TONE-BD (Tone-Clock Circuit Pack)
The Tone-Clock circuit pack functionality is provided by two independent objects
in the same circuit pack. The tone generator provides all the tones needed by the
system and the clock generates the system clocks for the Time Division Multiplex
(TDM) Bus and aids in monitoring and selecting internal synchronization
references.
When resolving errors/alarms on the Tone-Clock circuit pack, the following should
be used also:
■
TONE-PT (Tone Generator) Maintenance documentation.
■
TDM-CLK (TDM Bus Clock) Maintenance documentation.
■
SYNC (Synchronization) Maintenance documentation.
The TN2182 is a combined Tone-Clock/Detector circuit pack that contains 8 ports
used for all-purpose tone detection. These ports are called Enhanced Tone
Receiver ports (ETR-PT) and are described in the documentation for ETR-PT.
Tone-Clock Circuit Packs
CMC systems have one Tone-Clock circuit pack in each port network. This is in
the A carrier. This Tone-Clock circuit pack generates clocks and provides system
tones for all carriers of the port network it resides on.
Italian Tone Settings (New ISPT Value)
The TN2182 allows International changes, 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.
