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:
■ In the PPN, restart the system via the
reset system 2
command.
■ In an EPN, restart the EPN by resetting its Expansion Interface
circuit pack via the
reset port-network
PN# 2
command, using the
Port Network number of the affected EPN. (Use the
list cabinet
UU
command to determine the Port Network number for a given
cabinet and carrier.)
6. Test the new 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.
