Communication system and a method for controlling a connection in the communication system
First Claim
1. 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.

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.
