a particular pool, enter the appripriate absorption numbner in the same
row as the pool number, in the column headed "Absorb."
Assign a value of 0 if you do not want absorption. Assign a value of 1-11
according to the number of digits you want absorbed, starting with the
first digit dialed.
Example: If a company has FX trunks for the 686 exchange in the 901 area
code and wants to allow people to dial those calls the same way they dial toll
calls to other area codes, an absorption number of 4 is assigned to the FX trunk
pool, Pool 893. The completed form for the 6-Digit Table that routes calls to the
FX trunk pool is shown in Figure 4-6.
