tones will be used for dial and confirmation tones. Values for dial confirmation
tone can be set independently on the change system-parameters
miscellaneous form. Whenever such changes are made, the effects are
immediately enforced on all TN780 Tone-Clock circuit packs without disrupting
tone or timing services.
Italian Tone Settings (New ISPT Value)
In addition the TN780 allows customization of up to six system tones in order to
meet specific country needs. These changes are made via the change
system-parameters country-options form.
The TN2182 allows the same International changes as the TN780 but allows the
customization of up to 24 system tones in order to meet specific country needs.
These changes are made via the change system-parameters country-options
form.
How to Replace a Tone-Clock Circuit Pack
Replacing the Tone-Clock circuit pack is a service-disrupting procedure on Port
Networks with a single Tone-Clock, because the Tone-Clock circuit pack is
always needed to generate clocks for its network. For EPN Tone-Clock
replacement where no second Tone-Clock circuit pack exists, only that EPN is
affected. When the circuit pack is removed, all calls are dropped immediately,
the EPN enters emergency transfer within one minute, and no calls can be set up
from or to that EPN. However, if the PPN Tone-Clock is removed for replacement
in a Standard Reliability Option system, the System Emergency Transfer feature
is activated within milliseconds, and the entire system is disrupted; no calls can
be placed, and existing calls are dropped.
