System and method for remote testing and protocol analysis of communication lines
First Claim
1. A method of remote testing and analysis of a plurality of communication lines concentrated at a first location comprisingestablishing a first telephone communication between said first location and a facility distant from said first location;
- transmitting a command, issued at said facility, through said telephone communication to said first location;
performing nonintrusive protocol analysis of a selected line at said first location in response to receipt of said command;
automatically intitiating, at said first location, a second telephone communication with said facility; and
transmitting results of nonintrusive said protocol analysis by means of said second telephone communication to said facility.

Abstract
Protocol analysis circuitry is provided at a site at which a plurality of private line data circuits are interconnected with one or more trunk lines. The analysis circuitry is wired into each of the data circuits and trunk lines through appropriate jacks on a continuous long-term basis. A programmed personal computer is installed at the site for control of the analysis circuitry and selection of the circuit to be tested. Monitored data and analysis data can be stored in computer memory. Telephone access to the test site permits interaction between the site computer and a distant computer located, for example at a maintenance facility. Selection of the circuit to be tested and definition of network parameters to be measured can, therefore, be done remotely. The on site computer is provided with facsimile format capability so that stored data automatically can be communicated from the test site, through a telephone line, to a facsimile machine at the remote facility.

19. In a private line data network including a high speed trunk line connected to a host at a first location and connected to a plurality of data circuits by switching relays at a second location, a method for remote and unattended protocol analysis comprising the steps of:
-
transmitting a remote command to said second location; selecting a data circuit, in response to said remote command; nonintrusively supplying data corresponding to data transmitted on said high speed trunk line and said selected data circuit; performing protocol analysis of monitored data; storing supplied data and analysis data; and transmitting selected stored data to a designated external location. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
