External Call to Lookahead Interflow VDN
This scenario shows the call flow for an incoming ISDN PRI call to VDN 5008 that 
looks-ahead to VDN 1111 on Switch B (see Figure B-35). The first lookahead 
interflow attempt is denied by Switch B. The second lookahead interflow attempt 
is accepted by Switch B and the call is delivered to and answered by extension 
1567 in ACD split 1444.
Note that Switch A is not guaranteed to receive an ISDN Alerting message from 
Switch B. In these cases, the ASAI adjunct connected to Switch A does not 
receive the Alerting Event Report. The lookahead display information is the VDN 
name provided in VDN administration form and is subject to the VDN display 
override rules.
Assume that VDN 5008 is monitored over CRV 80 by an ASAI Adjunct Processor 
connected to Switch A, and that VDNs 1111 and 1222 are monitored over CRVs 
20 and 26, respectively, by an ASAI Adjunct Processor connected to Switch B. 
Messages in italics refer to messages exchanged by the Switch B and the 
ASAI Adjunct Processor connected to Switch B.
Note that the multiple monitors feature results in events on both the monitors for 
VDNs 1111 and 1222 on Switch B as the call flows from 1111 to 1222 and is 
answered.

							10. Calls Across Multiple Switches
Issue 6 June 1997
B-99
External Call to VDN, Answered by a Local
Station, and Transferred to a Lookahead
Interflow VDN
This scenario shows the call flow for an incoming ISDN PRI call to VDN 5678 
answered by extension 4555 in ACD split 3333 and subsequently transferred to 
lookahead interflow VDN 5008 (see Figure B-36). The call is accepted by the 
receiving switch (Switch B), waits in queue until the vector announcement (VDN 
1222, vector N), and is abandoned by the caller while the call is alerting extension 
1567. The lookahead display information is the VDN name provided in VDN 
administration form.
The transfer to VDN 5008 is completed before the call attempts the lookahead to 
Switch B. If the call had initiated the lookahead interflow before the transfer 
operation had been completed, the ASAI adjunct connected to Switch B would 
have received the extension 4555 as the calling party number instead of the 
original SID/ANI for the call.
Note that the Alerting Event Report received by the ASAI Adjunct Processor 
connected to Switch A is received only if the lookahead interflowed call receives 
alerting treatment (that is, wait hearing ringback/announcement or extension 
alerting) before the call is answered on Switch B. If the call waits with silence (for 
example, wait hearing silence) before Switch B applies ringback or answers the 
call, the ASAI Adjunct Processor connected to Switch A receives a 
Cut-Through/Progress Event Report. Subsequent Alerting and Connected Event 
Reports are provided depending on the call treatment provided by vector 
processing.
The Connected Event Report received by the ASAI Adjunct Processor connected 
to Switch A is triggered by the ISDN Connect message received from Switch B. 
Switch B provides a single ISDN Connect message with the first answer treatment 
provided. For example, listening to music or to an announcement while the call is 
in vector processing will trigger Switch B to send an ISDN Connect message to 
Switch A. Switch B will not send additional ISDN messages to Switch A for 
subsequent answers (for example, other announcements or answered by a 
station). Therefore, the ASAI Adjunct Processor connected to Switch A does not 
receive further answer/connect notifications for the call.
The ISDN called number received by the adjunct connected to Switch A is not the 
same as the VDN number, since ISDN digit manipulation has occurred.
Assume that VDNs 5678 and 5008 are monitored over CRVs 98 and 80, 
respectively, by an ASAI Adjunct Processor connected to Switch A, and that 
VDNs 1111 and 1222 are monitored over CRVs 20 and 26, respectively, by an 
ASAI Adjunct Processor connected to Switch B. Messages in italics refer to 
messages exchanged by the Switch B and the ASAI Adjunct Processor 
connected to Switch B.
