LCR Special Codes
Notifies LCR of special emergency and operator
codes that will be automatically routed as a local call,
without unnecessary delay.
Long Distance information Plan Number
Notifies LCR software how to route a long distan,ce
information call.
Local Call Plan Number
Notifies LCR software which call routing plan is
specifically designed to handle local and special calls.
LCR Timeout after 0 (Zero) is Dialed
Notifies the system of the time delay to the user after
dialing a 0, before a regular operator is accessed.
LCR Area Codes
Up to 16 separate area code tables can be defined for
DK280 systems operating with the RCTUC/D common
control unit (eight for systems with the RCTUA or
RCTUB units); one for each available call routing plan.
Each table defines the area codes that are handled by
the particular routing plan.
LCR Office Code Exceptions for Area Codes
Up to 16 LCR office code exception tables can be
defined with systems operating with the RCTUC/D
common control unit to inform LCR software how to
handle specific office codes within area codes.
According to the tables defined, specific exception
office codes can be routed through a different call plan
than the overall area code plan. Up to eight tables can
be defined for systems operating with the RCTUA,
RCTUBA/BB, or RCTUB common control unit.
LCR Schedule Assignments
Call Routing Plans 1 - 16 can send the outgoing calls
of different groups of stations according to a time
schedule, and call route definitions. The RCTUC/D
common control unit can support up to 16 plans, and
the RCTUA, RCTUBA/BB, and the RCTUB units can
each support eight.
LCR Route Definitions
Groups of CO lines assigned to special common
carriers, foreign exchange lines, or other special
services can be specified as call routes.
LCR Modified Digit Assignments
Carrier codes can be programmed to dial
automatically when a call is placed -over the
appropriate route. Digits can be added to the front or
back of special common carrier codes or other access
numbers to make placing calls an invisible process for
the user. Digits may also be deleted from the front of
the dialed number.
LCR Station Access Priority Assignments
Each station port defined in the system may be
assigned to one of four station priority groups. The
groups can have varying access to the defined call
routes at different times of day. Each group is
partitioned from the other groups.
9.4.2 LCR Conditions
A number of conditions apply to LCR assignment. A
summary of each is listed here. Section 9.6-
Completing the Least Cost Routing Record Sheets,
gives more detailed explanations and examples of
how the conditions relate to the programming process.
If a station has direct line appearances, or Pooled CO
line buttons programmed to allow direct outgoing line
access, LCR will be bypassed using the Pooled line or
a CO line button.
LCR accommodates special code dialing, such as 911
for emergency response, l-411 or 411 for
information, or 800 area code toll-free numbers. These
calls can be directed to the local call route (see
Program 50-31 - 35).
T
IMPORTANT !
Always provide emergency service access for
numbers such as 911.
Basic System Record programs related to LCR
include:
n
n
q
Program 16 defines which outgoing CO lines are
assigned to line groups.
Program 40 denies a station complete line access.
This also applies to LCR.
Program 41 restricts outgoing line calls to selected
stations. These stations may make outgoing calls
through LCR. Automatic Busy Redial (ABR) is
allowed with this program.

Standard telephones that are Toll Restricted should be
required to use Least Cost Routing (LCR) to place
