The normal sequence of PCM states leading to a fully synchronized connection
and incorporation of the port into the token path is shown in Figure 8-1. Note
that the minimum interval between interrogations is one second and that this
is not always fast enough to recover and display the complete sequence of
PCM
states.
Figure 8-1 Normal Sequence of PCM States
Ring_OP (Ring Operational)
Ring_OP shows the number of Ring_OP (Ring Operational) signals received.
This signal is generated when the station is incorporated into an operational
network.
XmitP (Transmit Packets)
Running pf_stat without an interval and count, displays the total number of
packets transmitted since the interface was activated. Running pf_stat with
an interval and count, displays the number of packets transmitted since the last
interrogation.
VERIFY Second state in the sequence leading to a synchronized connection.
ACTIVE Final state indicating that the port is successfully incorporated in the
token path.
TRACE PCM is localizing a stuck beacon condition.
