Suppose you have changed your mind and decided that you don’t want any fixed digits in your
wildcard prefixes. This allows the mobile user to choose all digits in the wildcard prefix when the
prefix is actually used. To accomplish this, you would program parameters 530–535 as follows:
parameter 530: FF
parameter 531: FF
parameter 532: F
parameter 533: F
parameter 534: F
parameter 535: F
Notice that all four digits used in the wildcard prefixes are wildcard digits.
4. If you want to completely disable the wildcard feature, simply program parameters 530–535 to FF
(hexadecimal FF).
Wildcard Access/Release with Selective Signaling
The wildcard access/release feature can provide added security to the selective signaling feature.
Selective Signaling without Direct Channel Access
In this situation, the PL1877A must receive a mobile access command subsequent to paging the mobile.
If the PL1877A does not receive this command within a specified time period, it normally disconnects
the telephone user.
To prevent anyone except the paged mobile user from answering the call, you can program the PL1877A
to restrict mobile access to users of wildcard access prefixes. Then, you can program the wildcard
template such that wildcard access requires that the mobile users include their capcode digits or user ID
in a wildcard prefix used to answer a page.
For example, if the PL1877A is operating in single mode selective signaling and the mobile user’s
QuickCall II capcode is 023, you can program the PL1877A to allow that mobile user to answer a page
only if they include the digits 0, 2, and 3 in their wildcard access prefix.
If the PL1877A is operating in multi-mode selective signaling and the mobile’s user ID is 56, you can
program the PL1877A to allow that mobile user to answer a page only if the digits 5 and 6 are included
in the wildcard access prefix.
