This TS defines the interfaces and Terminal Adaptation Functions (TAF) integral to a Mobile
Termination (MT) which enable the use of asynchronous bearer services in the PLMN and the attachment of
asynchronous terminals to a MT (see TS 24.002
and TS 23.101
The general aspects of Terminal Adaptation Functions are contained in TS 27.001
The present document covers support of these services for the following interfaces and procedures:
ITU-T V.14 procedures.
ITU-T V.21 DTE/DCE interface.
ITU-T V.22bis DTE/DCE interface.
ITU-T V.32 DTE/DCE procedures.
ITU-T I.420 S interface.
ITU-T V.250 signalling procedures.
The asynchronous data rates between the MT and the IWF are defined in TS 22.002
