PAD service signals
The PAD acknowledges commands and informs the user about the internal state of the PAD by
transmitting PAD service signals to the terminal server. The terminal-server user can suppress
the reception of PAD service signals by setting PAD parameter #6 to 0. Table 6-4 lists the PAD
service signals.

MAX 6000/3000 Network Configuration Guide
The Listen command specifies the match pattern for accepting an incoming call. It uses
the following syntax:
–
The MAX matches the address argument against the subaddress specified by the
incoming call. If the subaddresses match, the MAX accepts the incoming call.
–
The MAX matches the data against the last 12 bytes of the user data field of
incoming calls. If the data matches, the MAX accepts the incoming call.
