MF Media Channel

Each MF Media Channel object is a child of an MF Remote Exchange object.

This object contains configuration parameters and status information for an MF media channel. A media channel is defined for a set of circuit groups with the same local exchange and the same remote exchange and typically the same quality of service. A media channel is uniquely identified by the local and remote exchanges and a media channel index.

Each media channel maintains a list of the associated circuit groups. Each associated circuit group references its associated media channel using the media channel index.

Routes are defined using media channels rather than individual circuit groups because it generates simpler routing tables.

You cannot define an MF Media Channel for a one-way incoming trunk; it is required only for two-way or one-way outgoing trunks.

For initial configuration of an MF Media Channel, you need to do the following:

Note that a Media Channel cannot be deleted while it is referenced by a Circuit Group. A Media Channel can be deactivated while it is referenced by an active Circuit Group; this does not affect any of the currently active calls in that Circuit Group, but will prevent any further calls being routed over that Circuit Group.


Parameter

Access

Description
Media channel index Change Local index identifying the media channel. This index is referenced by the circuit groups which are associated with the media channel.
% utilization Read only Percentage utilization of the media channel. This is calculated by dividing the number of allocated circuits by the total number of circuits in the media channel and multiplying the result by 100.
% utilization of allowed circuits Read only Percentage utilization of the circuits that the local exchange is allowed to allocate in the media channel. This is calculated by dividing the number of circuits allocated by the local exchange by the number of circuits the local exchange is allowed to allocate and multiply the result by 100.
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention.
  • Attend To Dependent
    Attention Required elsewhere - another object on which this object depends is not operating normally.
Alarm log correlator Read only Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero.
Attend To Dependent alarm events Read only / Reset Number of times (since the alarm count was reset) that this object's alarm state has gone to Attend To Dependent.
Alarm state changed timestamp Read only The time at which the Alarm state last changed.
Alarm events reset timestamp Read only The time at which the Attend To Dependent alarm events was last reset to zero.
Requested status Read only Specifies whether an administrator has attempted to activate the MF Media Channel. Values:
  • Active
    The object has been activated.
  • Inactive
    The object has not been activated or has been deactivated.
  • Disabled
    The object has been disabled.
Actual status Read only Specifies the current status of the MF Media Channel. Values:
  • Active
    The object is active.
  • Going Active
    Activation is in progress.
  • Going Inactive
    Deactivation is in progress.
  • Inactive
    The object is inactive.
  • Disabled
    The object has been disabled.
  • Activation Failed
    The object is inactive because an activation attempt has failed.
  • Failed
    The object was active but has failed.
  • Quiescing
    The object is preparing for normal deactivation. It is operating normally but will not accept any new users.
  • Waiting For Parent
    The object cannot be used because its parent object is not yet active.
  • Parent Failed
    The object cannot be used because its parent object has failed.
