TONE-BD (Tone-Clock Circuit)

Port Networks with a Single Tone-Clock

Circuit Pack

This procedure is destructive.

1. Pull out the defective IPSI or Tone-Clock circuit pack. This will remove the

clocks and cause the system to activate emergency measures. If this is an

IPSI supported port network, use the busyout ipserver-interface

2. Insert a new IPSI or Tone-Clock circuit pack. The system will detect the

return of the clocks and will automatically recover as follows:

3. If the red LEDs come on but do not go off within 30 seconds, pull the circuit

pack out and reseat it. If the LEDs perform as expected this time, continue

with step 6. Otherwise, there may be a problem with the TDM bus;

possibly a bent pin in the IPSI or Tone-Clock circuit pack's slot. Follow the

directions in the TDM-BUS maintenance section.

4. If the red LEDs did light, as explained above, then go to Step 6. If the red

LEDs do NOT light, as explained above, then go on to Step 5.

5. Restart the affected port network:

6. Test the new IPSI or Tone-Clock circuit pack to verify that it is functioning

properly, using the test tone-clock UUC long command, 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.

All calls to and from the EPN will drop, and the EPN will activate

Emergency Transfer within about one minute. But the rest of the

system should operate normally.

The system will reset the EPN (EPN cold restart), and all of the

EPN's red LEDs will come on and go off within 30 seconds.

In an EPN, restart the EPN by resetting its Expansion Interface

circuit pack via the reset port-network PN# level 2 command,

using the port network's number of the affected EPN. (Use the list

cabinet UU command to determine the port network's number for a

given cabinet and carrier.)
