4. If the red LEDs did light, as exp lained above, then go to Step 6. If t he 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 rese t port-network PN# 2 command, using the
Port Network number of the affected EPN. (Use the list cabinet UU
command to determin e the Port Network number for a given
cabinet and c arrier.)
6. Test the new Tone-Clock circuit p ack to verify that it is functioning properly,
using the test tone-clock UUC long command, and verify that the system
is operational by plac ing several phone c alls. Where possible, try calls
into, out from, and within the affected Port Network.
