CHAPTER 1 INTRODUCTION Welcome to the Cabletron Systems WPIM-E1 Local Management Guide. This manual explains how to use Local Management to control and manage the Cabletron Systems WPIM-E1. Appendix A of this guide provides connector and pinout information for the WPIM-E1. The WPIM-E1 resides in and provides connectivity/functionality to Cabletron Systems Wide Area Network (WAN) modules such as the BRIM-W6. Before using this manual you must: • Install the WPIM-E1 in a Wide Area Network module.
CHAPTER 1: INTRODUCTION The following list briefly explains each chapter of the WPIM-E1 manual: Chapter 1, Introduction, outlines the contents of this manual, describes WPIM-E1 features, lists specifications, and concludes with a list of related manuals. Chapter 2, Local Management, describes how to use Local Management to setup the WPIM-E1. Appendix A, WAN Interface Cable Specifications, provides Cabletron part numbers and connector information for the interface cables used with the WPIM-E1.

CHAPTER 2 LOCAL MANAGEMENT This Chapter explains how to configure the WPIM-E1 through Local Management. The WAN Physical Configuration screen and the WAN Interface Configuration screen appear as Local Management menu selections after you install the WPIM-E1 into a WAN module such as the BRIM-W6 and then install the BRIM into a MIM or standalone hub. Refer to the MIM or standalone hub User’s Guide for instructions about how to setup and access Local Management.
CHAPTER 2: LOCAL MANAGEMENT 2.1 THE WAN PHYSICAL CONFIGURATION SCREEN To access the WAN Physical Configuration screen from the Feature Selection screen, use the arrow keys to highlight the WAN Configuration option, then press ENTER. The screen shown in Figure 2-1 appears. Local Management Flash Image Version: xx.xx.
THE WAN PHYSICAL CONFIGURATION SCREEN The WAN Physical Configuration screen displays the following information for each WPIM: WPIM 1-4 Displays configuration information for as many as four WPIMs. Each BRIM-W6 supports two WPIMs. Some of Cabletron’s products (e.g., the NBR-620 or the EMM-E6) will support two BRIM-W6 modules providing connectivity for as many as four WPIMs. Only one WPIM per BRIM-W6 can be active. NOTE Type Displays the WPIM type.
CHAPTER 2: LOCAL MANAGEMENT NOTE The service provider determines the settings for the following fields. Consult the service provider for the correct settings. E1 Timeslot View Displays the status of the Timeslot Configuration Table. The selections for this field toggle between Active and New. The Active setting displays current Timeslot Configuration table settings. The default setting is Active. The New setting allows you to change Timeslot Configuration table settings.
THE WAN PHYSICAL CONFIGURATION SCREEN 2.1.3 The WPIM Timeslot Configuration Table The WPIM Timeslot Configuration Table allows the user to configure the way in which the Cabletron WAN module uses the E-1 line. The configuration table consists of 32 Timeslots. Only 31 of the Timeslots are available for use because the first Timeslot is used by the device to transmit framing data. N/A (Not Available) always appears in Timeslot #1.
CHAPTER 2: LOCAL MANAGEMENT Figure 2-3 shows a sample configuration for three sites. Of the 32 Timeslots, Site #1 uses the first Timeslot for transmitting framing data, 23 Timeslots to communicate with Site #2 and the remaining 8 Timeslots to communicate with Site #3. This configuration varies tremendously depending on how the service provider maps out the E-1 Timeslots. Your service provider will tell you which Timeslots are active and where they go in the cloud.
THE WAN INTERFACE CONFIGURATION SCREEN 2.2 THE WAN INTERFACE CONFIGURATION SCREEN This section describes the features of the WAN Interface Configuration screen. Access the screen by using the arrow keys to highlight the WAN Int Config option at the bottom of the Physical Configuration screen, then press ENTER. The WAN Interface Configuration screen shown in Figure 2-4 appears. Local Management Flash Image Version: xx.xx.
CHAPTER 2: LOCAL MANAGEMENT 2.2.1 WAN Interface Configuration Screen Fields This section describe the WAN Interface Configuration screen fields. Interface Number Displays the active Interface Numbers. Use this field to configure the Interface Numbers you assigned to the Timeslots on the WAN Physical Configuration screen. Data Compression Displays the status of Data Compression. This field displays YES or NO. The default setting is NO.
THE WAN INTERFACE CONFIGURATION SCREEN If NO LMI is selected, the following fields are displayed: DLCI Address: This field can be set to values from 0-1023. The values 0-15 and 1008-1022 are reserved DLCI addresses. Circuit State: Toggles between Active, Inactive and Invalid. PT# Displays the application ports (bridge ports) available from the host platform to the WAN. If the active protocol is PPP, Local Management assigns only one application port per interface number (IF#).
