9-1782TONE-BD (Tone-Clock Circuit Pack)

The third configuration parameter is used only for Italy (country code: ITALY), and
selects whether
new
versus
old
ISPT (Istituto Superiore Poste Telegrafi) 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.
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 internation 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 the 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.
