Configuring Avaya MM340 E1/T1 WAN media module

Last Updated : Mar 26, 2020 |

About this task

Use this procedure to configure Avaya MM340 E1/T1 WAN media module.

Procedure

  1. Optionally, use the show controllers command to display the current settings.
  2. Enter show ds-mode to check whether the Branch Gateway is configured for E1 or T1 operation.
  3. Use the ds-mode command to set the mode of the Branch Gateway to E1 or T1.

    Changing the line type requires resetting the module. The default value is T1.

  4. Use the controller {e1 | t1} module_number/port_number command to enter Controller context for the port to be configured.

    The prompt changes to:(super-if:Serial s/p)#, where s is the slot number of the media module, and p is the port number.

  5. Use the following commands to change the clock source, frame type, linecode, or cable length parameters from the default settings:

    • For T1 mode:

      • clock source line|internal (default is line)

      • framing sf|esf (default is sf)

      • linecode ami|b8zs (default is ami)

      • cablelength long|short (default is long, gain26, 0db)

        Note:

        Use the cablelength command to configure the cable’s transmit and receive levels. If the cable is longer than 655 feet, use the command cablelength long gain26|gain36 -15db|-22.5db|-7.5db|0db (default is gain26, 0db). If the cable is 655 feet or less, use the command cablelength short 133ft|266ft|399ft|533ft|655ft (default is 133ft). When using the cablelength short form of the command, the transmit attenuation is configured using the loop length.

      • fdl ansi|att|both (default is both)

      Note:

      The fdl command defines the type of Facility Data Link loopback that the remote line is requested to enter. This command can only be used when ESF framing is defined.

    • For E1 mode:

      • clock source line|internal (default is line)

      • framing crc4|no-crc4|unframed (default is crc4)

      • linecode ami|hdb3 (default is hdb3)

  6. Use the channel-group command to specify the channel group and time slots to be mapped, as well as the DS0 speed.

    Example:

    • For T1 mode: channel-group 1 timeslots 1,3-5,7 speed 64 configures time slots numbered 1, 3-5, and 7 to be mapped in channel-group number 1, and sets the DS0 speed to 64 kbps. The default DS0 speed for T1 mode is 56

    • For E1 mode: channel-group 1 timeslots 1,3-5,7 speed 64 configures time slots numbered 1, 3-5, and 7 to be mapped in channel-group number 1, and sets the DS0 speed to 64 kbps. The default DS0 speed for E1 mode is 64.

  7. Enter exit to return to general context.

    The prompt returns to:

    Gxxx-001(super)#
  8. Use the interface serial command to enter the Serial interface context.

    Specify the slot number of the media module, the port number, the channel group number, and optionally, the IP interface number.

    If you do not specify an IP interface number for the first Serial interface that you define on a channel group, the Branch Gateway automatically assigns IP interface number 0. For each additional Serial interface that you define on the channel group, use a different IP interface number.

    For example:

    • interface serial 3/1:1. Enter a serial interface on the media module in slot number 3, on port number 1, with channel group number 1.

    • interface serial 4/1:2.3. Enter a serial interface on the media module in slot number 4, on port number 1, with channel group number 2, and with IP interface number 3.

    Note:

    If you use the framing unframed command in Step 5 for an E1 port, a channel group is automatically created on the entire E1 bandwidth. The channel group has the number 0. In Step 8, enter interface serial s/p:0, where s is the slot number and p is the port number.

    Note:

    After the Serial interface is created, its default encapsulation is PPP.

  9. Configure the interface encapsulation.

    By default, the Serial interface uses PPP encapsulation.

  10. Use the ip address command to configure the IP address and subnet mask of the interface.
  11. Enter exit to return to general context.

    The prompt returns to:

    Gxxx-001(super)#
  12. If needed, repeat Step 8 through Step 10 to configure additional IP interfaces on the same channel group.
  13. If needed, repeat Step 6 through Step 10 to configure additional channel groups on the same E1 or T1 port.
  14. Test the WAN configuration.

    See WAN configuration and testing connectivity.

  15. Enter copy running-config startup-config to save the configuration.
