Speech Synthesis Memory Test (#166)
The encoded speech for the Speech Synthesis circuit pack is stored in on-board
read-only memory (ROM). A checksum is computed for each 32K speech
memory block and compared against a known checksum value. If every
computed checksum value is successfully compared against the stored checksum
values, the test passes. If, while testing the speech complex memory, the
on-board microprocessor finds a memory error, the test is terminated and a failure
is reported. This type of failure may affect other ports on the Speech Synthesis
circuit pack, resulting in errors or alarms on each port.

Result
Description / Recommendation
ABORT
Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
1000
ABORT
System resources required to run this test are not available. The port may be
busy with a valid call and therefore unavailable for certain tests. Wait until the
port is idle (amber LED is off) before retesting.
1. If the port is idle, retry the command at 1-minute intervals up to 5 times.
1019
ABORT
Test is already running on a different port, possibly due to background
maintenance activity. Only one of these tests may be active on a circuit pack at
a time.
1. Retry the command at 1-minute intervals up to 5 times.
2000
ABORT
Response to the test request was not received within the allowable time period.
2100
ABORT
Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
Any
FAIL
The computed checksum from the speech vocabulary ROM did not compare
correctly with the stored checksum. This type of failure may cause features
using the Speech Synthesis port’s speech services to malfunction and result in
degradation of synthesized speech quality ranging from insignificant to major.
1. Replace the circuit pack.
PASS
The computed checksum values were successfully compared against the
stored checksum values. User-reported troubles should be investigated using
other tests and by verifying other ports on this circuit pack are working
correctly.
