Discard Digits
Description:
When the digital telephone system is installed behind a host system such as a PBX or
CENTREX, users must dial access codes before obtaining an outside line dial tone. To
ensure that the system costs a call on just the actual telephone number that the user dials,
you should arrange for the system to ignore these access codes. You can program up to
six different access codes entries with up to eight digits per entry.
Example: If the system is installed behind a PBX using a 9 as an outside line access
code, program a 9 as the discard digit. When a number such as 9-555-1212 is dialed,
the 9 is discarded and the call is costed based on 555-1212.

1. Dial 75.
