It may not be desirable to override all of the restrictions in listed in the table. You can program the
PL1877A to override some of the restrictions, however, this limits the number of restrictions that can be
overridden by a single multi-digit access prefix. For example, suppose you require that the security code
cannot override the manual dialing restriction (restriction #4). Doing this results in none of the multi-
digit access prefixes being capable of overriding the manual dialing restriction.
N
OTE
: As a general rule, a multi-digit access prefix can only override restrictions that can be overridden
by the security code.

Limiting Interconnect Access to Users of Multi-Digit Prefixes
The PL1877A can be programmed to allow access to the phone line only if the mobile user enters a
multi-digit access sequence. This feature can be used to prevent the PL1877A from responding to the
basic access commands: *, *#, ** and *n.
