Abstract
A system for managing access by a plurality of terminal devices to an access line of a public switched telephone network (PSTN). The system comprises a SAU (service access unit) connected to the access line, and a FSP (full service provider) which is interconnectable through a call connection within the telephone network to the SAU. The SAU includes a plurality of interfaces each adapted to communicate with a respective terminal device connected thereto. This combination of the SAU and the FSP interconnected through the PSTN enables each of the terminal devices to access or be accessed from multiple service networks. The management system effectively provides multiple independent telephony "service" over the single access line by sharing the available bandwidth of the PSTN connection between the SAU and the FSP amongst the various terminal devices as required.
