Playback Speech Memory Array (PSMA) Test
(#206)
The PSMA test checks the integrity of a playb ack channel’s interfac e to the
speech memory and the TDM Bus. The SP has an internal buffer that contains a
specific 256-b yte sequence. During th is test, the byte sequence i s "played"
through the 140AY device onto the TDM Bus. A General Purpose Tone Detector is
used to confirm that the p roper sequence was p layed. This test is very
important. It is the only test that actually chec ks an Announcement Port’s ability
to play back an announc ement on the TDM Bus. If the test fails, the Tone
Detector returns the number of bytes that d id not match the expec ted sequence.
The larger the number, the more severe the prob lem with that port. If this test
fails, announcements played over this port should sound corrupted.
