1 Scope
This European Telecommunication Standard (ETS) specifies the requirements for a terminal to interwork
with the circuit-mode 64 kbit/s 8 kHz structured bearer service with a category usable for Speech
information transfer when connected by the pan-European Integrated Services Digital Network (ISDN).
The requirements of this ETS are additional to those of the ETSs for connection to the ISDN basic access
interface or primary rate interface.
Annex A to this ETS specifies the method of testing required to identify conformance to this ETS as
defined in ETS 300 109 [4].
NOTE : The characteristics of the ISDN User-Network Interface are specified in ETS 300 012
and ETS 300 104 [3] and the attachment requirements are specified in ETS 300 153
[5] (see Clause 2).
