Notes:
Replacing an IPSI 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 Circuit Pack’’.
a. All the failure error codes marked with (a) may affect users. When the tone
generation facility fails in this way, the faulty Tone-Clock should be
replaced 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 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 IPSI 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.
