5. Program the required values into the wildcard template.
For the example above, you have chosen Y 1 F Y F as the required wildcard structure. The last digit
of your wildcard structure must be programmed into parameter 535. Thus, you would program
parameters 530–535 as follows:
parameter 530: FF parameter 533: F
parameter 531: E parameter 534: E
parameter 532: 1 parameter 535: F
Notice that the Y digits (representing user ID digits) have been replaced by E (hexadecimal E). E is
referred to as the capcode wildcard digit since it is actually a special wildcard digit that is replaced
by capcode digits or the user ID digits.
To complete the example above, suppose the PL1877A has just paged the mobile corresponding to
user ID 56. The telephone user is waiting on a mobile answer since direct access is disabled. In this
situation, the PL1877A does not respond to any mobile access codes except those that match the
following structure: 51x6x* (where x represents wildcard digits — digits chosen by the mobile user
when transmitting the code).
Miscellaneous Information Regarding Wildcard Access/Release Feature
1. When the PL1877A is not paging a mobile, any capcode wildcards in the wildcard template are
treated as normal wildcard digits.
For example, suppose the PL1877A is programmed with the wildcard template E1FEF. Also, mobile
access has been restricted to users of multi-digit access prefixes, and all standard multi-digit access
prefixes have been disabled.
In this example, the mobile is always required to access the PL1877A with a wildcard prefix. To
answer a page, mobile users must substitute their user ID digits into the capcode wildcard positions.
However, to originate a call to a telephone user, the mobile treats the capcode wildcards as normal
wildcard digits.
That is, instead of substituting their user ID digits into the capcode wildcard positions, the mobile
can substitute any digits for those locations. Thus (continuing the example above), to answer a page,
the mobile must always use a wildcard access prefix that matches the pattern 51x6x. However, to
originate a call to a telephone user, the mobile may use a wildcard access prefix that matches the
pattern x1xxx.
2. If the wildcard template contains less capcode wildcards than there are digits in the capcode, only the
right-most digits of the capcode are used in the wildcard prefix. For example, suppose your wildcard
template contains E1FEF. Also, suppose your PL1877A is programmed for QuickCall II, single
mode selective signaling.
If the PL1877A pages a user with the capcode 023, the PL1877A requires wildcard access prefixes
that match the pattern 21x3x. Notice that only the right-most digits of the capcode were placed in the
wildcard prefix. Suppose your wildcard template contains E1234. Also, suppose your PL1877A is
programmed for multi-mode selective signaling. If the PL1877A pages user ID 56, the PL1877A
requires wildcard access prefixes that match the pattern 61234. Notice that only the right-most digit
of the user ID was placed in the wildcard prefix.
