Each MF Circuit Group object is a child of an MF Remote Exchange object.
This object contains configuration parameters and status information for an MF circuit group. A circuit group is one or a group of circuits on a DS1. Typically a circuit group is defined for each DS1. Note that a circuit group cannot include circuits from more than one DS1.
A circuit group is defined by the local exchange, the remote exchange, the TDM port, the base timeslot and the number of circuits.
You must configure an MF Media Channel to which the MF Circuit Group can be associated (and the MF protocol profile, incoming call profile and/or outgoing call profile if you are not using the delivered profiles) before you can configure the MF Circuit Group.
For initial configuration of an MF Circuit Group, you need to do the following:
Note that:
Object-Specific Actions | |
Play RMB signal | To play a Reverse Make Busy signal on all active circuits in the Circuit Group, click on the 'Play RMB signal' pushbutton. If this is not possible because one or more of the circuits is carrying an incoming call, the circuit group plays the signal when the call ends. This pushbutton is disabled when Circuit Type is set to Outgoing. |
Cancel RMB signal | To stop playing the Reverse Make Busy signal on all of the circuits in the Circuit Group, click on the 'Cancel RMB signal' pushbutton. This pushbutton is disabled when Circuit Type is set to Outgoing. |
Parameter |
Access |
Description |
Circuit group index | Create | A numeric index identifying the circuit group. |
Description | Change | A text string used in the EMS System Explorer to identify the circuit group. Specify a string of up to 64 characters. |
Circuit type | Change Inactive | Indicates whether the circuits in this circuit group are incoming or outgoing. Values:
|
Media channel | Change Inactive | The MF media channel with which the circuit group is associated. Select from the displayed list of MF Media Channels. (Only active MF Media Channels are displayed.) |
Outgoing call profile | Change Inactive | This field appears only if Circuit type is Outgoing or Bidirectional. The MF Outgoing Call Profile object to be used by the circuit group. Call Profiles are used to determine the format of the outpulsed digit sequence and other call setup parameters. Select from the displayed list of Call Profiles. |
Incoming call profile | Change Inactive | This field appears only if Circuit type is Incoming or Bidirectional. The MF Incoming Call Profile object to be used by the circuit group. Select from the displayed list of Call Profiles. |
MF protocol profile | Change Inactive | The Call Agent MF Protocol Profile object to be used by the circuit group. Select from the displayed list of Call Agent MF Protocol Profiles. |
TDM port | Change Inactive | TDM port to which the circuit group binds. Select from the displayed list of TDM Ports that support MF signaling. |
Base timeslot | Change Inactive | Base timeslot for the circuit group. The base timeslot and the number of circuits defines the range of circuits. Ensure that the range does not exceed the capabilities of the underlying trunk (1-24). |
Number of circuits | Change Inactive | Number of circuits within the circuit group. The range of circuits is defined by the base timeslot and the number of circuits. Note that the range must not exceed the capabilities of the underlying trunk (1-24). |
Dual seizure policy | Change Inactive | This field appears only if Circuit type is Bidirectional. Policy used to determine the dual seizure / glare controlling exchange for circuits within this circuit group. (This should be different from the value used at the remote destination.) Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for this object. Values:
|
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. |
Additional alarm log correlator - Attention Required | Read only | If available, the identifier of the log message for the original 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. |
Additional alarm log correlator - Attend To Dependent | Read only | If available, the identifier of the log message for the original 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. |
Circuit Attention Required alarms | Read only | The total number of Circuits associated with this Circuit Group that are in Attention Required state. |
Circuit Attention Required alarm events | Read only / Reset | The total number of times that the alarm state for a Circuit associated with this Circuit Group has gone to Attention Required. |
Circuit Attend To Dependent alarms | Read only | The total number of Circuits associated with this Circuit Group that are in Attend To Dependent state. |
Circuit Attend To Dependent alarm events | Read only / Reset | The total number of times that the alarm state for a Circuit associated with this Circuit Group has gone to Attend To Dependent. |
Summary child alarm state | Read only | Summarizes the alarm status for all children of this object. Values:
|
Diagnostics - logging - log level | Change | Specifies the level of logs recorded for this object. Logs with a priority equal to or greater than the priority specified are recorded. Set to Default level to use the system-wide default level. Values:
|
Diagnostics - API trace - enabled | Change | Specifies whether API tracing is enabled for this object. Values:
|
Diagnostics - API trace - trace tag | Change | An optional diagnostics tag inserted into API tracing and PD logging for this object. This tag may include any ASCII characters. However, if you want to filter on this tag in the craft interface, do not include spaces or any of the characters ^ \ $ * + ? | ( ) , . ` ' " [ ] { }. |
Requested status | Read only | Specifies whether an administrator has attempted to activate the MF Circuit Group. Values:
|
Actual status | Read only | Specifies the current status of the MF Circuit Group. Values:
