LINE RATE: 622.08MB/S 20 PPM.

LINE CODE: OPTIC

FRAME FORMAT: SONET/STS-12

1. TEST AND ACCEPTANCE: FIBER OPTIC OC-12 CIRCUITS SHALL PASSA FULLY DOCUMENTED SATISFACTORY 72 HOUR SOAK TEST BY THE GOCAT SCOTT AFB, IL. PRIMARY: (C) 618-418-8691 (D) 418-8691.

2. TESTING PARAMETERS AND THRESHOLDS: THE FOLLOWING TESTING PARAMETERS SHALL BE MEASURED DURING TEST AND ACCEPTANCE.

TESTING. ERROR PERFORMANCE (AVAILABILITY, SES,DM, EFS) ANDLOSS OF BIT COUNT INTEGRITY SHALL BE MEASURED AND RECORDED OVER THE DURATION OF THE CONTIGUOUS 72 HOUR TESTING INTERVALAND SHALL BE MEASURED AND RECORDED PER DEFINITION IN ITURECOMMENDATION G.826 AND M.2100.
