Port Color Service State Description
Cyan (blue) Out-of-Service and Management, Loopback 
(OOS-MA,LPBK) (ANSI)
Locked-enabled,loopback (ETSI)
Port is in a loopback state. On the card in node or shelf 
view, a line between ports indicates that the port is in 
terminal or facility loopback (see Figure 12-5 and 
Figure 12-6). 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) Out-of-Service and Management, Maintenance 
(OOS-MA,MT) (ANSI)
Locked-enabled,maintenance (ETSI)
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 this service state for testing or to suppress 
alarms temporarily. Change the state to 
IS-NR/Unlocked-enabled; 
OOS-MA,DSBLD/Locked-enabled,disabled; or 
OOS-AU,AINS/Unlocked-disabled,automaticInService 
when testing is complete.
Gray Out-of-Service and Management, Disabled 
(OOS-MA,DSBLD) (ANSI)
Locked-enabled,disabled (ETSI)
The port is out-of-service and unable to carry traffic. 
Loopbacks are not allowed in this service state. 
Green In-Service and Normal (IS-NR) (ANSI)
Unlocked-enabled (ETSI)
The port is fully operational and performing as 
provisioned. The port transmits a signal and displays 
alarms; loopbacks are not allowed. 
Violet Out-of-Service and Autonomous, Automatic 
In-Service (OOS-AU,AINS) (ANSI)
Unlocked-disabled,automaticInService (ETSI)
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 this service state for the duration of the 
soak period. After the soak period ends, the port service 
state changes to IS-NR/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 AINS 
port will automatically transition to 
IS-NR/Unlocked-enabled when a signal is received for 
the length of time provisioned in the soak field.
