CAUTION: If
TONE-BD (Tone-Clock Circuit Pack)
5. To verify that the new Tone-Clock circuit pack can generate clocks for the system, switch to
the new Tone-Clock with set tone-clock location override, and enter test
tone-clock location. If the new Tone-Clock circuit pack is able to generate system
clocks, there will be no system disruption.
! CAUTION:
the new Tone-Clock circuit pack is not able to generate system clocks, this
procedure becomes destructive. The system will detect a loss of clock and
recover by resetting the PN (PN cold restart).
After the restart, the faulty Tone-Clock circuit pack will be in standby mode.
6. Place several phone calls.
IPSI/Tone Clock LED States
For the TN2312 IPSI circuit pack, there are four LEDs on the IPSI’s faceplate. The top three
LEDs are the standard ones found on any TN circuit pack. The fourth LED imitates the
TN2182B Tone-Clock’s amber LED. The active/standby state of an IPSI or Tone-Clock circuit
pack may also be determined by looking at its LEDs. A continuously lit red LED on the circuit
pack indicates a reported fault on one or more of its MOs. Flashing patterns of the yellow and
green LEDs correspond to the following service states:

Explanation
Active An external timing source is being used
as a synchronization reference 1 .
Active The local oscillator on the IPSI or
Tone-Clock circuit pack is being used as
a synchronization reference.
Yellow on continuously Active The circuit pack has been reset but has
not been told which synchronization
source to use.
S8700-series Fiber-PNC: yellow LED
off
Standby The circuit pack is in standby mode,
(neither generating tones nor supplying
clocks).
