Programming Wildcard Access/Release
The wildcard access prefixes can be programmed to be from 1 to 6 digits long. However, they cannot be
of variable lengths - if this feature is programmed for 3-digit wildcard access prefixes, then all wildcard
access prefixes (and corresponding wildcard release suffixes/ prefixes) must only be three digits long.
Also, some of the digits can be set to specific values.
For example, you can program the PL1877A such that all wildcard prefixes are in the form of x3x where
x is a wildcard digit chosen by the mobile user. In this case, the user can access the PL1877A only with a
3-digit access prefix in which the second digit is 3.
Suppose you have decided that wildcard access codes will be four digits long, and take the form of 3xx2,
where the x represents wildcard digits selected by the mobile user.
Program required values into the Wildcard Access/Release Code using #’s where you want the wildcard
digits (3##2 in this example).
Suppose you decide you don't want any fixed digits in the wildcard prefix. In the four-digit example
above, you would enter ####.
