TONE-PT (Tone Generator)
NOTE:
Replacing the tone/clock circuit pack requires a special procedure which is
described in the documentation for TONE-BD. That section also describes
the LED display for this board.
The tone generator resides on the Tone/Clock circuit pack and provides all system
tones such as dial tone, busy tone, and so on. If an active tone generator fails, its
port network may not have tones (see the Tone Generator Transmission Test
#40). For instance, a user may go off-hook and hear no dial tone. This problem
will affect only users on the same port network in which the faulty Tone-Clock
circuit pack resides. The system will be able to process certain type of calls (that
is, internal calls will succeed while outgoing calls will not).
The Tone-Clock circuit pack also provides the clocks for the system and can serve
as the synchronization reference. Therefore, when resolving alarms on the
Tone-Clock circuit pack, the TDM-CLK (TDM Bus Clock) and SYNC
(Synchronization) Maintenance documentation should be utilized as well as the
TONE-BD (Tone-Clock Circuit Pack) Maintenance documentation.
