Pool 892 contains the two Northeastern (Band 1) WATS lines. This pool can on-
ly be used for calls to Massachusetts, Rhode Island, Connecticut, eastern New
York, eastern Pennsylvania, Delaware, Maryland, and Washington, D.C. It is the
least expensive way to make calls to area codes 413,617,401,203,212, 516,718,
914, 717, 215 (except the 465 exchange), 302, 301, and 202.
Pool 893 contains the three cross-country (Band 5) WATS lines. This pool can
be used for calls anywhere in the United States except New Jersey and Hawaii.
It is the second least expensive way to make calls to area codes covered by the
Northeastern WATS lines and the least expensive way to make calls to other area
codes.
WHIZ, the alternate long distance company
for all calls within the United States. It is more expensive than local lines for calls
within area code 201, but less expensive than the local lines tor calls to all other area
codes in the United States and to the nine area codes in Canada to which Primo
employees place calls.
Frank begins to set ARS by separating Primo's line pools into the two categories
UP
shown below. based on the type at dialing for which each line pool should be used.
Line Pools for Toll Call
(Call dials 1 + area code + telephone number)
— Pool 890 (Band 0 WATS lines) for area code 609
— Pool 891 (FX lines)
— Pool 892 (Band 1 WATS lines)
— Pool 893 (Band 5 WATS lines)
— Pool 9 + Other Digits (access to WHIZ)
• Lines Pools for Local Calls
(Caller dials 1 + telephone number or telephone number alone)
— Pool 9 (local lines)
— Pool 890 (Band 0 WATS lines) for area code 201
Frank enters this line pool information in the first two columns of his Automatic Route
Selection Worksheet. In the third column, he circles "T" for each line pool that he
wants used for toll calls and "L." for each line pool that he wants used for local calls.
Setting Up the Default Tables. Frank's next step is to select the default routing pat-
terns for toll calls and for local calls. The default tables, Tables 8 and 9, tell the system
what line pools to use for calls to all area codes and exchanges not listed in Tables
O through 7, To determine which line pools should be the default pools, he jots down
in column 4 of his worksheet:
• The number of area codes for which each of Prime's toll line pools is the most
economical calling method.
• The number of exchanges for which each of Prime's local line pools is the most
economical calling method.
This tells him which line pools service the largest number of different area codes
and exchanges and therefore should be the defaults.
is more expensive than the WATS lines
