Allow access Specifies whether connection requests from devices
whose addresses are listed will be accepted (Y) or
rejected (N).
If you enter Y, calls will only be accepted from
devices whose addresses you list on this screen. If
you enter Y and do not list any addresses, all calls
will be rejected.
If you enter N, calls will only be rejected from devices
whose addresses you list on this screen. If you enter
N and do not list any addresses, all calls will be
accepted.
If you do not update this screen (data flag is N, a
default PAD security will be downloaded that allows
all calls to be accepted.

be accepted for connection if Allow access is Y or
rejected for connection if Allow access is N. Enter
up to 32 remote addresses per screen and up to 512

You can use the letter X as a wildcard character in
place of any single digit. All systems with
corresponding addresses will have the same access
rights. The address check is sensitive to the length of
the address. To manage addresses, you may enter
pyramids of Xs where the base is the longest
expected address and the peak is the shortest
expected address.

digits starting with 6789:
