DEFINITY ECS Release 8.2 Maintenance for R8.2csi 
555-233-119  Issue 1
April 2000
Maintenance Objects 
3-238ATM-TRK (Circuit Emulation Service Circuit Pack) 
3
If the error occurs 3 times in 10 minutes, the board is isolated from the 
Packet Bus and the board is alarmed. To clear the alarm:
1. Restore this circuit pack to the Packet Bus with this command 
sequence:
a. busyout board UUCSS
b. reset board UUCSS
c. test board UUCSS long
d. release board UUCSS
2. If the problem persists and there are no PKT-BUS or port alarms, 
replace the circuit pack.
k. Error Type 1538: The ATM-TRK circuit pack is hyperactive (sending an 
abnormal number of control messages to the processor). Use the 
following command sequence for this ATM-TRK circuit pack:
1. busyout board UUCSS
2. reset board UUCSS
3. test board UUCSS long
4. release board UUCSS
5. If this error persists, replace the circuit pack.
l. Error Type 1794: LANHO transmit FIFO overflow. The circuit pack’s 
transmit buffers have overflowed. 
1. Run 
test board UUCSS r 5
.
m. Error Type 2049: ACL Link Failure (link is down). The ATM Control Link 
(ACL) has failed, communication has been interrupted between the SPE 
and the ATM-TRK circuit packs on the system, and signaling-group 
parameters are not communicated across the packet bus. 
1. Check the PKT-BUS (Packet Bus) and SYS-LINK (System Link) 
maintenance objects, and follow the repair procedures indicated.
2. Run 
test board UUCSS
 against the ATM-TRK circuit pack.
n. Error Type 2306: too many parity errors in data received from the 
LAN/packet bus. 
If Then
Test #598 fails Replace the circuit pack.
If Then
Test 598 fails. Follow the repair procedures suggested for that 
test.
