071: Configure a Link for Preaccess

This command sets up a link to use the preaccess system. Links that are configured for preaccess

will ignore any DTMF tones that are not preceeded by Z..Z where Z..Z is the site access code you

specify below. This allows commands to be sent down a linking system without every controller

along the way trying to execute them, sending error messages, etc. To execute a command from

such a link port, key up, enter Z..Z and the command. It will be executed when you unkey or press

'D'

<071> p y z..z

Parameters:

- 071 is the default command name.

- P is the port to set up as a preaccess link

- Y is 0 for no dial tone when accessed, 1 for dial tone

- Z..Z is the site access code. Typical site access codes are "#11", "#75", "#99", etc., that is

a '#' followed by two decimal digits. The controller will allow any preaccess

code from 1 to 6 digits long with any of the 16 DTMF digits in it, although

you may have to change your force-execution digit temporarily (see

command 078) while you execute this command to use the force-execution

digit as part of the access code.
