scope:
This European Telecommunications Standard (ETS) defines Terminal Adaptation Functions (TAF) which are integrated in a Mobile Termination (MT) and which enable the attachment of Synchronous Terminals to an MT (see GSM 04.02 [4]). The general aspects of Terminal Adaptation Functions are contained in specification GSM 07.01 (ETS 300 913) [8]. This ETS covers support of synchronous data services (see GSM 02.02 (ETS 300 904)[2]) for the following interfaces and procedures:
- V.22 DTE/DCE Interface
- V.22 bis DTE/DCE Interface
- V.26 ter DTE/DCE Interface
- V.32 DTE/DCE Interface
- X.21 DTE/DCE Interface
- X.21 bis DTE/DCE Interface
- X.25 Procedure
- X.32 Procedure
- V.25 bis Procedure
- I.420 Interface (S)
LAPB is the only synchronous non-transparent protocol which is considered here.
