Post Connect Dialing Options
Determines whether additional capabilities, beyond standard ISDN dialing, are available for
those incoming ISDN trunk calls that are mapped into XMOBILE stations. These options come
into effect after the call has entered the active state (Communication Manager has sent a
CONNECT message back to the network).

Usage
Expect digits from either in-band or out-of-band, but not simultaneously.
The server allocates a DTMF receiver whenever it needs to collect digits.
This option normally would be used for Extension to Cellular XMOBILE
station calls.
Expect all digits to be delivered by out-of-band signaling only. The server
running Avaya Communication Manager collects digits that it needs from
the out-of-band channel (no touch-tone receiver). In addition, any digits
received when the server is not collecting digits are converted to DTMF
and broadcast to all parties on the call. This option is in force for DECT
XMOBILE station calls.
Expect all subsequent digits to be delivered by simultaneous in-band and
out-of-band signaling. Out-of-band signaling consists of digits embedded
in ISDN INFO messages while the in-band signaling consists of DTMF in
the voice path. The server running Communication Manager collects all
digits that it needs from the out-of-band channel. No touch tone receive is
allocated in order to prevent collecting double digits. End-to-end signaling
occurs transparently to the server via in-band transmission of DTMF. This
option is in force for PHS XMOBILE station calls.
