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
‘‘How to Replace a Tone-Clock Circuit
Pack’’ in the TONE-BD section.
g. The system-parameters country-options administration are setup such that
a TN780 or TN2182 are required and the existing tone-clock circuit pack
will 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
