This TS defines Terminal Adaptation Functions (TAF) which are integrated in a Mobile Termination
(MT) and which enable the use of synchronous bearer services in the PLMN and the attachment of Synchronous
synchronous Terminals terminals to an MT (see TS 24.002
For the case where asynchronous terminals are attached to the TAF when using synchronous bearer services in the PLMN, the reader is referred to TS 27.002
for the asynchronous MT-TAF interface specifics and to the present document for synchronous bearer service
specifics on the TAF-IWF interface.
The general aspects of Terminal Adaptation Functions are contained in
specification TS 27.001
. The present document covers support of synchronous data services (see TS 22.002
for the following interfaces and procedures:
V.22 DTE/DCE Interface;
V.22 bis DTE/DCE Interface;
V.26 ter DTE/DCE Interface;
X.21 bis DTE/DCE Interface;
V.25 bis Procedure.
