If you didn't happen to know what the code means - looks to me like it is suggesting replacing the card and/or PE
Good luck! Sounds intermittent to me
BSD0206 loop: l1 l2 ln Loop unable to receive speech from l1, l2, etc. Minor alarm lamp lit on
attendant console. Probable fault cause: 1. Network card for loop l 2. If you
cannot receive only one loop (l1), there is a possible intermittent fault in the
Network card for loop l1. This is the expected fault type if any other loops
cannot receive l1 or if L1 appears in a BSD0110 message. 3. If only one loop
(l1) cannot be received, possible intermittent fault in one of the peripheral
buffer connected to loop l1 4. All other network, conference and TDS cards in
the same group.
Action: The following actions correspond numerically to the fault locations listed
above: 1. Go to LD 32. Use the commands STAT l and ENLL l to identify and
enable disabled loops. Replace the Network card if loops remain disabled. 2. Go
to LD 32. Use the commands STAT l and ENLL l to identify and enable disabled

loops. Replace the Network card if loops remain disabled 3. Replace each
Peripheral Buffer in turn, starting with the one on the highest numbered PE shelf.
The test should then be allowed to run long enough to indicate whether the
problem will persist. 4. CFN card status may be checked in LD 34. TDS card
status may be checked in LD 38.
Severity: Critical. Critical to Monitor: Yes. SNMP trap: Yes
