Full Description

This Technical Specification (TS) defines the interfaces and Terminal Adaptation Functions (TAF) integral to a Mobile Termination (MT) which enables the attachment of asynchronous terminals to a MT (see GSM 04.02 [4]). The general aspects of Terminal Adaptation Functions are contained in GSM 07.01 [7]. This TS covers support of these services for the following interfaces and procedures: (i)V.14 procedures (ii)V.21 DTE/DCE interface (iii)V.22bis DTE/DCE interface (iv)V.23 DTE/DCE interface (v)V.32 DTE/DCE procedures (vi)I.420 S interface (vii)V.25bis signalling procedures (viii)V.25ter signalling procedures The asynchronous data rates between the MT and the TE2 are defined in GSM 02.02 [2].
