scope:
The present document specifies the electrical characteristics and the functional characteristics 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 EN 300 659-1 [1] and EN 300 659-3 [3]. For those networks that have implemented a Dual Tone Multi Frequency (DTMF) based subscriber line protocol, network specific TE requirements apply (see annex A).
The present document applies to on-hook 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.
