1.3.66 LOCKOUT-REQ
• Not Alarmed (NA) (Condition)
The Lockout Switch Request on Facility/Equipment alarm occurs when a user initiates a lockout switch
request for an OC-N card or a lockout switch request on a UPSR at the path level. A lockout prevents
protection switching from occurring. Clearing the lockout will again allow protection switching to take
place. Clearing the lockout switch request clears the LOCKOUT-REQ alarm. This is an informational
alarm.
Procedure: Clear the Lockout Switch Request and the LOCKOUT-REQ Condition on an OC-N Card
Step 1 Display the CTC network view.
Step 2 Click Circuits tab and highlight the circuit.
Step 3 Click Edit and click the UPSR tab.
Step 4 From the Switch State menu, highlight Clear.
Step 5 Click Apply and click Close.
1.3.67 LOF (DS-1)
• Major, Service affecting
Loss of Frame (LOF) indicates that the receiving ONS 15454 has lost frame delineation in the incoming
data. If the LOF appears on the DS-1 card, the transmitting equipment may have its framing set to a
format that differs from the receiving ONS 15454.
Procedure: Clear the LOF Condition on the DS-1 Card
Step 1 Verify that the line framing and line coding match between the DS-1 port and the signal source.
a. In CTC, note the slot and port reporting the alarm.
b. Find the coding and framing formats of the signal source for the card reporting the alarm. You may
need to contact your network administrator for this information.
c. Display the card-level view of the reporting card.
d. Click the Provisioning > Line tabs.
