The T1 port also meets FCC Part 68. 1.6 RELATED MANUALS Use the following manuals to supplement the procedures, and other technical data provided in this manual. This manual references procedures in these manuals, where appropriate, but does not repeat them.
CHAPTER 2 INSTALLATION This chapter describes how to install the BRIM-WT1 to the MicroMMAC. To install the BRIM-WT1, you need to remove MicroMMAC’s chassis cover. Refer to the MicroMMAC User’s Guide for instructions to remove the chassis cover. You also need a Phillips-head screwdriver to install the BRIM-WT1. 2.1 UNPACKING THE BRIM-WT1 Unpack the BRIM-WT1 as follows: 1. Remove the shipping material covering the BRIM-WT1 in the shipping box. 2. Carefully remove the BRIM-WT1 from the shipping box. 3.
CHAPTER 2: INSTALLATION 2.2 INSTALLING THE BRIM-WT1 Caution: The BRIM-WT1 and the boards associated with the MicroMMAC are sensitive to static discharges. Be sure to use an antistatic wrist strap and observe all static precautions during this procedure. Failure to do so could result in damage to the BRIM-WT1 or the MicroMMAC. To Install the BRIM-WT1 into the MicroMMAC: 1. Remove the screws from the BRIM slot faceplate at the rear panel of the MicroMMAC as shown in Figure 2-1. 2.
INSTALLING THE BRIM-WT1 3. Position the BRIM-WT1 in the MicroMMAC as shown in Figure 2-2. Ensure that the connector on the BRIM-WT1 sits flush on the MicroMMAC connector.

CHAPTER 3 LOCAL MANAGEMENT This Chapter explains how to use the BRIM-WT1 local management screens. The WAN Physical Configuration screen and the WAN Interface Configuration screen appear as local management menu selections after you successfully install the BRIM-WT1 into the MicroMMAC. Refer to the MicroMMAC User’s Guide for instructions on how to setup and access local management. 3.
CHAPTER 3: LOCAL MANAGEMENT The following sections describe WAN Physical Configuration screen fields and instructions for setting them. Active WAN Port Displays the active WAN port. In future MicroMMAC releases, this field will be used for port redundancy. Default WAN Port Displays the default WAN port used for the WAN connection. The selections are SYNC or T1. Sync Port Type Displays the Sync Port electrical interface type. The selections toggle between V.35, RS422, RS232, and NONE.
The WAN PHYSICAL CONFIGURATION SCREEN Force DSR True Displays the source of the Data Set Ready (DSR) signal. You can toggle the selections between YES and NO. The YES (On) setting indicates that the DSR is internally “Forced True” (from the BRIM-WT1). The NO (Off) setting indicates that the CTS signal is received from an external DCE. The default setting is NO. T1 Timeslot View Displays the status of the T1 Timeslot Configuration Table. The selections for this field toggle between Active and New.
CHAPTER 3: LOCAL MANAGEMENT Setting WAN Physical Configuration Screen Fields To set a WAN Physical Configuration screen field: 1. Use the arrow keys to highlight the WAN Physical Configuration screen field you want to change. 2. Press the Return key to toggle the selections. 3. When the desired selection appears, use the arrow keys to highlight the SAVE command. 4. Press the Return key or press F6. The message “Save Done!” appears and the changes are saved to memory.
The WAN PHYSICAL CONFIGURATION SCREEN Figure 3-3 shows a sample configuration for three MicroMMACs. Of the 24 Timeslots, MicroMMAC#1 uses 16 to communicate with MicroMMAC#2 and the remaining 8 to communicate with MicroMMAC#3. This configuration can vary tremendously, depending on how the Telco carrier maps out the T1 Timeslots. Your Telco carrier will tell you which Timeslots are active.
CHAPTER 3: LOCAL MANAGEMENT 3. The T1 Timeslot View field displays New and the cursor automatically moves into the Timeslot Configuration table. 4. Use the arrow keys to move to the desired Timeslots in the Timeslot Configuration table. 5. Type the desired Interface Number (03 to 26; or zero (00) for unused Timeslots). Note: The MicroMMAC automatically assigns Interface 01 for Ethernet, and Interface 02 for the SYNC port. 6. Press the Return key. 7. Repeat steps 4 -6 to complete the configuration. 8.
