scope:
This European Telecommunication Standard (ETS) specifies the electrical characteristics, the functional characteristics and the corresponding conformance tests for Terminal Equipment (TE) 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.
The requirements are intended to ensure correct reception and detection of the received data. The method of displaying the received data is not defined.
