5. Restart the affected port network:
TONE-BD (Tone-Clock Circuit Pack)
● Restart the PN by resetting its Expansion Interface circuit pack using reset
port-network P level 2, using the port network’s number of the affected PN.
(Use the list cabinet C command to determine the port network’s number for a
given cabinet and carrier.)
6. Test the new IPSI or Tone-Clock circuit pack to verify that it is functioning properly, using
test tone-clock location long, and verify that the system is operational by
placing several phone calls. Where possible, try calls into, out from, and within the affected
port network.
Port Networks with Two Tone-Clock Circuit Packs
Notes:
1. Use list cabinet C to determine the port network’s number of the cabinet and carrier
containing the Tone-Clock circuit pack to be replaced. If both of a PN’s Tone-Clock circuit
packs need to be replaced, first replace and test the one in standby mode by either:
● Entering status port-network to display its status
● Making sure its amber LED is off
Make sure it is healthy and active before replacing the second one.
The active/standby state of a Tone-Clock circuit pack may also be determined by looking at its
LED. A continuously lit red LED on the Tone-Clock circuit pack indicates a reported fault on one
or more of the maintenance objects on the circuit pack. Flashing patterns of the yellow and
green LEDs correspond to the following service states:
Condition Tone-Clock
Circuit State
Flashing yellow 2.7 seconds on,
.3 seconds off
Flashing yellow .3 seconds on,
2.7 seconds off
Explanation
Active An external timing source is being used as
a synchronization reference. 1
Active The local oscillator on the 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.
Yellow LED off Standby The circuit pack is in standby mode,
(neither generating tones nor supplying
clocks).
