ANN-BD (Announcement Circuit Pack)
Locked Announcement Circuit Pack
The announcement circuit pack can exhibit a rare "locked" condition that renders
two of its ports unusable by software. One of these ports is the record port, thus
preventing any recording of announcements or execution of the save/restore
announcements commands. Software does not have any way of detecting this
condition and will attempt to use the ports.
When the circuit pack is in this state, the following symptoms is observed:
When attempting to record an announcement, you will hear the proper
record tone, but the announcement will not record. This will not be
apparent until an attempt is made to play the announcement back.
Performing a test board long will yield the following abort codes:
— Test #206 aborts on ports 1 and 9 with code 1024.
— Test #205 aborts on ports 1 and 9 with code 2000.
— Tests #209 and #210 abort with code 1024.
The save/restore announcements commands will time 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 with the following sequence of commands:
1. busyout board UUCSS (this command will drop every call to the
Announcement circuit pack)
2. reset board UUCSS
3. release board UUCSS
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 Looparound 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) [see "ANN-PT" for a description of this
test] is run on the two ports first to make sure that they are working properly.