THE WAN INTERFACE CONFIGURATION SCREEN 3.2 THE WAN INTERFACE CONFIGURATION SCREEN This section describes the features of the WAN Interface Configuration screen. To access the WAN Interface Configuration screen from the Features Selection screen, use the arrow keys to highlight the WAN Int. Config. option, then press the Return key. The WAN Interface Configuration screen shown in Figure 3-4 appears. MicroMMAC/WT1 LOCAL MANAGEMENT Cabletron MMW Revision xx.xx.
CHAPTER 3: LOCAL MANAGEMENT Max Xmit Unit Displays the maximum packet size that can be transmitted on the selected Interface. The default setting for this field is 1518. This is the maximum packet size. Line Coding Displays the T1 Line Coding. This field displays INV-HDLC, JBZS, B8ZS, or NOT USED. The default setting for this field is NOT USED. Active Protocol Displays the active Link Layer protocol. This field displays PPP (Point to Point), FR (Frame Relay), or None.
THE WAN INTERFACE CONFIGURATION SCREEN STATE Displays the status of the bridge port. This field is specific to the Frame Relay protocol. If the active protocol is Frame Relay, this field displays the status as ACTIVE or INACTIVE. If the active protocol is PPP, this field appears empty. Configuring Interfaces The BRIM-WT1 Local Management Automatically assigns bridge ports to interfaces. There are 31 Bridge Ports available. To configure an Interface Number: 1.
CHAPTER 3: LOCAL MANAGEMENT Setting the Data Compression Field To set the Data Compression field: 1. Use the arrow keys to highlight the Data Compression field. 2. Press the Return key to toggle between Yes and NO. Select the desired setting. 3. Use the arrow keys to highlight the SAVE command. 4. Press the Return key or press F6. The message “Save Done!” appears. The BRIM-WT1 Local Management automatically assigns an Active Port Number to the Interface number and the changes are saved to memory.
THE WAN INTERFACE CONFIGURATION SCREEN Setting the Line Coding Field Before setting the Line Coding field, you must first set the T1 Line Coding field in the WAN Physical Configuration screen to OTHER. To set the Line Coding field: 1. Use the arrow keys to highlight the Line Coding field. 2. Enter the desired setting. 3. Use the arrow keys to highlight the SAVE command. 4. Press the Return key or press F6. The message “Save Done!” appears.

CHAPTER 4 USING THE LANVIEW LEDS This chapter describes how to use the LANVIEW LEDs to monitor BRIM status and diagnose BRIM problems. SYNC T1/FT1 BRIM-WT LOS YEL STB DSR LNK TST RED SYN CTS TST Figure 4-1. 4.1 BRIM-WT1 LEDS The following LEDs indicate the status of the BRIM-WT1. STB (Standby) • • • On - All WAN bridge ports are in the non-forwarding state. Possible causes of this condition are: redundancy detected by Spanning Tree, data link layer down, physical layer down, or port disabled.
CHAPTER 4: USING THE LANVIEW LEDS 4.2 T1/FT1 PORT LEDS The following LEDs indicate the status of the T1/FT1 port. LOS (Loss of Signal) • • On - Indicates a loss of link at the T1/FT1 port. This condition occurs when the T1/FT1 port receives 192 consecutive 0’s, this should not happen under normal conditions. Check the T1 port cable. Off - Signal OK. TST (Test) • • On - Indicates that the T1/FT1 port is in the test mode. Off - Indicates that the T1/FT1 port is in the non-test mode.
SYNC PORT LEDS 4.3 SYNC PORT LEDS The following LEDs indicate the status of the SYNC port. DSR (Data Set Ready) • • On - Indicates that the DCE is ready to operate, or that the Force DSR True field (refer to the WAN Physical Configuration screen) is set to YES (On). Off - A valid DSR is not being received from the DCE. Check the cabling or check if the DCE is powered on.
