Applicable TL1 Messages for SONET Network Elements
Document Number SR-NWT-002723
Issue Number 01
Issue Date Jun 1993
ABSTRACT: Given the decision to support a transition to Open Systems Interconnection/Common Management Information Service Element (OSI/CMISE), a
limited set of Transaction Language 1 (TL1) messages was defined for Synchronous Optical Network (SONET) Network Elements (NEs). This
message set permits network providers to establish services, to monitor the SONET network for failures, and to perform needed
administrative tasks associated with maintaining and monitoring NEs in simple SONET architectures: point-to-point, linear chain, tree,
and path switched ring.
Therefore, this Special Report (SR) is produced with the following objectives:
- To provide the Telcordia view of how suppliers may apply or map SONET requirements to specific TL1 messages supporting
implementation of these specific requirements.
- To identify those requirements for which TL1 messages do not exist. In some cases, the existing message set can be extended to
support the requirement. In others, new messages will be needed.
