f. Infrequent errors, at a rate which does not bring up an alarm, probably do
not affect service, unless there are customer complaints of no tones, or
incorrect tones which can not be explained in any other way. However, if
an alarm is raised because this error is being repeatedly logged, then the
circuit pack should be replaced. See
‘‘Replacing the IPSI or Tone-Clock
g. The system-parameters country-options administration requires a TN780
or TN2182 Tone-Clock or a TN2312 IPSI circuit pack, but the existing
Tone-Clock circuit does not provide the needed functionality. The Base
Tone Generation Set on page 1 or the custom tones beginning on page 2
of the system-parameters country options form may have values not
supported by the existing Tone-Clock.
This error (1281) indicates that the system parameters country-options
form has custom tones translated and that the alarmed tone board does
not support the customized tones. TN768 tone boards do not support any
customized tones. TN780 tone boards support up to 6 customized tones
using the following frequencies/levels only:
Silence
404Hz at 11.0 dB
350Hz at 17.25 dB
404Hz at 16.0 dB
