Notes:
Replacing the circ uit pack is a service d isrupting proc edure. The test should be
run several times with more than one failure before the replac ement policy
specified in the followi ng notes is executed. Use the procedure desc ribed in
‘‘How to Replace a Tone-Clock Circuit Pack’’ in the TONE-BD section.
a. All the failure error codes marked w ith (a) will affect users. When the tone
generation facility fails, replac e 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 b e able to run on other objec ts
which use the tone generation facility (that is, Tone Detector Circuit Pack
maintenance). In this case, the Tone-Clock circuit p ack can be rep laced
as suitable to the customer.
c. Error code 115 may also be c aused by TDM Bus corrup tion. This normally
means a physical prob lem with bent backp lane pins, TDM/LAN Bus
cabling, or TDM/LAN Bus terminator s. Such physical prob lems should
especially be susp ected if board replacement or other physic al activity
has occurred just b efore this error is observed.
Use display errors to look for errors on other circuit p acks in the carriers
of the same Port Network as the Tone-Clock. If any are found, they should
be resolved if possib le, and the Tone-Clock circuit pac k retested. If this
does not clear the prob lem, the Tone-Clock circuit pack should be
replaced and t he new one tested. If the problem p ersists, follow
instructions for TDM Bus maintenance in this manua l.
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 standb y tone generator.
1045 (a) FAIL DTMF generation failed to generate Digit 5 for the standb y tone generator.
1046 (a) FAIL DTMF generation failed to generate Digit 9 for the standb y 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.
