Condition Code Responses

3.1.1 Summary
Use this section to respond to conditions reported by the FLM 150 ADM system
(with the exception of FASTLANE ™applications). When the condition code
indicates an alarm event, this section provides trouble-clearing information.
Transient and standing conditions are also indicated by condition codes and in
some cases are associated with an alarm condition. General information about
the condition codes is presented. This is followed by suggested procedural steps in
clearing troubles. The majority of this section consists of the FLM 150 ADM
alarm and status message condition codes, which are presented in alphabetical
order. Each is accompanied by a table that provides the following:
• Access identifier (AID) type
• Direction of signal on which trouble (or trouble indicator) appears
• Probable cause(s)
• Suggested corrective action(s)
For some condition types, such as the bit error rate (BER) condition types,
additional information before the table explains how to interpret the FLEXR
TL1 message.
Note: Although all condition types reflect near-end messages, the source of a problem may
be at a remote location or in near-end tributary equipment.
For responding to alarms and conditions relating to FASTLANE applications,
refer to the FASTLANE I practice, FJTU-320-515-110, and FASTLANE II
practice, FJTU-320-515-111.
