Patent ID: 7356127

Claim:
A telephony testing system comprising: a digital measurement unit (DMU) operative for outputting a subscriber's telephone number, POTS test signals and wideband test control signals; digital communication network (DCN) including a remote terminal (RT); means for converting the subscriber's telephone number to a subscriber's telephone number signal, for outputting the subscriber's telephone number signal to the DCN and for routing the POTS test signals to the DCN; and a digital wideband node (DWN) coupled to the RT, wherein: the DCN conveys the subscriber's telephone number signal, the POTS test signals and the wideband test control signals to the DWN; the DWN routes the subscriber's telephone number signal received via the DCN to the RT whereupon the RT couples a corresponding subscriber's telephone line to the DWN via a test path; the DWN routes POTS test signals received via the DCN to the subscriber's telephone line via the test path; and the DWN converts the wideband test control signals received via the DCN into wideband test signals which are conveyed to the subscriber's telephone line via the test path.
