    Abstract - (Show below) - (Hide below)

    States technical requirements under Section 22 of the telecommunications Act 1984 for terminal equipment for connection to analogue interfaces of public networks run by certain public telecommunications operators providing: a 2-wire presentation without capacitive termination, either earth calling, loop call- disconnect clearing, loop calling-guarded clearing or loop calling-unguarded clearing signalling methods, loop disconnect pulsing and multifrequency (MF) tone call routeing signalling, where the terminal equipment is either self or line powered.
