56 Dialing Plan configuration
•Be careful when choosing how many dialed digits to include in the
SPN. If one of the dialed digits is included in the SPN (that is, ZDP +
one dialed digit), a maximum of ten SPN must be configured for each
branch office. Similarly if two dialed digits are included in the SPN (ZDP
+ two dialed digits), a maximum of 100 SPN must be configured for each
branch office. For each additional dialed digit included in the SPN, the
maximum number of SPN that must be provisioned for each branch
office is increased by a factor of ten.
If a single Access Code that undergoes Zone-based digit manipulation is
used for both on-net and off-net calls,then separate DMI and SPN must be
provisioned to correctly route these calls. The SPN must correctly identify
the routing to be used, and its CLTPfield must set the call type correctly. A
DMI, associated with this SPN, is used to make sure the number stays in
the Private/Special Number domain.
ESN Special Numbers are configured in LD 90. Respond to the prompts as
follows:
•TRAN — Enter the Access Code.
•TYPE — Enter SPN for this configuration, as the ZDP value configured
in step 3 is usually a unique non-dialable number.
•SPN — Enter the ZDP value plus enough digits to distinguish the type
of number, such as national, international, or local. There must be
enough SPN entries to route all valid dialed numbers (see the example
in this section).
•FLEN — Enter the number of digits that are expected for the call type.
•RLI — Enter the RLI configured in LD 86 in step b. The RLI routes the
call to the NRS with the correct type ofnumber.
•CLTP— Enter the type of call defined bythis Special Number: local
(LOCL), national (NATL),or international (INTL).
•For example, assume the following:
AC1 = 1, ZACB = AC1AC1, and ZDP = 101
Customer number = 0
Long-distance calls start with 1, have 11 digits, and use RLI = 10 and
DMI = 10.
Local calls start with 5 or 6, are seven digits long, and use RLI = 30
and DMI = 30.
ATTENTION
RLI and DMI values do not haveto be the same, but for clarity, it may be
useful to set them the same.
