Port Color Service State Description
Cyan (blue) locked-enabled,loopbac
k
(Out-of-Service and Management, Loopback) Port is in a
loopback state. On the card in node view, a line between
ports indicates that the port is in terminal or facility
loopback (see Figure 4-3 on page 4-9 and Figure 4-4 on
page 4-10). Traffic is carried and alarm reporting is
suppressed. Raised fault conditions, whether or not their
alarms are reported, can be retrieved on the CTC
Conditions tab or by using the TL1 RTRV-COND
command.
Cyan (blue) locked-enabled,mainten
ance
(Out-of-Service and Management, Maintenance) Port is
out-of-service for maintenance. Traffic is carried and
loopbacks are allowed. Alarm reporting is suppressed.
Raised fault conditions, whether or not their alarms are
reported, can be retrieved on the CTC Conditions tab or by
using the TL1 RTRV-COND command. Use
locked-enabled,maintenance for testing or to suppress
alarms temporarily. Change the state to unlocked-enabled,
locked-enabled,disabled, or locked-disabled,Automatic In
Service when testing is complete.
Gray locked-enabled,disable
d
(Out-of-Service and Management, Disabled) The port is
out-of-service and unable to carry traffic. Loopbacks are
not allowed in this service state.
Green unlocked-enabled (In-Service and Normal) The port is fully operational and
performing as provisioned. The port transmits a signal and
displays alarms; loopbacks are not allowed.
Violet locked-disabled,Autom
atic In Service
(Out-of-Service and Autonomous, Automatic In-Service)
The port is out-of-service, but traffic is carried. Alarm
reporting is suppressed. The node monitors the ports for an
error-free signal. After an error-free signal is detected, the
port stays in locked-disabled,Automatic In Service state for
the duration of the soak period. After the soak period ends,
the port service state changes to unlocked-enabled.
Raised fault conditions, whether or not their alarms are
reported, can be retrieved on the CTC Conditions tab or by
using the TL1 RTRV-COND command. The Automatic In
Service port will automatically transition to
unlocked-enabled when a signal is received for the length
of time provisioned in the soak field.
