7. 4 User-to-user signalling (UUS)
The service "user-to-user signalling" allows users to exchange a limited volume of data
(128 bytes per user) among themselves over the signalling channel (D channel) during

even if a call is not answered.
Requirements:
• Both users must have subscribed to the service with the network provider.
