The paper describes the special equipment developed to meet the high-grade requirements of this service. The C.C.I. requirements have been met in designing the equipment with respect to frequency range and attenuation distortion, delay distortion and circuit attenuation.

The arrangements for switching a programme from one line to another are fully dealt with.
