An Overview of Least Cost RoutingLeast Cost Routing (LCR) is used to automatically place calls along the least expensive trunks, depending on the carrier supplying the trunk and the time of dayFor example, if calls to Toronto made between 10 p m and 2 a m are cheapest using a trunk supplied by Al Telecom, LCR automatically routes calls to that city, during that time, along Al Telecom trunks LCR can also be used to add non-dialed digits to (or delete non-dialed digits from) the dialed prefix LCR Trunk GroupsLCR uses 4 trunk groups, each consisting of 4 trunksThe trunks in each group are prioritized according to their cost-effectiveness, so that LCR tries the highest priority trunk in the group first, then the next highest, etc Different LCR trunk groups are used at different times of the dayThe timeof day during which an LCR trunk group is used is determined by the Tiie Priority Route Tables Time Priority Route Tables LCR uses 6 Xme Priority Route Tables to determine which LCR trunk groupsare selected during a certain time of the day Each Time Priority Route Table has three elementsThe elements are l Table Number Time Priority Route Tables are identified by numbers l-6 In DBS 824 programming, the tables are referred to by number l Table Position and Priority - The “position” of a Time Priority Route Table indicates the time of day during which it is used For example, a table assigned to position “1” is used between 7 00 a m and 7 59 am Similarly, a table assigned to position “5” is used between 8 00 am and 4 59 p m LCR provides up to 24 positions for Time Priority Route TablesThe 24 positions are divided among 6 time periods, each time period uses 4 LCR trunk groups For example, trunk groups assigned to positions l-4 are used between 7 00 a m and 7 59 a m - The priority of a Time Priority Route Table is determined by its positionFor example, between 7 00 a m and 7 59 a m , position 1 has the highest priority, while position 4 has the lowest priority The most cost-effective Tie Priority Route Issued 3/l 195DBS 824-l O-400 8-3
An Overview of Least Cost RoutingFF8 Tables are assigned positions that give them the highest priorityLCR tries to use the trunks in the highest-priority position first l LCR Trunk Group Each Time Priority Route Table is assigned to an LCR trunk group Because the Time Priority Route Table is assigned to a time of day (a “position”), the table determines the time that the LCR trunk group is used The cost-effectiveness of a trunk group and the time of day it is to be used determine the position of the Time Priority Route Table Table 8-1Time priority route tabb LCR TablesLCR uses 10 tables of up to 1000 numbers each to determine how to route specific numbers These are the Area Code, Office Code, Special LCR Area Code, and Special LCR Office Code tables Entries in the tables consist of a route table number (l-6) and an area or office code Purposes of the tables are described in Table 8-2 The structure of an LCR table is illustrated in Table 8-3 (xx = route table number) Table 8-2LCR table descriptionsLCR Table “Least Cost Routing 1 (LCR) Area Codes” 1 @age.8-7)“Least Cost Routing (LCR) Office Codes” (Pam 8-8)Purpose Associates area codes with Time Priority Route TablesAssociates office codes with Time Priority Route Tables8-4 DBS 824-l O-400Issued 3/l 195
