1/DDS and the host platform in which the
WPIM-T1/DDS is installed are static sensitive devices. Use a
grounding strap and follow all static-safe precautions during
installation. Failure to do so could result in damage to the
WPIM-T1/DDS and the host platform receiving it.

Chapter 2: Setup and Installation
2-2 WPIM-T1/DDS User’s Guide
2.1.2 Pre-Installation
To prepare the host platform for the WPIM-T1/DDS, proceed as follows:
1. Turn off and disconnect the host platform from the power source.
2. Mark all network cables attached to the host platform for ease of
re-installation.
3. Disconnect all network cables attached to the host platform.
4. Refer to detailed instructions contained in the host platform’s user
guide to remove the chassis cover. This procedure must be completed
before installing the WPIM-T1/DDS.
2.1.3 Installing the WPIM-T1/DDS
To install the WPIM-T1/DDS into the device, refer to Figure 2-1 and
complete the following steps:
1. Remove the blank faceplate from the appropriate WAN slot by
removing the three WPIM screws that secure it to the standoffs.
2. Orient the WPIM-T1/DDS as shown in Figure 2-1.
3. Carefully insert the WPIM-T1/DDS connector into the WPIM
connector pins on the device.
4. Press down firmly on the WPIM-T1/DDS until the pins slide all the
way into the connector. Ensure that the WPIM-T1/DDS seats flush on
the standoffs.
5. Secure the WPIM-T1/DDS to the three standoffs with the WPIM
screws.
!
CAUTION
When removing an existing WPIM, make sure to pull the
module straight up to avoid damaging the connector.
