TONE-BD (Tone-Clock Circuit Pack)
International Settings
NOTE:
The following information is for non-IPSI port networks.
The TN780 Tone-Clock circuit pack uses three firmware configuration parameters
for international support. The following two are automatically set by the software
load for the targeted country:
The circuit pack's country-code (USA, ITALY, AUSTRALIA, etc.)
The circuit pack's companding mode (mu-Law or A-Law)
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.

Confirmation
In addition, the TN780 allows customizing 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 changes as the TN780 but allows the customizing
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.
Replacing the IPSI Circuit Pack
Replacing a TN2312 IPSI circuit pack's Tone clock circuit is a service-disrupting
procedure, because the Tone-Clock circuit is always needed to generate clocks
for its EPN, but only that EPN is affected. When the circuit pack is removed,
every call is immediately dropped, the EPN enters emergency transfer within one
minute, and no calls can be set up from or to that EPN.
When replacing a Tone-Clock circuit in an S8700 IP Connect system, always be
sure to replace it with the appropriate Tone-Clock circuit for the system. One
circuit-pack code is supported:
TN2312
555-233-142
New ISPT Value (default)
continuous
cadenced
The TN2312 IPSI circuit pack supplies Tone-Clock functionality for each
S8700 IP Connect EPN.
