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.
