BRI Port Parameters

Datalink:
[datalink] This parameter specifies whether to configure the port's call switch for a point-to-point or point-to-multipoint circuit. Valid values are:
Auto Detect - Automatically detect the datalink setting.
Point to Point - Configure for a point-to-point circuit.
Point to MultiPoint - Configure for a point-to-multipoint circuit.

Call Type:
[call_type] This parameter specifies the call type for outbound calls.
Auto - Makes a call using the modem type. If this fails with a cause code greater than 31, then the call will automatically be retried using voice call type.
Modem - Makes a modem (3.1 kHz audio) call.
Voice - Makes a voice call.
The modem type provides for a higher quality audio path; however, this facility is not available at all numbers. In cases where the party being called cannot accept a modem call type, the voice call type should be used.

Max DID Digits:
[max_did_digits] This parameter specifies the maximum number of DID digits to wait for before accepting an incoming call. Set this parameter to '0' to disable waiting for DID digits. The system reports all of the DID digits to the application even if the number of received DID digits exceeds the number specified for 'Max DID Digits'. Use the did offset parameter to strip digits from the string before the system passes them to the application.

Max DID Timeout, sec:
[did_timeout] This parameter specifies the maximum timeout (in seconds) allowed before processing the call after assuming receipt of the last DID digit. Value 0 indicates no waiting time.

DID Offset:
[did_offset] This parameter specifies the number of digits to be removed from the beginning of the DID digits string received from the network.

Advanced Settings

Channel 0 Default CallerID:
[default_caller_id_channel_0] This parameter specifies a string of up to 15 characters that provides the default caller ID (ISDN calling party number) to be used when placing outbound calls on channel 0. If the user application provides a caller ID when placing a call, the system ignores this field.

Channel 1 Default CallerID:
[default_caller_id_channel_1] This parameter specifies a string of up to 15 characters that provides the default caller ID (ISDN calling party number) to be used when placing outbound calls on channel 1.

Set the parameter to 'Number not available' when connected to a public network.

Redirect as Calling Party:
[redirect_as_calling_party] This parameter specifies whether or not to redirect the number as a calling party number to the application. Set the parameter as follows:
No - Causes the system to use the original calling party number as the number reported to the application.
Yes - Causes the system to use the redirect number as the calling party number reported to the application. Selecting this option removes any association between the original calling party number and the call.

Reject Incomplete DID Digits:
[reject_incomplete_did] This parameter specifies the action to take when the number of DID digits received from the incoming call is less than the number of digits specified for the 'Max DID Digits' field. Set the parameter as follows:
No - Sends an alerting or proceeding message to the network and reports the call to the application even if the number of received DID digits is less than the 'Max DID Digits' value. The system takes this action when the number of digits collected remains incomplete after the 'DID Timeout' period or when it receives a sending complete informational element (IE).
Yes - Sends the network a reject message that causes the network to drop the call. The application does not receive any notification of the call.

Screening:
[screening] This parameter specifies whether the port provides and validates the calling party number passed to the called party. Valid values are:
User not screened - Indicates that the port provides the calling party number without validating it.
User verification passed - Indicates that the port provided the calling party number and passed a successfully validated number to the called party.
User verification failed - Indicates that the port failed to validate the calling party number.
Network Provided - Indicates that the network validates the calling party number.
