6.13.8.1 Access / De-Access Codes
P25 conventional telephone calls use an access code to access the system when placing a
telephone call, and a de-access code to terminate the call when it is finished. These codes
are preprogrammed in pairs by the Access/De-Access Code list, and up to 16 pair can be
programmed. Each conventional P25 channel can be programmed to automatically select
one of these code pairs. They must match the system codes, and the default code is *1P#
(the P represents a pause).
