OFFICE DATA DESIGN
Procedure for Setting Office Data for OAI Services
3.2 Call ID Notification (SMFN for ISDN)
3.2.1 Functional Outline
This Call ID Notification function is an enhancement of both the Call Termination Notification and the
Answer Notification among Call Status Monitor Facility Notification functions of the OAI system, and
provides the User’s Application Processor for External Computer (UAP) with the caller’s information
when call termination is to be notified about an incoming call from the Integrated Services Digital
Network (ISDN) concerned. Likewise, when the called terminal has answered an incoming call, this
function also provides the UAP with the ISDN caller’s information.
3.2.2 Using Conditions
1. Only when a call has terminated from the ISDN and when the call has been answered, SMFN
message is sent out with the caller’s information added. Note, however, that caller’s information
may not be added to the message depending on the restrictive conditions pertaining to the caller
notification of the ISDN.
2. The number of digits for ISDN caller’s information is maximum 33 for the caller’s number and
maximum 20 for call sub-address.
3. The SMFR cannot monitor ISDN terminal, and thus when a call has terminated to an ISDN terminal
and the call has been answered, SMFN message is not sent out.
