Notes:
a. The Announcement circuit pack can exhibit a condition that does not allow
recording.
If the circuit pack gets locked into this state (this is an extremely rare
condition), two of the Announcement Ports on the circuit pack will be
unusable by software, one of which is the record port. Also, save/restore
announcements will not work, since the record port looks busy to the
circuit pack. Note that software does not have any way of knowing this,
and attempts to use the ports.
If the circuit pack is locked into this state, the following symptoms are
observed:
1. When attempting to record an announcement, users hear the
proper record tone, but the announcement do not record (they do
not know it until the announcement is played back).
2. Performing a test board long when the circuit pack is in this state
yield the following abort codes:
■ Ports 1 AND 9 abort Test #206 with code 1024
■ Ports 1 AND 9 abort Test #205 with code 2000
■ Board level Tests #209 and #210 abort with code 1024
3. The save/restore announcements command times out with:
Error encountered, can’t complete request
The Announcement circuit pack lock-up can be cleared remotely by
performing a soft reset to the circuit pack:
■ busyout board PCSS (this command drops all calls in progress on
the Announcement circuit pack)
■ reset circuit pack using the reset board PCSS command
■ release circuit pack using the release board PCSS command
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.
