topological network configuration. Cisco does not recommend using its path protection 
feature in any particular topological network configuration.

Release 9.2.2 is supported only on the Cisco ONS 15454 MSTP platform.

There are two main types of standards-defined TL1 messages: command/responses and autonomous 
messages.

Command/Responses—These are initiated by a user and provide two parts: a request to the NE 
to set or get information, and a response from the NE containing completion or status codes and 
requested information. Request, or input messages are used to issue the request portions of
