Issue 8.0, July 2002 Page 1 of 2
TAP-135
Clear (Optical Parameter) ‘Out-Of-Range’
NOTE:
This condition indicates that one or more of the operating parameters of a
RCVR, TRMTR, or REGENR circuit pack has exceeded the recommended
range.
1. At the CIT, select FAULT-Retrieve-Alarm to obtain an Active Alarms and
Status Report.
2. Is one or more of the conditions listed in Table A indicated in the report?
If YES, then find this second associated condition (identified below) in
Table A of TAP-102 and go to the referenced TAP.
If NO, then continue with Step 3.
NOTE:
This condition, by itself, does not indicate a failure with the FT-2000 network
element.
NOTE:
At an FT-2000 end terminal and at the CIT, select
PERFORMANCE-Retrieve-PM-Optics to obtain a report that shows the
transmit power, receive power, and the laser bias current with respect to time.
NOTE:
OC-48 optical lines can be tested by using optical line meters and/or optical time
domain reflectometers (OTDR) to help locate a fiber bend or cut.
3. Refer to local operating procedures for further guidance in addressing this
condition.
