Test Outline:
The tests comprising this NAP are to be performed according to the C.O. Line Number Table provided by the C.O.
If the C.O. Line Numbers are not known, tests cannot be performed because loop-back cannot be performed at the
C.O.
In addition, tests cannot be performed which involve Direct Inward Dialing. Under such circumstances, the C.O.
must be asked to perform an incoming test.
