Telemetry system with suppressed ringing connection
First Claim
1. A telemetry system for accessing equipment at telephone subscriber locations over telephone loop networks which require different signalling modes for initiating operation, said equipment at each subscriber location generating an acknowledgement signal when accessed, and said system comprising:
- a telephone switching network for providing access to said subscriber locations over said telephone loop networks serving said subscriber locations;
and first means for controlling said telephone switching network so as to establish suppressed ringing connections through said telephone switching network to said subscriber locations over said telephone loop networks for accessing said equipment, said first means including a set-up routine for identifying the signalling mode of the telephone loop network serving a subscriber location by;
controlling said telephone switching network to sequentially attempt to establish a suppressed ringing connection through said telephone switching network to the subscriber location over the telephone loop network serving the subscriber location using a different one of said signalling modes during each said attempt;
after each said attempt waiting for an acknowledgement from the equipment at the subscriber location before proceeding with a next attempt; and
after an acknowledgement is received, ceasing any subsequent attempts and identifying the telephone loop network serving the subscriber location with the signalling mode which resulted in said acknowledgement.

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.

16. A telemetry system for accessing equipment at telephone subscriber locations over telephone loop networks which require different signalling modes for initiating operation, said different signalling modes including a first signalling mode and at least one second signalling mode and each subscriber location having a signalling mode currently identified with the telephone loop network serving the subscriber location, said system comprising:
-
a telephone switching network for providing access to said subscriber locations over said telephone loop networks serving said subscriber locations; and first means for controlling said telephone switching network so as to establish a suppressed ringing connection through said telephone switching network over a particular telephone loop network serving a particular subscriber location for accessing the particular subscriber location, said first means having an access routine including;
first attempting to establish said suppressed ringing connection through said telephone switching network using said first signalling mode; and
, if said first attempt to establish said suppressed ringing connection fails, further attempting to establish said suppressed ringing connection using the signalling mode currently identified with the particular telephone loop network serving the particular subscriber location. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A telemetry system for use in accessing equipment at subscriber locations for which said telemetry system contains telephone system information related to said subscriber locations, said subscriber locations defining customers of a user of the telemetry system which user is to access said equipment through said telemetry system, said user having user customer information related to said subscriber locations, the telephone system comprising:
-
a telephone switching network for providing communication to said subscriber locations through said telephone switching network; and first means for controlling said telephone switching network to provide a suppressed ringing connection to a particular subscriber location through said telephone switching network, said first means including a telemetry system information generation routine which automatically generates for a subscriber location telemetry system information containing certain of the customer user information and certain of the telephone system information related to the particular subscriber location. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)

31. A method for accessing equipment at telephone subscriber locations over telephone loop networks which require different signalling modes for initiating operation, said equipment at each subscriber location generating an acknowledgement signal when accessed, and said method comprising:
-
accessing said subscriber locations over said telephone loop networks serving said subscriber locations through a telephone switching network; and controlling said telephone switching network so as to establish suppressed ringing connections through said telephone switching network to said subscriber locations over said telephone loop networks for accessing said equipment, said controlling including using a set-up routine for identifying the signalling mode of the telephone loop network serving a subscriber location by;
controlling said telephone switching network to sequentially attempt to establish a suppressed ringing connection through said telephone switching network to the subscriber location over the telephone loop network serving the subscriber location using a different one of said signalling modes during each said attempt;
after each said attempt waiting for an acknowledgement from the equipment at the subscriber location before proceeding with a next attempt; and
after an acknowledgement is received, ceasing any subsequent attempts and identifying the telephone loop network serving the subscriber location with the signalling mode which resulted in said acknowledgement. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

A method for accessing equipment at telephone subscriber locations over telephone loop networks which require different signalling modes for initiating operation, said different signalling modes including a first signalling mode and at least one second signalling mode and each subscriber location having a signalling mode currently identified with the telephone loop network serving the subscriber location, said method comprising:
-
accessing said subscriber locations over said telephone loop networks serving said subscriber locations through a telephone switching network; and controlling said telephone switching network so as to establish a suppressed ringing connection through said telephone switching network over a particular telephone loop network serving a particular subscriber location for accessing the particular subscriber location, said controlling including using an access routine comprising;
