Result
FAIL The reflective looparound test failed. This could cause noisy or unreliable
connections, or users calling this port may hear an echo. The problem
can also be off-board.
1. Since a line seizure may affect the test, repeat the test at 1-minute
intervals up to 5 times.
2. Enter test board location to run circuit pack tests to check the
Tone Generator and the Tone Detector circuits on the IPSIs or the
Tone Generator/Tone Detector circuit packs.
3. Resolve any problems on the Tone Generator or the Tone Detector
circuit.
4. If the Tone Generator and Tone Detector circuits are functioning
properly, determine whether a voice terminal is connected and wired
properly. Resolve any problems found.
5. If the test still fails, replace the analog line circuit pack.
PASS The port provides an analog transmission path to the station equipment.
Investigate user-reported troubles on this port by running other port tests,
by examining station wiring, or by inspecting the station.

Speech Synthesis DTMF Receiver Test (#163)
A series of dual-tone multifrequency (DTMF) tones are conferenced from the TDM bus into the
port’s DTMF receiver and checked to see if the correct tones have been detected during the
correct intervals. If every DTMF tone was detected correctly, the test passes. If any of the tones
were not detected correctly, the test fails.
