188 Alternative Routing for DID/DDD
If a match is found, the following call treatments can occur:
• If the number is recognized as an ARRN, Route Selection with the ARLI
defined for the ARRN is performed.
• If the number is in the denied block (such as, SDRR = DENY), standard
call blocking takes place.
• If the number is recognized as terminating at the local switch (for
instance, SDRR = LDID/LDDD), the call is terminated at the station DN
for a DID call, or at the Attendant DN for a DDD call.
Scenario 2
If a match is not found, as in the case of a shorter DN, and the OVLP
package is not equipped, timeout handling occurs resulting in call blocking.
If timeout handling is not set, call blocking does not occur.
Scenario 3
If a match is not found, as in the case of a shorter DN, and the OVLP
package is equipped. The feature then determines if Overlap Sending can
be attempted for this call.
• If Overlap Sending is attempted, the timeout handling flag is set
to.FALSE (OVLL set to 1).
• If Overlap Sending is not attempted, the timeout handling flag is set
to.TRUE (OVLL set to 0)
Note: If Overlap Sending is not active the flag can be reset to.FALSE if
FNP is equipped and FLEN is a non-zero.
If the number is recognized as terminating at a remote system or Central
Office switch (for instance, SDRR = DID/DDD), Route Selection with the RLI
that is defined for that SPN is performed.
Route Selection is performed based on the RLI that is found in the table.
One RLI corresponds to each SPN. Call processing resumes and the call
routes to the Central Office of the terminating Off-net number.
If the route found uses a TIE trunk, then special digit manipulation is applied
so that the proper numbers are outpulsed for the call to terminate at the
station or attendant.
If the route found does not use a TIE trunk, then the call termination is
processed by the current software with digit manipulation, if necessary.
