scope:
This European Telecommunication Standard (ETS) specifies the electrical characteristics, the functional characteristics and the corresponding conformance tests for Terminal Equipment for connection to the network termination points of a Public Switched Telephone Network (PSTN) interface providing a Protocol over the local loop for display and related services based on the protocols defined in ETS 300 659-1 [1]. This ETS applies to the asynchronous voice-band Frequency Shift Keying (FSK) based subscriber line protocols. For those networks that implement a Dual Tone Multi Frequency (DTMF) based subscriber line protocol, network specific (TE) requirements apply (see annex A).
This ETS applies to off-line data transmission only.
This ETS is not written for regulatory purposes.
The requirements are intended to ensure correct reception and detection of the received data. The method of displaying the received data is not defined.
