The PBX Line object defines one of the group of physical telephone linesor Configured SIP Bindings that connect the PBX to the NE, and specifies how it is used. It is a child of the PBX Lines object.
A PBX line that uses a Configured SIP Binding can support multiple concurrent telephone calls, so you may only need one PBX Line if the PBX uses SIP. You can configure two or more PBX lines if required, but they must use different Configured SIP Bindings, with a different contact IP address / port combination on each binding.
To configure and enable a PBX Line, you need to do the following:
Parameter |
Access |
Description |
Configured SIP Binding | Change Inactive | This field appears only if the Call Agent signaling type field on the PBX object is set to SIP. Specifies the configured SIP binding that this PBX Line uses to connect to the NE. To specify a configured SIP binding, click on the search button at the end of the field to select from a list of configured SIP bindings for which the Usage field is set to Subscriber. As a short-cut to select the Configured SIP Binding, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. For more details, refer to the description of the Details panel in Operations Manual: Overview. |
Maximum call appearances | Change | This field appears, and must be supplied, only if the Call Agent signaling type field on the PBX object is set to SIP. The maximum number of simultaneous call branches in which this PBX Line can participate. The actual maximum number of simultaneous call appearances may be limited by the maximum value specified on the Configured SIP Binding that this PBX Line uses, if this is lower, especially if two or more PBX Lines (on different PBXs) use the same binding. Choose Use default to use the default value specified on the parent PBX (or in its Persistent Profile), or specify a value. The default is 64. |
PBX Line usage | Change Inactive | Specifies which types of incoming calls are accepted on this line. This allows you to allocate one or more lines to the PBX for specific purposes, for example to ensure that a certain number of lines are always available for calls to the switchboard operator or for Direct Inward Dial.
This field appears only if the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS. Values:
|
Gateway | Create | The Trunk / Access Gateway or Subscriber Gateway that owns the Access Device that this line uses to connect to the NE. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. Click on the search button at the end of the field to choose from access devices on Trunk / Access Gateways or access devices on Subscriber Gateways. Then select from the displayed list of gateways of the specified type. As a short-cut to select the gateway, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. For more details, refer to the description of the Details panel in Operations Manual: Overview. |
Access Device | Create | The Access Device that this line uses to connect to the NE. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. Click on the search button at the end of the field to choose from Access Devices on the gateway specified in the Gateway field. If the gateway contains only one Access Device, this device is selected automatically and there is no need to change it. As a short-cut to select the Access Device, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. For more details, refer to the description of the Details panel in Operations Manual: Overview. If you have not selected a gateway in the Gateway field, the match details are used to match against all Access Devices that are children of Trunk / Access Gateways. |
Access Line number | Create | This field appears only if the Number status field on the PBX object is set to Normal, Ported to, or Non-geographic and the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS. The Access Line number on the specified Access Device that this line uses.
Either type in the number (which must not match the access line number used by any other subscriber on this access device), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use.
The highest line number that you can specify depends on the access device type: for an IAD it is the number of voice ports configured, and for other devices it is a configured parameter on the access device.
If you click on the ellipsis symbol, the dialog box that appears offers 'manual selection' or 'automatic selection'.

ISDN Interface | Change Inactive | This field is valid only in the US. |
Cascade fault monitoring level on apply | Change | This field is valid only in the US. |
ISDN default bearer capabilities | Change Inactive | This field is valid only in the US. |
Signal function code | Change Inactive | This field appears only if the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS. The subscriber's signal function code which is used for CAS signaling. Values:
|
Line usage | Change Inactive | Specifies whether the subscriber intends to use this line for voice, fax and/or modem calls, or exclusively for fax and modem. This controls the use of data encoding and compression on the line. Note that support for T.38 fax encoding depends on the Remote Media Gateway Model being used, and on the T.38 support setting in the Call Agent.
This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Values:
|
FSK format | Change Inactive | The type of FSK tones used to pass Caller ID messages to this line. This field appears only if the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS, and does not appear if the subscriber uses an access device on a Subscriber Gateway. Values:
|
Line side answer supervision supported | Change Inactive | Specifies whether Line Side Answer Supervision is supported for this line. This field appears only if the Call Agent signaling type field on the PBX object is set to Analog line/T1 CAS. Values:
|
PBX plays ringback | Change Inactive | Specifies whether the PBX provides audible ringing tone to the subscriber. Values:
|
PBX plays dialtone | Change Inactive | This field appears only if the grandparent PBX object has a Call Agent signaling type of Analog line/T1 CAS.
Specifies whether or not the PBX provides a dialtone to the susbcriber. Values:
|
Fault monitoring level | Read only | Specifies whether alarms raised for this PBX Line are suppressed, so that the EMS does not display them or send them to SNMP alarm notification destinations. You may want to do this if you expect alarms from this subscriber (for example if the object is currently being provisioned or undergoing maintenance), so that it is easier to see unexpected alarms from other objects. The value shown here is taken from the parent PBX object and you cannot change it. Values:
|
Alarm state | Read only | Specifies whether any alarms are currently raised for this subscriber. Values:
|
Alarm log correlator | Read only | Identifier of the log message that was generated when this subscriber last entered Attention Required or Attend To Dependent alarm state. This field is reset when the Attention Required alarm events and the Attend To Dependent alarm events are reset to zero. |
Additional alarm log correlator | Read only | If available, the identifier of the log message for the original event that caused the last Attention Required or Attend To Dependent alarm state for this object. This field is reset when the Attention Required alarm events and the Attend To Dependent alarm events are 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. |
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. |
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:
|
