Telecommunications test system including a test and trouble shooting expert system

A telecommunication test system for a subscriber line of a telephone network to be tested comprising:

• a test measurement device arranged to coupled to said subscriber line, and being operative to derive a plurality of respectively different parameter measurement data from said subscriber line;
• a portable communication and processing unit, through the operation of which testing of said subscriber line may be conducted by means of a test system of a telephone facility, said test system being operative to respond to signals supplied thereto over a communication path from said portable communication and processing unit and to supply messages to said portable communication and processing unit for providing information for controlling the operation of said test measurement device, said portable communication and processing unit having the capability of conducting communications through a wireless communication path to said test measurement device;
• and
• a mobile communication and signal processing facility, separate from said portable communication and processing unit and said telephone facility, through which a first auxiliary wireless communication path may be established with said portable communication and processing unit, and through which a second auxiliary wireless communication path may be established with said telephone facility.

A telecommunication test system for a communication line to be tested, comprising:

• a test measurement device which is configured to be coupled with said communication line, said test measurement device deriving a plurality of respectively different parameter measurement data from said communication line;
• a processor which receives and processes said respectively different parameter measurement data;
• at least one communication path provided between said test measurement device and said processor for conveying said plurality of respectively different parameter measurement data from said test measurement device to said processor, said at least one communication path including a wireless communication path;
• and
• a central office for placing various test signals on said communication line being tested;
• and wherein
• said at least one communication path includes a further wireless communication path between said processor and said central office.

A telecommunication test system for a line to be tested, comprising:

• a test measurement device coupled with said line, and being operative to derive a plurality of respectively different parameter measurement data from said line;
• a processor which receives and processes said parameter measurement data from said test measurement device;
• a first, wireless communication path, coupled between said test measurement device and said processor, for transmitting said plurality of respectively different parameter measurement data from said test measurement device to said processor;
• a central office and a data test center for placing various signals on said line;
• and
• a mobile facility coupled in communication with said processor by way of a primary wireless path and a back-up wireline path, and also coupled in communication with at least one of said central office and said data test center by way of a further primary wireless path and a further back-up wireline path.
