[746] COSTING DIAL PLAN
The COSTING DIAL PLAN is used to analyze the leading dialled digits of a dialled num-
ber and determine what DIAL PLAN it is to follow. Data entry for this program is in three
fields: ENTRY, DIGITS and COST RATE table reference.
DIGITS
Up to 500 entries may be made. Each entry can be up to 10 digits. These are the entries that
will be searched to find a match with the digits dialled by the station making the call. This
is a leading digits table and the system will look for the exact leading digits in the table that
match the number dialled. For example, if a user dials 1305 and the COSTING DIAL
PLAN contains 1, 1308 and 1312, the dialled digits will be matched to 1 because 1308 and
1312 do not form a complete match. When this table is created by the technician or when
any new entries are added, the system automatically places all entries in numerical order.
Wild cards(∗) can be used to represent any digit. The Toll Restriction Wild Card Character
assignment(MMC 704) is common with Call Costing and Toll Restriction. When all entries
are used, [LAST ENTRY] is displayed.
DIAL PLAN
This shows in the programming display as DP and represents a pattern(1-7, 8). This pattern
is used by MMC 433, TRUNK COST RATE, to determine the correct billing according to
MMC 749, RATE CALCULATION TABLE
When the system finds a DIAL PLAN match for the digits dialled, the system checks
MMC 749 to see what RATE CALCULATION to use for costing the call.
EXAMPLES
When a station user dials a number, the system will search the COSTING DIAL PLAN to
find a match. If 13056 is dialled and this MMC contains entries 1, 13, 1305 and 1401, the
closest match is 1305 and this will be selected. If 1305 is dialled and this MMC contains
entries 1, 13, 13056 and 1401, no action will be taken until the station user dials another
digit. If the next digit is 6, the 13056 entry is the closest match and this entry will be se-
lected, but if the next digit is anything other than 6, the 13 entry is the closest match.
Whenever a new entry is added, the system will sort all entries in numerical order because
this is the logical order in which the system analyzes digits. Wild cards are checked after
exact digits. If 1813 and 18∗∗ are entered, the system will check 1813 first. If no match is
found, it will check 18∗∗.
