Configuring Avaya MM342 USP WAN media module

Last Updated : Mar 26, 2020 |

Procedure

  1. Use the interface serial command to enter the context of the interface.

    Specify the slot number of the media module, the port 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 port, the Branch Gateway automatically assigns IP interface number 0. For each additional Serial interface that you define on the port, use a different IP interface number.

    For example:

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

    • interface serial 4/1.2. Enter a serial interface on the media module in slot number 4, on port number 1, with IP interface number 2.

    Gxxx-001(super)# interface serial 3/1

    The prompt changes to:

    Gxxx-001(super-if:serial 3/1)#
  2. Use the following commands to change the idle characters, transmitter delay, encoding type, bandwidth parameters, line monitoring, and from their default settings:

    • idle character flags|marks. Set the bit pattern used to indicate an idle line. Use the no form of this command to restore the default value (flags).

    • transmitter-delay number. Set the minimum number of flags to be sent between successive packets. Use the no form of the command to restore the transmitter-delay value to the default (0).

      Note:

      The transmitter-delay command is usually used when the DCE equipment that is connected directly to the Gateway, or the router on the WAN have a receive buffer that is not large enough to hold the traffic sent by the Gateway. In this case, configure transmitter-delay on the DCE equipment or the remote router in order to preserve the high performance that you had when transmitter-delay was configured to 0 on the Gateway.

    • nrzi-encoding. Enable the non-return-to-zero inverted (NRZI) line coding format on the specified interface. Use the no form of the command to disable NRZI encoding.

    • bandwidth kbps. Set the bandwidth parameter manually for the interface. Use the no form of this command to restore the bandwidth parameter to its default value (2,048). The manually specified bandwidth value overrides the dynamically calculated bandwidth during route cost calculations.

      Note:

      If you are using the USP port as a clock source, configure the port’s bandwidth to match the DCE clock rate.

    • ignore dcd. Specify how the system monitors the line to determine if it is up or down. Specify ignore dcd to ignore DCD signals, and instead use DSR/CTS signals to determine the line’s status. Use the no form of the command to specify that DCD signals are used to determine line status.

    • invert txclock. Invert the transmit clock signal from the data communications equipment (DCE). Use the no form of the command to restore the signal to not inverted.

  3. Configure the interface encapsulation.
  4. Enter exit to return to general context.

    The prompt returns to:

    Gxxx-001(super)#
  5. Repeat Step 1 to configure additional Serial interfaces on the USP port.
  6. Test the WAN configuration.
  7. Enter copy running-config startup-config to save the configuration.
