Abstract
Signal capture control circuitry for use integrated in a switch for a telecommunications network, includes circuitry for selecting at least one of the call paths corresponding to a given call, for signal capture for analysis. Capture control circuitry for controlling the signal capture on the selected call path and for communicating with the call control circuitry is also provided. Having the signal capture control as part of the switch, and communicating with call control circuitry of the switch, makes it becomes possible to analyse previously inaccessible signals in the switch or in its inputs or outputs. Also, it becomes possible to trigger signal capture based on call control events which do not appear externally.

Signal capture control apparatus for use integrated in a switch for a telecommunications network, the switch comprising a plurality of call paths, and call control circuitry for controlling a plurality of calls on the call paths through the switch, the apparatus comprising:
- selecting circuitry for selecting at least one of the call paths corresponding to a given one of the calls, for signal capture for analysis, and
- capture control circuitry for controlling the signal capture on the selected call path and for communicating with the call control circuitry.
A switch for a telecommunications network comprising:
- a plurality of call paths,
- call control circuitry for controlling a plurality of calls on the call paths through the switch, the apparatus comprising:
- selecting circuitry for selecting at least one of the call paths corresponding to a given one of the calls, for signal capture for analysis, and
- capture control circuitry for controlling the signal capture on the selected call path and for communicating with the call control circuitry.
A method of using signal capture apparatus in a switch for a telecommunication network, the switch comprising a plurality of call paths, and call control circuitry for controlling a plurality of calls on the call paths through the switch, the method comprising the steps of:
- selecting at least one of the call paths corresponding to a given one of the calls, for signal capture for analysis, and
- controlling the signal capture on the selected call path, the control involving communicating with the call control circuitry.
