■ Suppress a user-dialed prefix digit 1 for 10-digit FNPA calls.
■ Leave a user-dialed prefix digit 1 for 7-digit HNPA calls.
■ Leave a prefix digit 1 on 10-digit calls that are not FNPA or
HNPA calls.
Do not use Prefix Mark 0 in those areas where all long-distance calls
must be dialed as 1+10 digits. Check with your local network
provider.
1
■ Send a 1 on 10-digit calls, but not on 7-digit calls.
Use Prefix Mark 1 for HNPA calls that require a 1 to indicate
long-distance calls.
2
■ Send a 1 on all 10-digit and 7-digit long-distance calls.
Prefix Mark 2 refers to a Toll Table to define long distance codes.
3
■ Send a 1 on all long-distance calls and keep or insert the NPA
(area code) so that all long distance calls are 10-digit calls. The
NPA is inserted when a user dials a Prefix digit 1 plus 7-digits.
Prefix Mark 3 refers to a Toll Table to define long distance codes.
4
■ Always suppress a user-dialed Prefix digit 1.
Use Prefix Mark 4, for example, when ISDN calls route to a switch
that rejects calls with a prefix digit 1.
blank For tie trunks, leave this field blank.
