Abstract
An improved telemetry system in which suppressed ringing connections are established through a switching network to access equipment at subscriber locations. The control equipment for controlling the switching network is specifically adapted to include a set-up routine for identifying the signalling modes for the loop networks connected to the subscriber locations. The control equipment additionally is adapted to permit access by a user of the telemetry system to a subscriber location by first using a no signal signalling mode and, if unsuccessful, an identified signalling mode for the subscriber location. Finally, the control equipment is also adapted to automatically generate telemetry system information for each subscriber location from telephone system and user customer information so that the telemetry system and user customer information are linked by a common reference ID associated with the equipment at a subscriber location.
