Abstract
Abstract A system is tested by providing a canned speed signal (a signal containing known speech) from a diagnostic controller to an encoder of the communication system. The canned signal is encoded forming an encoded canned speech signal. The encoded signal is transmitted to an where it is then decoded. The decoded signal is compared with the original canned speech signal in the diagnostic controller. A report of the comparison is then provided to a maintenance facility.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
A method for testing a communication system comprising the steps of: providing a canned speed signal from a diagnostic controller to an encoder of said communication system; encoding said canned speed signal in said encoder, forming an encoded canned speed signal; transmitting said encoded caned speed signal to a transmitter of said communication system; transmitting said encoded canned speech signal from said transmitter to a subscriber unit; transmitting said encoded canned speech signal from said subscriber unit to a receiver of said communication system; transmitting said encoded canned speech signal from said receiver to a decoder of said communication system; decoding said encoded canned speech signal in said decoder forming a decoded canned speech signal; comparing said decoded canned speech signal with said canned speech signal from said diagnostic controller; and reporting a result of said comparing step.
Claim 2
Independent Claim
138 words
A method for testing a communication system comprising the steps of: providing a canned speed signal from a diagnostic controller to an encoder of said communication system; encoding said canned speed signal in said encoder, forming an encoded canned speed signal; transmitting said encoded caned speed signal to a transmitter of said communication system; transmitting said encoded canned speech signal from said transmitter to a subscriber unit; transmitting said encoded canned speech signal from said subscriber unit to a receiver of said communication system; transmitting said encoded canned speech signal from said receiver to a decoder of said communication system; decoding said encoded canned speech signal in said decoder forming a decoded canned speech signal; comparing said decoded canned speech signal with said canned speech signal from said diagnostic controller; and reporting a result of said comparing step.
Claim 3
Dependent Claim
32 words
The method of claim 1 further comprising the step of processing said canned speech signal through a first forward error correction circuit of said communication system between said encoder and said transmitter.
Claim 4
Dependent Claim
32 words
The method of claim 1 further comprising the step of processing said canned speech signal through a second forward error correction circuit of said communication system between said receiver and said decoder.
Claim 5
Dependent Claim
21 words
The method of claim 1 wherein said step of reporting comprises the step of reporting an audio report to a user.
Claim 6
Dependent Claim
21 words
The method of claim 1 wherein said step of reporting comprises the step of reporting a visual report to a user.
Claim 7
Independent Claim
200 words
A method for testing a communication system comprising the steps of: providing a canned speech signal from a diagnostic controller to an encoder of said communication system; encoding said canned speech signal in said encoder, forming an encoded canned speech signal; transmitting said encoded canned speech signal to a first forward error correction circuit of said communication system where said encoded canned speech signal is forward error correction encoded, forming an FEC encoded signal; transmitting said FEC encoded signal from said first forward error correction circuit to a transmitter of said communication system; transmitting said FEC encoded signal from said transmitter to a subscriber unit; transmitting said FEC encoded signal from said subscriber unit to a receiver of said communication system; transmitting said FEC encoded signal from said receiver to a second forward error correction circuit where said FEC encoded signal is decoded forming an FEC decoded signal; transmitting said FEC decoded signal from said second forward error correction circuit to said decoder; decoding said FEC decoded signal in said decoder forming a decoded canned speech signal; comparing said decoded canned speech signal with said canned speech signal from said diagnostic controller; and reporting a result of said comparing step.
Claim 8
Independent Claim
200 words
A method for testing a communication system comprising the steps of: providing a canned speech signal from a diagnostic controller to an encoder of said communication system; encoding said canned speech signal in said encoder, forming an encoded canned speech signal; transmitting said encoded canned speech signal to a first forward error correction circuit of said communication system where said encoded canned speech signal is forward error correction encoded, forming an FEC encoded signal; transmitting said FEC encoded signal from said first forward error correction circuit to a transmitter of said communication system; transmitting said FEC encoded signal from said transmitter to a subscriber unit; transmitting said FEC encoded signal from said subscriber unit to a receiver of said communication system; transmitting said FEC encoded signal from said receiver to a second forward error correction circuit where said FEC encoded signal is decoded forming an FEC decoded signal; transmitting said FEC decoded signal from said second forward error correction circuit to said decoder; decoding said FEC decoded signal in said decoder forming a decoded canned speech signal; comparing said decoded canned speech signal with said canned speech signal from said diagnostic controller; and reporting a result of said comparing step.
Claim 9
Dependent Claim
21 words
The method of claim 6 wherein said step of reporting comprises the step of reporting an audio report to a user.
Claim 10
Dependent Claim
21 words
The method of claim 6 wherein said step of reporting comprises the step of reporting a visual report to a user.
Claim 11
Independent Claim
132 words
A method for testing a communication system comprising the steps of: providing a canned speech signal from a diagnostic controller to an encoder of said communication system; encoding said canned speech signal in said encoder, forming an encoded canned speech signal; transmitting said encoded canned speech signal to a first forward error correction circuit; transmitting said encoded canned speech signal from said first forward error correction circuit to a second forward error correction circuit; transmitting said encoded canned speech signal from said second forward error correction circuit to a decoder of said communication system; decoding said encoded canned speech signal in said decoder forming a decoded canned speech signal; comparing said decoded canned speech signal with said canned speech signal from said diagnostic controller; and reporting a result of said comparing step.
Claim 12
Independent Claim
132 words
A method for testing a communication system comprising the steps of: providing a canned speech signal from a diagnostic controller to an encoder of said communication system; encoding said canned speech signal in said encoder, forming an encoded canned speech signal; transmitting said encoded canned speech signal to a first forward error correction circuit; transmitting said encoded canned speech signal from said first forward error correction circuit to a second forward error correction circuit; transmitting said encoded canned speech signal from said second forward error correction circuit to a decoder of said communication system; decoding said encoded canned speech signal in said decoder forming a decoded canned speech signal; comparing said decoded canned speech signal with said canned speech signal from said diagnostic controller; and reporting a result of said comparing step.
