TBRI-BD (ISDN Trunk-Side BRI Circuit Pack)
3. If the Circuit Pack Restart test (#594) fails, replace the circuit pack.
Error Type 2306: This is an error in a received frame from the Packet bus, most likely
caused by a packet bus problem, but may be due to a circuit pack fault. An invalid Link
Access Procedure Data (LAPD) frame error occurs if the frame contains a bad Cyclical
Redundancy Check (CRC). If bus parity errors occur, run the LANBIC Receive Parity Error
Counter Test (#595) to determine whether the condition has cleared. Determine whether the
problem is isolated to this circuit pack or is caused by Packet bus faults.
l. Error Type 3586: the server’s software detects an excessive number of uplink messages
from the TN2185 board within a certain time period. To prevent the faulty board from
flooding the switch with data, the switch software takes the board out of service and alarms
it. The switch software also tells the Archangel to ignore uplink messages from the board.
When the board is alarmed due to this error, the switch software periodically puts the board
back in service and tells the Archangel to process uplink messages from the board. If the
problem still exists, the software takes the circuit pack out of service again. If the circuit pack
does not exhibit the problem for a certain time period, then maintenance software resolves
the alarm and the circuit pack is left in service.
m. Error Type 3841: the circuit pack received an inconsistent down-link message (a bad
header, port number, data, sub-qualifier, or logical link) over the Control Channel.
n. Error Type 3842: the board is receiving data from the bus faster than it can distribute the
data to its endpoints, causing the FIFO RAM buffer to overflow. This error can occur
occasionally due to the statistical sizing of the buffers. If it occurs frequently, it may indicate
a LAPD parameter mismatch. LAPD should recover from this problem, but it may degrade
the performance of the LAN bus.
When this error is reported, maintenance reads and clears the board counter and logs the
problem in the maintenance error log.
o. Error Type 3843: bad translation RAM detected, but the call continues by using another
translation location. The circuit pack reports this error when it cannot update NPE/NCE
memory and read it back. This error is not service-affecting and can be ignored, but can
lead to other types of errors against this circuit pack.
