Abstract
An apparatus for use in an all digital loop contains a first network node ( ), a second network node ( ), and a data transmission line ( ) there between. Each one of the first and second network nodes ( ) is operable to transmit to the other at least one digitised telephone signal with other digital data via a set of carriers. One of the first and second network nodes ( ) thereto includes or is associated with means which in the event of power failure at the first network node ( ), is operable selectively to provide power to the first node ( ) such that the first node ( ) operates only via a limited subset of said carriers. This limited subset is such as to minimise the power required for the transmission of a telephone lifeline signal between the first and second nodes ( ).
