Notes:
Except in EPNs containing more than one IPSI or Tone-Clock circuit pack,
replacing an IPSI or Tone-Clock 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
‘‘Replacing the IPSI or Tone-Clock Circuit Pack’’
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 IPSI or
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 IPSI or Tone-Clock circuit packs, the faulty IPSI
or Tone-Clock circuit pack 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 IPSI or 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 maintenance).
In this case, the IPSI or Tone-Clock circuit pack can be replaced as suitable
to the customer.
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.
