Complete the following steps to change parameter values in a .pf file:
Step |
Action |
1 |
Modify the value in the corresponding .par file. |
2 |
Initialize the NaturalAccess PRM service so the binary parameter file is loaded. |
3 |
Parse the .par file. |
4 |
Do one of the following:
|
Parameter modification must take place before nccStartProtocol is called to start the TCP (as described in Starting a TCP on a context). When the function call is made, the TCP is programmed as specified by the parameters.
The following tables list the parameters in the nccxidsn.pf parameter file. Changing these parameters directly affects call control messages (for example, messages associated with NCC API functions). To change these parameters correctly, you must have knowledge of the ISDN specifications for the target country. See Using extended parameters for more information.

Field name |
Default |
Units |
Description |
---|---|---|---|
exclusive |
1 |
integer |
Determines if this TCP runs in exclusive mode or non-exclusive mode. For details, see B channel assignment overview. 0 - Non-exclusive mode |
direction |
0 |
integer |
Determines if the channel is inbound, outbound, or bidirectional. See B channel assignment overview. 0 - bidirectional (default) |

defaulttone |

startCP |
1 |
integer |
If this parameter is set to 1, the TCP starts call progress when it receives a SETUP ACKNOWLEDGED, PROCEEDING, or ALERTING message, which contains a progress descriptor field or PROGRESS message, whichever comes first. If none of the listed messages arrive, call progress is started when CONNECTION CONFIRMATION is received, if the application does not want to connect on signal. If this parameter is set to 2, the TCP starts call progress on the first call establishment message (SETUP ACKNOWLEDGMENT, PROCEEDING, ALERTING, or PROGRESS) received back from the network, regardless of the progress descriptor. If this parameter is set to 0, call progress is not started. |
flags |
0x1121 |
mask |
Flags (defined in nccxisdn.h) that determine when to send PROGRESS, CALL PROCEEDING, or ALERTING messages. The values can be ORed for cumulative effect. See Flags field settings. |
blockrejectmode |
0 |
integer |
How to reject calls when the channel is blocked with BLOCK_REJECTALL mode: 0 - reject immediate |
blockwaittime |
3000 |
ms |
Sets the maximum time to wait for the application to respond for an incoming call, before playing a default tone. |
ISDNeventmask |
0x0000 |
mask |
ISDN informational event mask (defined in nccxisdn.h). ISDN_REPORT_PROGRESS indicates that ISDN progress messages are being received. |
For more information about how parameter files are installed, see the Dialogic® NaturalAccess™ ISDN Software Installation Manual.
Flags (defined in nccxisdn.h) that determine when to send PROGRESS, CALL PROCEEDING, or ALERTING messages. The values can be ORed for cumulative effect.
