140AY loop around test (#210)
This test checks the integrity of the record channel on the Announcement circuit pack
(Announcement Port 1). The main function of the 140AY device is to accept Pulse Code
Modulation (PCM)/Adaptive Differential Pulse Code Modulation (ADPCM) samples and
compress/expand the samples using ADPCM. This test connects a Tone Generator to one port
(Announcement Port 1, the recording port), and a Tone Detector to another port (Announcement
Port 9). A tone is generated by the Tone Generator on the first port and looped through the
140AY device to the second port. The Tone Detector then responds with a tone present/absent
message. The 140AY Loop Around Test is repeated at three different speech compression
rates.
Since this test involves sending a tone through two different ports, the Playback Speech
Memory Array (PSMA) Test (#206) is run on the two ports first to make sure that they are
working properly. See
