[Bit 1]
When the incoming call is rejected, sending of the RELCOMP message can be set to either
Yes or No. If “
No ” is selected, the RELCOMP message will not be sent if an incoming call
is rejected because transmission is in progress, etc.; no response is sent. If “ Yes ” is selected,
the RELCOMP message will be sent when the incoming call is rejected. However, in cases
where transmission is rejected because results of the incoming address check do not agree,
the RELCOMP message will not be sent even if “
Yes ” is selected.
[Bit 2]
For outgoing G4 calls, it is possible to choose whether to automatically fallback to G3 in
cases where an error occurs in the D-channel connection procedure. If “
Yes ” is selected, the
machine will fallback to G3 and call again after releasing the call if notification of a “cause
number” corresponding to the error code set under the
#4C ISDN menu in ISDN BASIC
G4/G3 Fallback is received from the network after a G4 call is made.
[Bit 3]
For outgoing 3.1kHz audio calls, it is possible to choose whether to automatically fallback
to speech in cases where an error occurs in the D-channel connection procedure. If “
Yes ” is
selected, the machine will fallback to speech and call again after releasing the call if
notification of a “cause number” corresponding to the error code set under the
#4C ISDN
menu in ISDN BASIC Speech Fallback is received from the network after a 3.1kHz-
audio call is made.
