Issue 1 June 2005 543
1. If the system has duplicated PNC:
a. Test the ATM-EI (test board location l).
b. If Error 3585 is detected again, or if the board is not recognized anymore, replace the
ATM-EI circuit pack.
2. If the system does not have duplicated PNC and the circuit pack is in a PN:
a. Replace the ATM-EI circuit pack.
Error Type 3586: Framer Looparound test (#1260) failed.
Aux Data (Error Code 3586 only):
3. If Error Type 3586 is detected again, replace the circuit pack.
v. Error Type 3841: The board received a message from the switch that it does not recognize,
and the board responded with an inconsistent down link error message. This error does not
affect service, and no action is required.
w. Error Type 3842: The circuit pack received data from the packet bus faster than it could
distribute the data to its endpoint. This circuit pack should be able to recover by itself, and
no action is necessary.
x. Error Type 3843: The firmware on the circuit pack is reporting a resource that is low. This
error does not affect service and no action is required.
y. Error Type 3999: The circuit pack sent a large number of control channel messages to the
switch within a short period of time.
Aux Data Description
2 Packet path failed
3 Circuit path failed
4 TDM loop cannot be created
5 Packet loop cannot be created
If Then
Error Type 1538 is also
present
Circuit pack is taken out of service
Error Type 1538 is absent Circuit pack is not taken out of service, but has generated
50% of the messages necessary to be considered
hyperactive.
This can be normal during heavy traffic.
If the error is logged during light traffic, it can indicate a
problem with the circuit pack or the equipment attached to it.
