■ a Route End event for any active Route Select dialogue. The client does
not need to do anything.
If all links to a switch go down or are blocked, service to the switch becomes
unavailable and the G3PD sends a CSTA Universal Failure event for any new
CSTA requests. The error code is set to RESOURCE_OUT_OF_SERVICE (34).
In this situation, the client application could make use of System and Link Status
Notification to determine when service is restored.
If these problems persist, contact Services.
How Dropped Link Affects Open Streams
When a PBX has multiple links configured and one link goes out of service,
service to the affected switch can still be available if another link is available to
provide service. Service remains available to any previously opened streams,
and to any new acsOpenStream() requests.
If all links to a PBX become unavailable, any previously opened streams remain
open until either they are closed or the G3PD unloads. The client does not
receive a specific message stating that service is unavailable unless system
status event reporting has been requested via the API call, cstaSysStatStart().
If service becomes unavailable (because all links are down), any subsequent
Telephony Services requests over any open streams receive a CSTA Universal
Failure event (RESOURCE_OUT_OF_SERVICE (34)).
Any attempts to open a stream to a PBX that has no links available result in an
ACS Universal Failure message with the error code set to DRIVER_LINK_
UNAVAILABLE (1007).
Tserver Error Log
The Tserver Error Log provides a common log for viewing the errors generated by
the Tserver, the G3PD, and any other PBX driver that chooses to log to this file.
Following are the kinds of errors you may find during installation of the G3PD.
The Services Organization maintains a complete list of specific errors and
troubleshooting messages.
NOTE:
When viewing error files on the Tserver, do not use MS Word for Windows.
This editor can prevent the Tserver from accessing the file (this is the only
editor known to affect the Tserver).
