MF Circuit

Each MF Circuit object is a child of an MF Circuit Group object.

The object contains status information for an MF circuit. An MF circuit is an individual timeslot on a DS1. A single MF circuit transfers signaling information and carries voice or data traffic for both directions of a telephone call. MF Circuits are automatically activated when the parent MF Circuit Group is activated so no configuration or activation of these objects is required.

Each circuit is uniquely identified by the local exchange, the DS1 (to which the parent circuit group is associated) and the timeslot.


Parameter

Access

Description
Timeslot Read only Timeslot for the circuit.
Call status Read only Current call allocation status of the circuit. Values:
  • Available for calls
  • Call in progress
  • Releasing call
  • Setting up call
  • Unavailable for calls
Termination status Read only Current termination status of the circuit. Values:
  • Active
  • Inactive
  • Out of service
  • Quiescing
  • Unavailable
  • Unregistered
Reverse make busy status Read only Indicates whether the circuit is currently playing a Reverse Make Busy signal (for an incoming circuit) or detecting a Reverse Make Busy signal being played by the remote exchange (for an outgoing circuit). Values:
  • Playing RMB
  • Detecting RMB
  • None
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 - Attention Required Read only Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero.
Attention Required alarm events Read only / Reset Number of times (since the alarm count was reset) that this object's alarm state has gone to Attention Required.
Alarm log correlator - Attend To Dependent 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 either the Attention Required alarm events or 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 Circuit. This is always set to Active.
Actual status Read only Specifies the current status of the MF Circuit. Values:
  • Active
    The object is active.
  • Failed
    The object was active but has failed.
  • 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.
