[Bit1]
When the incoming call is impossible because transmission is in progress, sending of the RELCOMP
message can be set to either "Yes" or "No."
[Bit2]
For outgoing G4 calls, automatic fallback from G4 to G3 can be set to either "Yes" or "No". In an
outgoing G4 call where this bit is set to "0," if the network gives notification of a "cause number" which
corresponds to an error code set in #4B ISDN BASIC G4/G3 Fallback, an outgoing G3 call will be
made after the machine makes one open call.
[Bit3]
For outgoing G3 calls, automatic fallback from "3.1kHz audio" to "Speech" can be set to either "Yes"
or "No". In this machine, with a regular outgoing G3 call, the Bearer Capability information element in
the SETUP message is set to "3.1kHz audio". In an outgoing G3 call where this bit is set to "0," if the
network gives notification of a "cause number" which corresponds to an error code set in #4B ISDN
BASIC Speech Fallback after the machine makes one open call, the Bearer Capability information
element in the SETUP message is set to "Speech," and an outgoing G3 call is made.
