3-104ANN-BD (Announcement Circuit Pack)
3
Notes:
a. The Announcement circuit pac k can exhibit a conditi on that does not allow
recording .
If the circuit pac k gets locked into this state (this is an extremely rare
condition), two of the Announc ement Ports on the circuit pac k will be
unusable by software, one of whic h is the record port. Also, sa ve/restore
announcements will not work, since the record p ort looks busy to the
circuit pack. Note that software does not have any way of knowing thi s,
and attempts to use the por ts.
If the circuit pac k is locked into this state, the following symptoms are
observed:
1. When attempting to record an announc ement, users hear the
proper record tone, b ut the announcement do not rec ord (they do
not know it until the announcement is pla yed back).
2. Performing a test board long when the circuit pack is in this state
yield the following abor t 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 cod e 1024
3. The save/restore announcements command times out with:
Error encountered, can’t complete request
The Announcement circuit pac k lock-up can be cleared remotely by
performing a soft reset to the c ircuit pack:
■busyout board PCSS (this command drops all calls in progress on
the Announcement circuit p ack)
■reset circuit pack using the reset board PCSS command
■release circuit pack u sing the release board PCSS command
140AY Loop Around Test (#210)
This test checks the integrity of the rec ord channel on the Announc ement circuit
pack (Announcement Port 1). The main func tion of the 140AY device is to accep t
Pulse Code Modulation (PCM)/Adaptive Differential Pulse Cod e Modulation
(ADPCM) samples and comp ress/expand the samples using ADPCM. This test
connects a Tone Generator to one port (Announcement Port 1, the rec ording
port), and a Tone Detector to another port (Announc ement 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 comp ression rates.
