the analog Tip and Ring leads of any FXO port. It also sets and monitors the state of the digitized voice signal’s ABCD signaling bits in cross-connect systems, the Test functionality also includes the ability to generate test tones (300Hz, 1 kHz, 3 kHz and “quiet”) and transmit those toward either the user side or the network side of the system. Table 11 reviews the FXO Card

specifications.
