February 2003
Probable Causes
CPX and Class 5 switch
connection has been lost.
Switch and CPX do not
agree on which link is
active on TMC or EOC.
Probable Causes
Software error occurred
on the CP module,
causing the ATM module
to initialize improperly.
ATM module is faulty.
Probable Causes
The MP module is not
connected to the LAN.
The LAN is down.
Faulty cable between CPX
and another LAN device.
The MP module is faulty.
Same as for abnormal MP,
XMT, and RCV indicator
states listed in this table.
Corrective Action
Verify that the interface group is active
in the switch.
Have the switch force a PPS switch on
the TMC or EOC link.
Corrective Action
1. Turn the CPX-1000 rear circuit
breaker switch off, then on again.
2. After the system initializes, verify
that the ATM module
indicators are lit or flashing.
Replace the ATM module (see
Troubleshooting on page 4-6).
Corrective Action
Connect the Ethernet jack of the MP
Transition card to the LAN.
Problem is in the LAN, external to the
CPX. Contact the LAN administrator
to determine cause.
Replace the cable between the MP
Transition card and the LAN device
with an identical cable.
Replace the card (see
an MP Card on page 5-10)
Take the corrective actions described
above.
