1 Scope
This standard specifies the technical characteristics (electrical, logical and acoustic) for terminal equipment
for the 3,1 kHz telephony teleservice which can be connected to an ISDN basic access.
The requirements of this standard are additional to those of the standards for connection to the ISDN basic
access, and of any other standards to which the terminal equipment is subject.
This standard is applicable to simple telephony terminals as well as to the telephony
