Notes:
Replacing the circuit pack is a service disrupting procedure. The test should be
run several times with more than one failure before the replacement policy
specified in the following notes is executed. Use the procedure described in
‘‘How to Replace a Tone-Clock Circuit Pack’’
in the TONE-BD section.
a. All the failure error codes marked with (a) will affect users. When the tone
generation facility fails, replace the faulty Tone-Clock promptly.
b. All the failure error codes marked with (b) are almost transparent to the
user. Users may or may not hear any noisy tones. This type of failure
affects other MOs. Maintenance may not be able to run on other objects
which use the tone generation facility (that is, Tone Detector Circuit Pack
maintenance). In this case, the Tone-Clock circuit pack can be replaced
as suitable to the customer.
c. Error code 115 may also be caused by TDM Bus corruption. This normally
means a physical problem with bent backplane pins, TDM/LAN Bus
cabling, or TDM/LAN Bus terminators. Such physical problems should
especially be suspected if board replacement or other physical activity
has occurred just before this error is observed.
Use
display errors
to look for errors on other circuit packs in the carriers
of the same Port Network as the Tone-Clock. If any are found, they should
be resolved if possible, and the Tone-Clock circuit pack retested. If this
does not clear the problem, the Tone-Clock circuit pack should be
replaced and the new one tested. If the problem persists, follow
instructions for TDM Bus maintenance in this manual.
111 (b) FAIL Generation of 1004-Hz low level invalid.
112 (b) FAIL Generation of 1004-Hz high level invalid.
113 (b) FAIL Generation of 2804-Hz level invalid.
115 (b,c) FAIL Generation of digital count sequence invalid.
120 (a) FAIL Generation of quiet tone failed.
1044 (a) FAIL DTMF generation failed to generate Digit 1 for the standby tone generator.
1045 (a) FAIL DTMF generation failed to generate Digit 5 for the standby tone generator.
1046 (a) FAIL DTMF generation failed to generate Digit 9 for the standby tone generator.
1047 (a) FAIL DTMF generation failed to generate Digit D for the standby tone generator.
PASS The tone generation facility is able to generate and transmit all the tones.
