Configuring H.248 Base Root Properties

You can configure default, minimum, and maximum values for properties defined in the H.248 base root package. The virtual BGF uses the default values unless the gateway controller overrides them with an H.248 command. You can configure maximum and minimum values to limit the range of values accepted from the gateway controller. In general, we recommend you use the values that are configured on the router by default.

The base root package is defined in annex E.2 of the Gateway control protocol v3, ITU-T Recommendation H.248.1, September 2005. The properties in this package mostly affect the timers used when the virtual BGF and gateway controller send and receive provisional responses to H.248 commands.

To configure H.248 base root properties:

  1. Access the configuration of the H.248 base root properties.
    [edit services pgcp]user@host# edit gateway bgf-1 h248-properties base-root
  2. Set the default value for the number of milliseconds for the gateway controller to wait for a response to transactions from the virtual BGF.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set normal-mg-execution-time default 600
  3. Set the minimum value for the number of milliseconds for the gateway controller to wait for a response to transactions from the virtual BGF.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set normal-mg-execution-time minimum 500
  4. Set the maximum value for the number of milliseconds for the gateway controller to wait for a response to transactions from the virtual BGF.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set normal-mg-execution-time maximum 1000
  5. Set the default value for the number of milliseconds for the gateway controller to wait for a pending response from the virtual BGF if a transaction cannot be completed.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mg-provisional-response-timer-value default 1000
  6. Set the minimum value for the number of milliseconds for the gateway controller to wait for a pending response from the virtual BGF if a transaction cannot be completed.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mg-provisional-response-timer-value minimum 500
  7. Set the maximum value for the number of milliseconds for the gateway controller to wait for a pending response from the virtual BGF if a transaction cannot be completed.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mg-provisional-response-timer-value maximum 2000
  8. Set the default value for the number of transaction pending messages that the gateway controller can receive from the virtual BGF.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mg-originated-pending-limit default 10
  9. Set the minimum value for the number of transaction pending messages that the gateway controller can receive from the virtual BGF.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mg-originated-pending-limit minimum 4
  10. Set the maximum value for the number of transaction pending messages that the gateway controller can receive from the virtual BGF.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mg-originated-pending-limit maximum 20
  11. Set the default value for the number of milliseconds for the virtual BGF to wait for a response to transactions from the gateway controller.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set normal-mgc-execution-time default 1000
  12. Set the minimum value for the number of milliseconds for the virtual BGF to wait for a response to transactions from the gateway controller.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set normal-mgc-execution-time minimum 500
  13. Set the maximum value for the number of milliseconds for the virtual BGF to wait for a response to transactions from the gateway controller.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# setnormal-mgc-execution-time maximum 2000
  14. Set the default value for the number of milliseconds for the virtual BGF to wait for a pending response from the gateway controller if a transaction cannot be completed.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mgc-provisional-response-timer-value default 4000
  15. Set the minimum value for the number of milliseconds for the virtual BGF to wait for a pending response from the gateway controller if a transaction cannot be completed.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mgc-provisional-response-timer-value minimum 1000
  16. Set the maximum value for the number of milliseconds for the virtual BGF to wait for a pending response from the gateway controller if a transaction cannot be completed.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mgc-provisional-response-timer-value maximum 8000
  17. Set the default value for the number of transaction pending messages that the virtual BGF can receive from the gateway controller.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mgc-originated-pending-limit default 10
  18. Set the minimum value for the number of transaction pending messages that the virtual BGF can receive from the gateway controller.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mgc-originated-pending-limit minimum 4
  19. Set the maximum value for the number of transaction pending messages that the virtual BGF can receive from the gateway controller.
    [edit services pgcp gateway bgf-1 h248-properties base-root]user@host# set mgc-originated-pending-limit maximum 100
