CHAPTER 12
LEAST COST ROUTING DATA
1. Least Cost Routing Data Block (Table 12-1)
1.01 The Least Cost Routing Data Block (DLCR
Program) defines the proper outgoing trunk based
on the outside number that is dialed. LCR stores
and examines the number dialed, checking the
area and/or office codes. Based on this examina-
tion and the time of day, LCR chooses the proper
trunk from a programmed route table. The LCR
Data Block has been divided between two utility
programs (DLCI and DLC2).
l
DLCl defines the miscellaneous system para-
meters, the 15 area code tables, and the 16 area/
office tables which further modify the area code
tables.
l
DLC2 defines the 15 route tables, containing six
routes each, and includes three schedules for
time of day selection and 12 Modify Digits Tables.
Each route table's data (DLCl or DLCS) is en-
tered as follows:
REQ (Request)-indicates that the program has
loaded. The only response possible is CHG.

TYPE (Sub-program Type)-There are three sub-
programs within the DLCl Program and two
within the DLC2 Program. The possible re-
sponses are as follows:
DLCI :
PAR (Miscellaneous Parameters
Table)-
Identifies the system operating parameters.
ACT (Area Code Table)-Defines each area
code table.
AOC (Area/Office Code Table)-Modifies
an area code table.
DLC2:
RTB (Route Table)-Defines routes and the
routing selection sequence.
MDT (Modify Digits Table)-Defines the digit
modification that is to be applied to a dialed
number.
Enter: DLCI or DLC2, followed by the de-
sired sub-program:
DLCl: PAR, ACT, or AOC.
DLC2: RTB or MDT.
1.02 After enterin the desired sub-program, press
the return key d '). The prompts associated with
each sub-program will then be issued sequentially.

1. LCR utilities are divided between two programs:
Enter: DLC 1 for: PAR (Miscellaneous Parameters).
ACT (Area Code Table).
AOC (Area/Office Code Table).
DLC2 for: RTB (Route Table).
MDT (Modify Digits Table).
2. If DLCl was entered, the possible responses are PAR, ACT, or AOC. If DLC2 was entered, the
possible responses are RTB or MDT.
