Once he has setup both default tables, Frank goes on to plan tables to route calls
to specific area codes and exchanges for which Primo has low-cost line pools.
Setting Up 6-digit Tables. Frank begins by checking his list of line pools to see what
6-digit tables he needs to set up. These are tables that route toll calls to specific ex-
changes within an area code. The only 6-digit table he needs is a table to route calls
to the 465 exchange in area code 215, for which Primo has FX lines.
Frank makes this 6-digit table Table 0. If he needs to set up more 6-digit tables in
the future as Primo adds more special-purpose lines, he will number them 1,2, etc.,
keeping his 6-digit tables together as ARS requires. He enters the Philadelphia area
code, 215, in the 00 position in the Area Code/Exchange section of the form for Table
0. Next, he enters 465, the exchange served by the FX lines, in the 01 position.
Since these calls should be placed on the FX lines, Frank writes down "891," the
code for the FX line pool, as his first entry in the Pool column of Table 0. He then con-
siders whether he needs to associate an absorption code with this line pool. He does,
since employees must dial the complete n-digit telephone number to reach the
Philadelphia suppliers, but the system places the call by dialing only the last 7 digits.
Frank enters "3" at the top of the Absorb column. As a result, when callers dial 1,
then 215, then a number beginning with 465, the system absorbs the first four digits
and dials just the 7-digit number, as required to use one of the FX lines.
Finally, Frank considers whether another line pool should be used for calls to this
area code and exchange if the FX lines aren't available. Since the Northeast (Band
1) WATS line is also an acceptable method for placing these calls, Frank makes "892"
his second entry in the Pool column of Table 0. He doesn't associate an absorption
code with Pool 892, because the system dials the same digits as the caller to place
a call on the Band 1 WATS lines.
