Abstract:
1. An apparatus for interfacing with analog subscriber loops of a telephony communication system and for obtaining, from at least one of said analog subscriber loops, digital test data that may be used to test said telephony communication system, comprising: a digital-to-analog (D/A) converter configured to receive digital data and to convert said digital data into a first analog signal; a first port of the apparatus configured to interface with a first analog subscriber loop, said first port configured to transmit said first analog signal across said first analog subscriber loop; a second port of the apparatus configured to interface with a second analog subscriber loop which is a different analog subscriber loop than the first analog subscriber loop, said second port configured to receive a second analog signal from said second analog subscriber loop; and an analog-to-digital (A/D) converter configured to receive said second analog signal and to convert said second analog signal into said digital test data, wherein said first analog signal is transmitted across said first analog subscriber loop to a telephony communication network that translates said first analog signal into said second analog signal and that transmits said second analog signal to said second port via said second analog subscriber loop, thereby establishing a communication session between the first port and the second port of the apparatus for testing a communication path from the first port to the second port.
