The ~r command takes up two digit positions in the vector step. This 
works with queue-to-best
 or check-best
 vector steps. No change to 
the vector steps is required for NCR with BSR
.
Trunk Group 
form
0
For Network Call Transfer, the Group Type
 field on the Trunk Group 
form must be set to isdn
 and the Network Call Redirection
 field 
must be set to transfer
. The Supplementary Service Protocol
 
field must be set to g
 and the Network Call Redirection
 field must 
be set to Nortel-transfer
 for MCI DMS250 switches. If the NCT 
feature is subscribed to for the DEFINITY NCR feature, only PRI ISDN 2-
way trunks may be used for the incoming-call trunk groups to be 
administered for vectoring activation of NCT, since the software selects a 
trunk from the same trunk group to set up the second leg call. Refer to

On the DEFINITY Best Service Routing Application form, the Net 
Redir?
 field must be set to Y
 for each location to which calls are to be 
directed using NCR. Refer to the following figure.
The number administered in the interflow VDN field on the Best Service 
Routing form (or in the ~r vector step on the Call Vector form) should 
not 
have any ARS prefix or trunk access code. Some PSTN numbers will 
need to include the long-distance access code. Contact your PSTN for 
specific information.

Interflow applications replaced by NCR, supplementing BSR 
applications, on the 
DEFINITY Call Vector form, the leftmost position in 
the route-to

page) must be set to ~r
 for each vector that will invoke NCR.
The number administered in the ~r vector step on the Call Vector form 
should 
not have any ARS prefix or trunk access code. Refer to the 
following figure.

							Troubleshooting and Things to Know
22 DEFINITY® ECS R8.3 What’s New: Network Call Redirection
Troubleshooting and Things to Know0
Overview0This section contains basic information on troubleshooting, as well as 
important information about administering NCR.
Troubleshooting0General troubleshooting of NCR can be accomplished by using:
•the ISDN message trace information provided by the Message 
Sequence Tool (MST)
•Vector events displayed by the display events DEFINITY 
system administration command.
•To see the behavior of a particular VDN or vector, use the list 
trace vdn and/or list trace vector commands to check for 
NCR errors.
•To check for NCR errors using BSR processing, enter the ch MST 
switch administration terminal command to set the BSR and vector 
fields to Y, and use the enable mst and the list mist cont 
switch administration terminal commands to see NCR-related MST 
trace data.
•To see NCR-related BSR peg counts, enter the go tcm switch 
administration terminal command or enter the rdd :dpm_mgr 
Bsr_appl_loc command to see NCR-related BSR attempts, 
int errors, net errors, redirs, and discs peg counts.

troubleshooting
0
If NCR vector activation fails, use the display events
 switch 
administration terminal command to check for the following NCR vector 
events:
•NCR: Invoke trunk not ISDN
•NCR: Bad NCR trunk admin
•NCR: No NCT PSTN service
•NCR: No NCT outgoing trk
•NCR: NCT outgo trk drop
•NCR: PSTN NCT invoke err
•NCR: PSTN NCT netwrk err
•NCR: Used NCT trk-to-trk
•NCR: No NCD PSTN service
•NCR: NCD invalid PSTN nmbr
•NCR: NCD call connect err
•NCR: PSTN NCD invoke err
•NCR: PSTN NCD netwrk err
•NCR: PSTN NCD max redirs
•NCR: PSTN NCD no disc
•NCR: Internal system err 
						

							Troubleshooting and Things to Know
24 DEFINITY® ECS R8.3 What’s New: Network Call Redirection
Things to know0The following important items should be known.
Failures0Failures can occur in NCR after the queue-to-best
 vector command is 
executed. Vector steps are not used to log vector events (this happens 
automatically), so vector steps following the queue-to-best
 command 
are needed to provide alternate call treatments. To prepare for this, use 
one of the following:
•If the second leg of the call cannot be set up, use the second 
vector step to log the event that caused this. Administer the 
second vector step to anticipate this problem by administering it to 
record call failure events.
•Try to invoke Network Call Transfer. If Network Call Transfer is 
invoked and the public network rejects the call, the call should revert 
to a trunk-to-trunk transfer. In this case, the call is not lost.
NCT0With NCT, the transferring vector may or may not answer the first leg of 
the call before redirecting the call over the public network. The vector can 
set up the second leg of the call before answering the first leg, but the 
public network cannot redirect the call until the first leg is answered. If the 
call has not been answered, DEFINITY will answer the call before 
requesting NCT.
NCD0With NCD, no steps in the vector can answer the call when it is being 
redirected, or the redirection will not occur. In other words, vector steps 
must not answer the call before requesting NCR.
Current offerings for NCD will not “clear the call on alerting.” 
Announcement 
Vector Steps
0
At this time, announcement vector steps cannot be used with NCD before 
NCD is to be invoked. Announcement vector steps can be used in 
following vector steps if NCD fails. Announcement vector steps can be 
used with NCT.
