TBRI-PT (TN2185 ISDN Trunk-Side BRI Port)
Issue 4 May 2002

555-233-123
h. Error Type (1537): The board received a bad Cyclical Redundancy Check
(CRC) over the D-Channel. This error is reported on a per-port basis.
When the CRC errors exceed 5 within 15 minutes, the port is taken out of
service for 5 seconds. If 5 more CRC errors are received within 15 minutes
of the first set of 5 errors, the port is taken out of service for 1 minute. If 5
more CRC errors are received within 15 minutes of the previous 5, the port
is taken out of service for 15 minutes.
This error is most likely due to a problem with backplane wiring, a noise
source, or no termination (an open circuit). It usually does not indicate a
problem with the circuit pack.
1. Check the backplane wiring.
2. If the problem persists escalate the problem.
i. Error Type (1538): This error occurs when a frame with a bad CRC is
received by the BRI trunk board. This error only occurs on a system that
switches the packet implementation of the D-channel over the TDM bus.
This error indicates an off board problem related to the packet
implementation of the TDM D-Channel (R6.2 and later).
j. Error Type (1793): The BRI Port Local TDM Loop Around Test (#619)
failed. Run the Long Test Sequence paying particular attention to the
results of the BRI TDM Port Loop Test (#619).
k. Error Type (2049): The Layer 2 Link Query failed. The test is repeated
every 15 minutes until it passes.
l. Error Type (2305): The Remote Layer 3 Query failed. The test is repeated
every 15 minutes until it passes.
m. Error Type (3073): A frame of information had to be repeated or deleted.
Slips usually occur when the received bit rate is not synchronized with the
TDM Bus clock.
n. Error Type (3585): The circuit pack detected an overflow of its receive
buffers. This error occurs only a system that switches the packet
implementation of the D-Channel over the TDM bus. This error indicates an
on board problem related to the packet implementation of the TDM
D-Channel (R6.2 and higher).
o. Error Type (3586): Each port can support up to three Terminal Endpoint
Identifiers (TEIs). Each channel on the port can request a TEI assignment
from the switch if it supports ISDN-BRI TEI assignment procedures. If
switch services gets a request for a fourth TEI on a port, it reports this
event to maintenance software and initiates TEI check procedures on the
port. Check to see if the correct number of channels are administered for
this port.
The user side supports automatic TEI assignment by the network. Both
fixed and automatic TEI assignment are supported on the network side.
