LEAST COST ROUTING - 3/6 DIGIT
General Description
This service feature allows the system to be programmed to route outgoing calls over the most economical fa-
cility (WATS, FX, DDD). Based on the individual area code and office code dialed (6-digit analysis), the sys-
tem examines the programmed tables and uses the trunk in the order specified.
Station Application
All stations.
Operating Procedure
1. Lift the handset and receive dial tone.
2. Dial the trunk access code and receive dial tone again.
3. Dial the area code, office code and telephone number.
4. The system automatically completes the call using the most economical route.
Service Conditions
1. Least Cost Routing can be programmed to choose a route based on the following criteria:
• Digits dialed (first 3 or 6 digits of the outside number).
• Day of Week
• Time of Day
• Tenant number
• Route Advance
In addition, a special Digit Code Table is used to interpret the one, two, or three leading digits of the area
code: e.g., 01XX....X: International Call; 0: Operator Call; 0XXX: Toll Operator Call. The system exam-
ines the Digit Code Table when an ORT timeout has occured after dialing leading digits.
2. In addition to selecting the route, the system can be programmed to:
• Add the prefix digit 1 for use with FX lines requiring 1+ dialing.
• Add up to 32 digits in front of the number dialed by the station user to allow for equal access accom-
modation, or for secondary common carrier access or Central Offices which do not provide equal ac-
cess.
• Delete the area code (for FX trunks).
• Delete all digits, or up to 8 digits from the number dialed.
• Allow or deny access to a specific trunk route based on the office code dialed.
3. All trunk routes in the system can be accessed using LCR (including DDD, Tie, FX, WATS, etc). Restric-
tion on outgoing calls and Code Restriction assignments are applied.
4. The following programmable tables are available:
• Digit Code Table - Up to 8 tables of area codes are used to determine the route to be selected. Although
area codes are normally 3-digit codes, this table can be assigned with 1 to 8-digit codes. These codes
can be assigned to select any other LCR table.
