B-86Issue 6 June 1997 
10. Calls Across Multiple Switches
This section presents several scenarios for calls routed, transferred, or 
conferenced across switches. Figure B-32 shows the VDNs, vectors, splits, and 
extensions for the following scenarios. Each switch has its own ASAI link, but 
ASAI links are not shown in the figure.
NOTE:
Section 15 gives examples of calls between switches using UUI.
The trunk groups that are connected between Switch A and Switch B in this 
scenario should be administered as non-DCS. See the DCS discussion in 
Chapter 12, “ASAI and Feature Interactions” in the 
DEFINITY Enterprise 
Communications Server CallVisor ASAI Technical Reference.

							10. Calls Across Multiple Switches
Issue 6 June 1997
B-87
External Call to VDN, Answered by Station and
Transferred to a VDN on Another Switch
This scenario shows the call flow for an incoming ISDN PRI call to VDN 5678 
answered by extension 4555 in ACD split 3333 (see Figure B-33). The agent at 
extension 4555 manually transfers the call to VDN 1222 in Switch B. Extension 
1567 in ACD split 1444 answers the call at Switch B.
The scenario shows the agent at extension 4555 completing the transfer 
operation while the call is in queue at ACD split 1444. Note that no Alerting or 
Connected Event Report is sent to Switch A, because the call to Switch B 
(call_id 45) is not monitored on Switch B until it is merged with the incoming call 
(call_id 37). If agent 4555 completed the transfer after talking to agent 1567, the 
Call Transferred Event Report would have occurred after the Connected Event 
Report was sent by Switch B. All other parameters would have remained the 
same. Similarly, if the operation is a conference instead of a transfer, the Call 
Transferred Event Report would have been replaced by a Call Conferenced Event 
Report.
Assume that VDN 5678 is monitored over CRV 98 by an ASAI Adjunct Processor 
connected to Switch A, and that VDN 1222 is monitored over CRV 26 by an ASAI 
Adjunct Processor connected to Switch B. Messages in italics refer to 
messages exchanged by Switch B and the ASAI Adjunct Processor 
connected to Switch B.

							10. Calls Across Multiple Switches
Issue 6 June 1997
B-91
External Call to VDN, Answered by Station, and
Transferred to a Station on Another Switch
This scenario shows the call flow for an incoming non-ISDN call to VDN 5678 
answered by extension 4555 in ACD split 3333 (see Figure B-34). The agent at 
extension 4555 does a consultation transfer to extension 1567 on Switch B. That 
is, the transfer is completed after the agent on extension 4555 talks to the agent 
on extension 1567. The trunks between switches are ISDN PRI trunks. 
Assume that VDN 5678 is monitored over CRV 98 by an ASAI Adjunct Processor 
connected to Switch A and that extension 1567 is domain-controlled over CRV 45 
by an ASAI Adjunct Processor connected to Switch B. Messages in italics refer 
to messages exchanged by Switch B and the ASAI Adjunct Processor 
connected to Switch B.
