Using Technician Interface Scripts
2-284 117380-A Rev. A
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.
Next - 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.
