Wildcard Access/Release with Paging
This feature can provide added security to paging.
Paging without Direct Channel Access
In this situation, the PL1877A must receive a wildcard access command after the mobile is paged. If this
command is not sent 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 code
such that wildcard access requires the mobile users include their capcode digits or user ID in a wildcard
prefix to answer a page.
For example, if the PL1877A is operating in single mode paging and die mobile user’s 2-tone capcode is
023, the PL1877A can be programmed to allow the user to answer a page only if the digits 0, 2, or 3 are
entered in the wildcard access code.
If the PL1877A is operating in multi-mode paging, 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 entered in the wildcard
access prefix.
