LCR Conditions
5-2 Strata DK Programming 5/00
Timeout after 0 (Zero)
Notifies the system of the time delay to the user after dialing a 0, before a regular operator is
accessed.
Area Code and Office Code Exceptions
Separate area code tables and office code exception tables (quantity listed below) can be defined -
one for each available call routing plan. Each table defines the area codes that are handled by the
particular routing plan. According to the tables defined, specific exception office codes can be
routed through a different call plan than the overall area code plan.
Schedule Assignments Call Routing Plans
These plans (quantity listed above) can send the outgoing calls of different groups of stations
according to a time schedule, and call route definitions.
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.
LCR Conditions
If a station has direct line appearances, or Pooled CO Line buttons programmed to allow direct
outgoing line access, LCR is bypassed using the
3RROHG/LQH or a CO /LQH button. LCR
accommodates special code dialing, such as 911 for emergency response, 1-411 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).
Important! Always provide emergency service access for numbers such as 911.
Standard telephones that are Toll Restricted should be required to use LCR to place outgoing calls.
This prevents Toll Restriction defeat when the K4RCU or RRCS times out.
