+FAA Adaptive answer
A Service Class 1 Facsimile DCE may have the ability to answer as a data modem DCE or as a Facsimile DCE. It
also may be able to adaptively change from Class 1 facsimile mode (•FCLASS•1.0) to data modem operation
(•FCLASS•0) in response to the incoming call. The •FAA parameter controls this feature.
– Write syntax: •FAA•<value>
– Valid values: 0, 1
– Default value: 0
– Mandatory value: 0
•FAA•0 The DCE shall answer only as a Class 1 facsimile device. No automatic switching of service class
shall occur based on the calling device type.
•FAA•1 The DCE can answer and automatically determine whether to answer as a facsimile DCE or as a
data modem. If a data modem is detected, the DCE shall operate as described in 8.3.2.4.
NOTE – The •FAA parameter controls automatic switching only from Class 1 to Class 0, for call answering only. It
does not affect call origination, switching to Class 1 from other classes, or switching to classes other than Class 0.
