SYS-LINK (System Links)
Issue 1 May 2002 8-1537 555-233-143
f. This error indicates that the link has experienced slow transmit rate
because the remote endpoint is busy. The effect of this error is that the
endpoint location may experience slower throughput rate and/or noisy
transmission. The system link is alarmed if 4 or more errors of this type are
detected within 10 minutes.
1. Ensure that the remote endpoint is functioning properly.
2. Follow the information in the previous section, ‘‘Common Procedure
for Repairing Link Problems’’ on page 8-1534 .
3. Clear errors and wait for 10 minutes.
g. This error indicates that the link has experienced slow transmit rate due to
excessive retransmission. Possible causes for this error may be that the
switch is overrunning the endpoint or that the endpoint is sick. The effect of
this error is that the endpoint location may experience slower throughput
rate. The system link is alarmed if 4 or more errors of this type are
detected within 10 minutes.
1. Follow the information in the previous section, ‘‘Common Procedure
for Repairing Link Problems’’ on page 8-1534 .
2. Clear errors and wait for 10 minutes.
h. This error indicates that the link has experienced slow transmit rate due to
unknown causes, meaning that the endpoint location may experience
slower throughput rate and the Packet Interface may experience backup or
congestion. The system link is alarmed if 4 or more errors of this type are
detected within 10 minutes.
1. Follow the information in the previous section, ‘‘Common Procedure

System Technician-Demanded Tests:
Descriptions and Error Codes
Testing for system links is different from the standard test procedures for MOs. In
addition to testing the system link MO, the user is allowed to test every component
in the path of the system link. There are two paths preserved for the link. The
current path, if present, represents the path traversed by the link currently. This
path is absent when the link is down. The other path, the faulted path, is present
if the link has ever gone down or never come up. If the link came up and went
down, then the faulted path is marked
present
. If the link never came up, the
faulted path is marked
Defaul
t. In either case, it represents the path on which
the link was attempted or established unsuccessfully.
