This step is optional.
Enter the following information.
Parameter |
Description |
Trunk group number | This field appears only if Usage in the previous step is Trunk. The Trunk Group number of the ISDN PRI, used in billing records. When a call is set up using a circuit on this trunk group, the billing record output will indicate the trunk group's number. Range: 0 - 9999. |
Network number | This field appears only if Usage in the previous step is Trunk. An identifier for the remote network, which will appear in transit billing records for outgoing calls to the remote exchange. Specify a different number for each remote network, so that all remote exchanges on the same network have the same network number. Range: 0 - 999999. |
Force echo cancellation on inbound calls | This field appears only if Usage in the previous step is Trunk. Specifies whether the MetaSwitch NE or the remote system should provide echo cancellation for incoming calls on this PRI. Values:
|
Supported call directions | This field appears only if Usage in the previous step is Trunk. Specifies whether this PRI can be used for incoming calls, outgoing calls, or both. Values:
|
Direct IXC connection | This field appears only if Usage in the previous step is Trunk. Specifies whether the remote exchange is a directly connected IXC. Values:
|
Supported bearer capabilities | This field appears only if Usage in the previous step is Access. Types of ISDN call supported by this interface. Select one or more of the following values. The default is all values selected.
|
Channel allocation policy | This field appears only if Usage in the previous step is Access. Channel allocation algorithm on this interface. This should be set to the opposite of the algorithm used by the remote equipment using this interface, to minimize possible conflicts. Values:
|
Far end play ringback | This field appears only if Usage in the previous step is Access. Specifies whether the connected Class II equipment provides audible ringing tone to the caller on voice calls. Values:
|
Calling number required | This field appears only if Usage in the previous step is Access. Specifies whether the connected Class II equipment must provide a calling number (for use in Calling Number Delivery) on call origination attempts over this interface. If you change this parameter while the interface is active, the change does not take effect until the next attempt to originate a call. Values:
|
Trusted | This field appears only if Usage in the previous step is Access. Specifies whether the ISDN PRI is trusted to receive caller ID information or not, if the caller has requested that their ID is withheld. Values:
|
Deactivation mode | Specifies how child objects should be deactivated when deactivating this object. Values:
|
Two B-Channel Transfer - TBCT enabled | This field appears only if Usage in the previous step is Access. Specifies whether the device using this PRI, typically a PBX, can signal to the MetaSwitch NE that it is dropping out of a 3-way call, or transferring a call between two other callers, such that the B-channels it is using for this call are no longer required.
TBCT is supported only for the Telcordia NI-2 ISDN protocol variant; do not set this field to True unless the PRI's Primary Rate Interface Profile specifies this protocol variant. Values:
|
Two B-Channel Transfer - send TBCT notification to controller | This field appears only if Two B-Channel Transfer - TBCT enabled is True. Specifies whether the MetaSwitch NE should signal to the device using this PRI when a TBCT-transferred call ends. This may be required, for example, if the device generates its own billing records and so needs to be aware of the duration of the three-way call or transferred call. Values:
|
Billing - incoming terminating CDR type | This field appears only if Usage in the previous step is Access, or Supported call directions is set to Outgoing. Specifies what additional CDR (if any) is output for incoming calls terminating on this NE using this ISDN PRI. Values:
|
Billing - generate additional incoming call CDR | This field appears only if Usage in the previous step is Access, or Supported call directions is set to Outgoing. Specifies whether an additional 119/0625 billing record should be output for incoming calls that are terminated on the switch, in addition to any CDR configured using the Billing - incoming terminating CDR type field. Values:
|
Billing - incoming tandem CDR type | This field appears only if Usage in the previous step is Access, or Supported call directions is set to Outgoing. Specifies what additional CDR (if any) is output for a tandem call routed through this NE using this ISDN PRI for the incoming leg. Values:
|
Billing - outgoing originating CDR type | This field appears only if Usage in the previous step is Access, or Supported call directions is set to Incoming. Specifies what additional CDR (if any) is output for outgoing calls originating from this NE using this ISDN PRI. Values:
|
Billing - outgoing tandem CDR type | This field appears only if Usage in the previous step is Access, or Supported call directions is set to Incoming. Specifies what additional CDR (if any) is output for a tandem call routed through this NE using this ISDN PRI for the outgoing leg. Values:
|
CNA billing for incoming calls - CIC | This field is visible only if Usage in the previous step is Trunk, Supported call directions is not set to Outgoing, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always. Specifies the Carrier Identification Code to use in CNA billing records generated for incoming calls on this ISDN PRI. Range: 0 - 9999. |
CNA billing for incoming calls - CNA billing number | This field is visible only if Usage in the previous step is Trunk, Supported call directions is not set to Outgoing, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always. Specifies the billing number which may be output in CNA billing records generated for incoming calls on this ISDN PRI. Either leave this field blank, or specify a ten digit number. |
CNA billing for incoming calls - include calling number | This field is visible only if Usage in the previous step is Trunk, Supported call directions is not set to Outgoing, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always. Specifies whether the calling number should be included in CNA billing records for incoming calls on this ISDN PRI. Values:
