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 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 or Tone-Clock Circuit Pack
Replacing a TN2312 IPSI circuit pack or Tone-Clock circuit pack is a
service-disrupting procedure in an EPN with a single Tone-Clock, because the
IPSI or Tone-Clock circuit pack is always needed to generate clocks for its EPN.
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 an IPSI or Tone-Clock circuit pack in an S8700 Multi-Connect
system, always be sure to replace it with the appropriate IPSI or Tone-Clock
circuit pack for the system. Four circuit-pack codes are supported:
Tone New ISPT Value (default) Old ISPT Value
Dial continuous cadenced
Confirmation cadenced continuous
TN768 This is a general-purpose Tone-Clock circuit pack for EPNs in an S8700
Multi-Connect system. It can be used in every situation, except as the
Master Tone-Clock circuit pack when a Stratum-3 clock is administered.
TN780 The Stratum-3 clock feature requires the use of this circuit pack code in
EPN 1. The Stratum-3 clock will operate only with this code as the Master
Tone-Clock circuit pack. The TN780 circuit pack is upward compatible
with the TN768 code, and can be used in any place a TN768 would be
allowed. The TN780 is used in many countries outside the U.S. where the
TN768 does not provide local tones.
TN2182 This Tone-Clock-Detector may be used anywhere a TN768 or TN780 is
used, with the exception of configurations requiring Stratum-3 clock. The
TN2182 may be used in all country configurations.
TN2312 The TN2312 IPSI circuit pack supplies Tone-Clock functionality for
S8700 Multi-Connect systems.
