Information Exchange Event Notification via the LIG

Date Posted: October 12, 1999

Customers affected: All Information Exchange event notification dial-out users.

This Technical Bulletin contains information about changes to the Information Exchange event notification dial-out feature, planned for implementation on October 17, 1999. Information Exchange is the mailbox component of Interchange Services.

Use of Local Interface Gateways
Currently, Information Exchange utilizes IN Gateways to process event notification dial-out requests. IBM(R) is replacing the use of IN Gateways with Local Interface Gateways (LIGs) as part of IBM's preparation for Year 2000.

Event Trail changes
As a result of the move from Gateways to LIGs, changes will appear in the event trail for event notification dial-out requests. Requests that result in any of the following conditions will appear in the event trail as "CLIENT ERROR":

• The user's Event Notification Manager (ENM) picks up but does not respond (Event trail currently reads NO PARTNER RESPONSE)
   
• A connection was made with the user's ENM, however the connection was lost prior to completion of the request (Event trail currently reads LOST CONNECTION)
   
• The number dialed is not a modem (Event trail currently reads WRONG NUMBER)
   
• The number dialed is busy (Event trail currently reads NUMBER BUSY)
   
• The number dialed did not answer (Event trail currently reads RING NO ANSWER)

There are limitations in the LIG node that prevent Information Exchange from providing a more detailed event trail status at this time.

In addition, two new event trail status codes may appear in the event trail, as follows:

• NO SRVR CONNECT - A connection with the LIG could not be established. A backup LIG was also tried.
   
• NO SRVR CONVRSE - A connection was established with the LIG but Information Exchange could not send the request via the connection.

Event trail status definitions in the Information Exchange Administration Services Supplement (GN10-4073-00) that reference a Gateway may also apply to the LIG. The definitions in this publication will be updated with the next major release of Information Exchange.
