Abstract
Abstract Whether or not the provisioning of a given BRI is properly administered is determined by providing a collection of processes which exercise the known network provided supplementary services in a predetermined fashion. Specifically, a predetermined, i.e., algorithmic, process is employed to examine an administration database to determine which DSLs are to support supplementary services and, then, the process invokes a plurality of processes which attempt to activate the expected supplementary service. The basic mode of operation is to generate a connectivity context in which the supplementary service can be invoked and, then, cause the service to be invoked. ISDN messages are transmitted to the network over the D channel of the given BRI both to establish the service context and, then, to invoke the supplemental service. By analyzing the processes and ISDN messages the system can determine if the desired supplementary services are available, and the results of the analysis are recorded and made available to an operator.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
100 words
Premises switching apparatus for use in testing if a supplementary service has been correctly administered on a given subscriber line comprising: means for generating call control messages for the service being tested; means for transmitting the generated call control messages to a connecting switch; said call control messages causing initiation of call state transitions; and analysis means for comparing call state transitions initiated by the transmitted call control messages to predetermined nominal call state transitions for the supplementary service being tested to determine if the supplementary service has been correctly administered by the connecting switch for the given subscriber line.
Claim 2
Dependent Claim
100 words
Premises switching apparatus for use in testing if a supplementary service has been correctly administered on a given subscriber line comprising: means for generating call control messages for the service being tested; means for transmitting the generated call control messages to a connecting switch; said call control messages causing initiation of call state transitions; and analysis means for comparing call state transitions initiated by the transmitted call control messages to predetermined nominal call state transitions for the supplementary service being tested to determine if the supplementary service has been correctly administered by the connecting switch for the given subscriber line.
Claim 3
Dependent Claim
33 words
Premises switching apparatus as defined in claim 1 wherein said test of the connecting switch administration is done on a directory number basis, said directory number identifying at least one emulated station terminal.
Claim 4
Dependent Claim
33 words
Premises switching apparatus as defined in claim 1 further including means for storing and for algorithmically selecting the supplementary service test routines, and means for analyzing the results achieved against expected nominal performance.
Claim 5
Dependent Claim
19 words
Premises switching apparatus as defined in claim 1 further including means for reporting results of said supplementary service test.
Claim 6
Dependent Claim
17 words
Premises switching apparatus as defined in claim 4 further including means for terminating the supplementary service test.
Claim 7
Dependent Claim
28 words
The invention as defined in claim 1 wherein said customer premises switching apparatus further includes means for testing to determine whether prescribed basic services have been properly administered.
Claim 8
Independent Claim
101 words
A method for use in premises switching apparatus for testing if a supplementary service has been correctly administered on a given subscriber line comprising the steps of: generating call control messages for the service being tested; transmitting the generated call control messages to a connecting switch; said call control messages causing initiation of call state transitions; and analyzing call state transitions initiated by the transmitted call control messages as compared to predetermined nominal call state transitions for the supplementary service being tested to determine if the supplementary service has been correctly administered by the connecting switch for the given subscriber line.
Claim 9
Independent Claim
101 words
A method for use in premises switching apparatus for testing if a supplementary service has been correctly administered on a given subscriber line comprising the steps of: generating call control messages for the service being tested; transmitting the generated call control messages to a connecting switch; said call control messages causing initiation of call state transitions; and analyzing call state transitions initiated by the transmitted call control messages as compared to predetermined nominal call state transitions for the supplementary service being tested to determine if the supplementary service has been correctly administered by the connecting switch for the given subscriber line.
Claim 10
Dependent Claim
32 words
The method as defined in claim 7 wherein said test of the connecting switch administration is done on a directory number basis, said directory number identifying at least one emulated station terminal.
Claim 11
Dependent Claim
30 words
The method as defined in claim 7 further including the steps of storing and algorithmically selecting the supplementary service test routines, and analyzing the results achieved against expected nominal performance.
Claim 12
Dependent Claim
19 words
The method as defined in claim 7 further including the step of reporting results of said supplementary service test.
Claim 13
Dependent Claim
17 words
The method as defined in claim 10 further including the step of terminating the supplementary service test.
Claim 14
Dependent Claim
23 words
The method as defined in claim 7 further including the step of testing to determine whether prescribed basic services have been properly administered.
Claim 15
Dependent Claim
102 words
Premises switching apparatus for use in testing if a supplementary service has been correctly administered on a given subscriber line comprising: a generator for generating call control messages for the service being tested; a transmitter for transmitting the generated call control messages to a connecting switch; said call control messages causing initiation of call state transitions; and a comparator for comparing call state transitions initiated by the transmitted call control messages to predetermined nominal call state transitions for the supplementary service being tested to determine if the supplementary service has correctly been administered by the connecting switch for the given subscriber line.
Claim 16
Dependent Claim
102 words
Premises switching apparatus for use in testing if a supplementary service has been correctly administered on a given subscriber line comprising: a generator for generating call control messages for the service being tested; a transmitter for transmitting the generated call control messages to a connecting switch; said call control messages causing initiation of call state transitions; and a comparator for comparing call state transitions initiated by the transmitted call control messages to predetermined nominal call state transitions for the supplementary service being tested to determine if the supplementary service has correctly been administered by the connecting switch for the given subscriber line.
Claim 17
Dependent Claim
33 words
Premises switching apparatus as defined in claim 13 wherein said test of the connecting switch administration is done on a directory number basis, said directory number identifying at least one emulated station terminal.
Claim 18
Dependent Claim
40 words
Premises switching apparatus as defined in claim 13 further including a storage element for storing and a control element for algorithmically selecting the supplementary service test routines, and an analysis element for comparing the results achieved against expected nominal performance.
Claim 19
Dependent Claim
19 words
Premises switching apparatus as defined in claim 13 further including apparatus for reporting results of said supplementary service test.
Claim 20
Dependent Claim
17 words
Premises switching apparatus as defined in claim 16 further including apparatus for terminating the supplementary service test.
Claim 21
Dependent Claim
28 words
The invention as defined in claim 13 wherein said customer premises switching apparatus further includes apparatus for testing to determine whether prescribed basic services have been properly administered.
