CHAPTER 1 INTRODUCTION Welcome to the Cabletron Systems WPIM-T1 Local Management Guide. This manual explains how to use Local Management to control and manage the Cabletron Systems WPIM-T1. Appendix A of this guide provides connector and pinout information for the WPIM-T1. The WPIM-T1 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-T1 in a Wide Area Network module.
CHAPTER 1: INTRODUCTION The following list briefly explains each chapter of the WPIM-T1 manual. Chapter 1, Introduction, outlines the contents of this manual, describes WPIM-T1 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-T1. Appendix A, WAN Interface Cable Specifications, provides Cabletron part numbers and connector information for WPIM-T1 interface cables.
WPIM-T1 FEATURES 1.3 WPIM-T1 FEATURES The WPIM-T1 extends the functionality of your Wide Area Network module to allow remote connectivity using WAN services such as T-1, or Fractional T-1. The WPIM-T1 provides a T-1 interface that includes a built-in Channel Service Unit/Digital Service Unit (CSU/DSU) for direct connection to a T-1 line. This WPIM supports both Full T-1 or Fractional T-1 using 56 or 64 Kbps timeslots.
CHAPTER 1: INTRODUCTION 1.5 WPIM-T1 SPECIFICATIONS This section describes the environmental specifications and safety and approval requirements for the WPIM-T1. Cabletron Systems reserves the right to change these specifications at any time without notice.
CHAPTER 2 LOCAL MANAGEMENT This Chapter explains how to configure the WPIM-T1 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-T1 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 technical documentation for instructions about how to set up 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 (i.e., AT&T, Sprint, MCI, NYNEX, etc.) determines the settings for the following fields. Consult the service provider for the correct settings. T1 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 WAN PHYSICAL CONFIGURATION SCREEN T1 Network Loopback Network Loopback is a testing procedure that segments the line and allows the user to isolate faults. The selections for this field toggle between None and Line-Loop. In Line-Loop all 24 channels are looped back to the T-1 line.The WPIM-T1 must be in Loop-Timing mode to use this option. The default setting is None. 2.1.
CHAPTER 2: LOCAL MANAGEMENT Figure 2-3 shows a sample configuration for three sites. Of the 24 Timeslots, Site #1 uses 16 to communicate with Site #2 and the remaining 8 to communicate with Site #3. This configuration varies tremendously depending on how the service provider maps out the T-1 Timeslots. Your service provider will tell you which Timeslots are active.
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 Data Compression Displays the status of Data Compression. This field displays YES or NO. The default setting is NO. Max Xmit Unit User-configured field that displays the maximum packet size that can be transmitted on the selected interface. The default settings for this field are 8191 for PPP and 4095 for Frame Relay. Line Coding Displays the Line Coding for timeslots associated with this interface. This field displays JBZS, INV-HDLC, or None.
THE WAN INTERFACE CONFIGURATION SCREEN 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#). If the active protocol is Frame Relay, Local Management assigns the available WAN bridge ports from the host platform, one per DLCI. You can assign WAN application ports to the 24 interfaces for the PPP configuration that suits your needs.
