Notes:
Except in Port Networks containing more than one Tone-Clock circuit pack,
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) may affect users if the failure is
on the active tone generator. When this type failure is detected, the
system will attempt to move the tone generation function to the alternate
Tone-Clock circuit pack, if one is present in the affected Port Network.
When the tone generation facility fails in this way, especially in a Port
Network without duplicated Tone-Clock circuit packs, the faulty
Tone-Clock should be replaced promptly.
b. All the failure error codes marked with (b) are almost transparent to the
user. Again, when this type failure is detected, the system will attempt to
move the tone generation function to the alternate Tone-Clock circuit
pack, if one is present in the affected Port Network. Users may or may not
hear any noisy tones. This type of failure affects maintenance on other
objects. 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.

(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.
