rate LCR route plans. They are
Programs 51 w 54.
The purpose of the plan scheme is to provide the
system with directions for routing all possible calls,
made by all possible users at all possible times of
day. Eight separate plans provide the customer
flexibility enough to route different area codes and
exception officecodes over different CO linegroups.
7.32 Initialized data assigns all calls to plan eight.
Any assignments made in
Programs 51 w 54
for
plans 1 - 7 will exempt the defined call from being
made on route plan 8. Likewise, any phone num-
ber not specified in routes 1 - 7 automatically
defaults to route plan 8.
its Area Code Table.The home area code
must be entered into one of the eight avail-
able LCR route plans through Program 31).
Thus, LCR is informed of how to handle local
calls. Typically, systems are configured to have
the LCR route plan containing the home area
code as the same as the local route plan
defined in Program 50-5. This usually is pro-
grammed by the installer to be route plan
number I, rather than the default plan 8.
7.33 Tables for
Programs
51- 54 appear on LCR
Route Plan Numbers 1 - 8. The following instruc-
tions reveal how to fill in individual tables within the
plans. Each of the following program tables must
be completed for all plans.
7.34 Program
51- LCR Area Code Tables:
Every route plan can be assigned to define a set of
area codes and/or office codes.
l
The purpose of
Program 51
is to define which
area code calls are placed over which LCR
Plan Number (1 - 8). Initialized data assigns all
possible area codes (000 - 999) to LCR Plan
8. Therefore, calls made to all area codes will
be routed over route definitions defined in
Program
54 for plan 8, following the time
schedule specified by
Program
53 for plan 8
(unless other assignments are made in plans 1
- 7).
7.35 Program 52-LCR Office Code Excep-
tions for Specified Area Code:
The purpose of
the Office Code Exception Table is to enable the
customer the flexibility of routing specific office
codes through a different call plan than other office
codes used with that area code.
l
Eight LCR office code exception tables may be
defined for the overall LCR scheme. Any num-
ber of exception code tables may be assigned
to each route plan, although each exception
table may only be used once system-wide.
l
Every route plan can be assigned to define a
set of area codes and office code exceptions or
a set of office code exceptions.
l
This program applies to both examples listed
below. In the first case, an office code excep-
tion table does not need to be defined in
addition to the area codes in
Program 51,
but
it may. In the second case, the plan may only
pertain to exception office codes for certain
area codes.
l
For example, any area code entered in a
Program 51
LCR area code table for plans 1 -
7 is subtracted from plan 8. An area code
cannot be lost. If it is subsequently deleted
from plans 1 - 7, LCR software automatically
adds it to plan 8.
l
To fill in record sheets for plans 1 - 8:
l
Check the box by Area Code Table.
l
Enter the applicable area codes, three
digits per box.
NOTE:
Remember that LCR matches the home area
code entered in Program 50-Z with the LCR
route p/an containing the home area code in
Example
l-In the first example, office code ex-
ception tables will be defined to the area code
table. Use the continuation sheet to define the
exception office codes. As many as eight of the
office code exception tables may be linked to a
plan, but each exception table may only be used
once. When using the continuation sheet, be
sure that the same exception table is not as-
signed to more than one plan.
l
Turn to the continuation sheet (that follows
plan 8 record sheet).
l
Determine the plan number where the ex-
ception office codes will be rooted.
l
Fill in the area code of the exception office
codes in the spaces provided by the cor-
rect plan number. These office codes will
