Physical State State of Physical Connection Management (PCM) for each port

within SMT. PCM initializes the connection of neighboring ports

and manages signaling between ports. PCM provides the necessary

signaling to initialize a connection, withhold a marginal

connection, and support maintenance features. PCM passes

through a variety of states, as follows:

•

Off

- Initial state of PCM.

•

Break

- Starting a PCM connection.

•

Trace

- Localizing a stuck beacon condition, which indicates that

the interface doesn’t see the token. This state should be a

transient condition. If it persists, contact your customer service

representative.

•

Connect

- Synchronizing the ends of the connection for the

signaling sequence.

•

- Separating the signaling performed in the SIGNAL state.

•

Signal

- Communicating individual bits of information across the

connection.

•

Join

- Assuring that both ends of the connection enter the

ACTIVE state together when signaling has completed.

•

Verify

- Leading to an active connection.

•

Active

- Incorporating the port into the token path.

•

Maint

- Detecting maintenance state.

Link Error Monitor Count Number of times a link has been rejected.

Elasticity Buffer Errors Number of elasticity buffer errors for a specific Physical Layer

Protocol (PHY). The elasticity buffer tracks clock tolerances

between stations.

Link Confidence Count Number of consecutive times the link confidence test has failed

during Connection Management.
