CHAPTER 2. MMC Programming2-292 © SAMSUNG Electronics Co., Ltd.[746] COSTING DIAL PLANThe COSTING DIAL PLAN is used to analyze the leading dialed digits of a dialed numberand determine what DIAL PLAN it is to follow. Data entry for this program is in threefields: ENTRY, DIGITS and COST RATE table reference.DIGITSUp to 500 entries may be made. Each entry can be up to 10 digits. These are the entries thatwill be searched to find a match with the digits dialed by the station making the call.This is a leading digits table and the system will look for the exact leading digits in thetable that match the number dialed. For example, if a user dials 1305 and the COSTINGDIAL PLAN contains 1, 1308 and 1312, the dialed digits will be matched to 1 because1308 and 1312 do not form a complete match. When this table is created by the technicianor when any new entries are added, the system automatically places all entries in numericalorder.Wild cards (∗) can be used to represent any digit. The Toll Restriction Wild Card Characterassignment (MMC 704) is common with Call Costing and Toll Restriction. When allentries are used, [LAST ENTRY] is displayed.DIAL PLANThis shows in the programming display as DP and represents a pattern (1-7, 8). This patternis used by MMC 433, TRUNK COST RATE, to determine the correct billing according toMMC 749, RATE CALCULATION TABLEWhen the system finds a DIAL PLAN match for the digits dialed, the system checks MMC749 to see what RATE CALCULATION to use for costing the call.EXAMPLESWhen a station user dials a number, the system will search the COSTING DIAL PLAN tofind a match. If 13056 is dialed and this MMC contains entries 1, 13, 1305 and 1401, theclosest match is 1305 and this will be selected. If 1305 is dialed and this MMC containsentries 1, 13, 13056 and 1401, no action will be taken until the station user dials anotherdigit. If the next digit is 6, the 13056 entry is the closest match and this entry will beselected, 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 becausethis is the logical order in which the system analyzes digits. Wild cards are checked afterexact digits. If 1813 and 18∗∗ are entered, the system will check 1813 first. If no match isfound, it will check 18∗∗.
