Abstract
A communication system in which terminal equipments capable of both voice and data service are interconnectable through a full-duplex connection or leg rate-adapted in compliance with CCITT V.110 or in the like manner and arranged to be attached V.24 interfaces, and to a method for controlling the connection. To enable the use of terminal equipments for both voice and data service in conjunction with such a rate-adapted leg, adapters provided at both ends of the leg utilize V.24 status signal states in the leg for hand-shaking end-to-end signalling events between the terminal equipment.

A method for controlling a connection between terminal equipments in a communication system in which the connection includes at least one leg attached to V.24 interfaces and rate-adapted in compliance with the CCITT recommendation V.110 or an equivalent comprising:
- utilizing V.24 status signal states in said at least one leg for hand-shaking end-to-end signalling events between the terminal equipments which are significant to said at least one leg.
A communication system capable of establishing a connection between terminal equipments, comprising:
- at least one leg having two ends attached to V.24 interfaces and rate-adapter in compliance with the CCITT recommendation V.110 or an equivalent;
- adaptation means provided at both ends of said leg for adapting terminal equipment signals for said at least one leg, said connection adaptation means being structured for utilizing V.24 status signal states in said at least one leg for hand-shaking end-to-end signalling events between said terminal equipments which are significant to said at least one leg.
The communication system according to 12, wherein:
- one of said adaptation means comprises a terminal adapter means;
- and
- wherein a network termination means is associated with said terminal adapter means for providing rate-adaptation and signalling functions;
- a connection being set up between said terminal equipments via said terminal adapter means and network termination means such that said at least one leg is rate-adapted by said network termination means;
- said network termination means being structured for monitoring said V.24 status signal states in said at least one leg and effecting call control signalling, channel configuration or other automatic adaptation in response to at least one of said V.24 status signal states.
