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 im plementation of the D-channel over the TDM bus.
This error indicates an off board p roblem related to the packet
implementation of the TDM D-Channel.
j. Error Type (1793): The BRI Port Local TDM Loop Around Test (#619)
failed. Run the Long Test Sequence paying par ticular 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 o r deleted.
Slips usually occur when the received bit rate is n ot 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 switc hes the packet
implementation of the D-Channel over the TDM bus. This error indi cates
an on board problem relate d to the packet imple mentation of the TDM
D-Channel.
o. Error Type (3586): Each port can support up to three Terminal Endpoint
Identifiers (TEIs). Each channel on the port c an request a TEI assignment
from the switch if it supports ISDN-BRI TEI assignment procedures. If
switch services gets a req uest for a fourth TEI on a port, it reports this
event to maintenance software and initiates TEI chec k procedures on the
port. Check to see if the c orrect number of channels are ad ministered for
this port.
The user side supports automatic TEI assignment by the network. Both
fixed and automatic TEI assignment are sup ported on the network sid e.
p. Error Type (3587)Service Profiler IDentifier (SPID) value is invalid or is a
duplicate of another SPID that is already initia lized at Layer 3 on the port.
SPIDs are not used on the TN2185 circuit pack. However there wil l be
related events.
q. Error Type (3588): The board receives D-Channel data from the bu s faster
than it can process the d ata. The FIFO RAM buffers overflowed. This error
occurs occ asionally due to the statistical sizing of the buffers; however,
frequent occurrenc es may indicate a LAPD parameter mismatc h between
the two endpoints of a pac ket-switched connec tion. Run the Long Test
Sequence paying p articular attention to the results of the Receive FIFO
Overflow Test (#625).
r. Error Type (3589): The BRI Port Local LAN Loop Around Test (#618) failed.
Run the Long Test Sequence and pay partic ular attention to the results of
Test #618.
