d) Information elements in the SETUP message
The SETUP message is one of the messages used in the D-channel Layer 3 communication
protocol, as opposed to a network, and requires commencement of call settings. It is listed
here, in the information element included in the main message, as a necessary element for
the machine’s service.
Sending Complete
Gives notification of completion of the Called Party Number destination. Addition of this
required information is handled as an option in ITU-T recommendations. Additionally, the
required information can be set as “Add/Do not Add” with a service switch on this
machine.
Bearer Capability
Sets an outgoing G4 call to “unrestricted digital”, an outgoing G3 call to “3.1kHz audio”,
and telephone to “speech”. (There is no telephone in this machine.) It must be ensured that
the information in question is added according to ITU-T recommendations.
Channel Identification
Designates the B-channel which will be used from now on. “B1 channel”, “B2 channel”,
“any channel”, and “no channel” will all be set. It must be ensured that the information in
question is added according to ITU-T recommendations.
Progress Indicator
Notifies the channel generated for the call. Addition of this required information is handled
as an option in ITU-T recommendations. Additionally, using a service switch, the progress
contents can be set, and the required Progress Indicator information can be set as “Add/Do
not Add” on this machine.
Calling Party Number
Sets the phone number of the calling party (=the machine itself). Addition of this required
information is handled as an option in ITU-T recommendations.
Called Party Number
Sets the telephone number of the called party. Addition of this required information is
handled as an option in ITU-T recommendations.
Low Layer Compatibility
Sets an outgoing G4 call to “unrestricted digital”, an outgoing G3 call to “3.1kHz audio”,
and telephone to “speech”. (There is no telephone in this machine.) Addition of this
required information is handled as an option in ITU-T recommendations. Additionally, this
machine can use a service switch to set the required information to “Add/Do not Add” in
the SETUP message when calling with G4/G3.
