MINIMUM TECHNICAL SPECIFICATIONS:

SPECIFIC FORMAT TO BE USED IS: LINE RATE: OC-48C/ 20 PPM. LINE CODE: OPTIC FRAME FORMAT: SONET/STS-48C

1. TEST AND ACCEPTANCE: FIBER OPTIC OC-48C CIRCUITS SHALL PASS A FULLY DOCUMENTED SATISFACTORY 72 HOUR SOAK TEST BY THE CONUS AT SCOTT AFB, IL.

2. TESTING PARAMETERS AND THRESHOLDS: THE FOLLOWING TESTING PARAMETERS SHALL BE MEASURED DURING TEST AND ACCEPTANCE TESTING. ERROR PERFORMANCE (AVAILABILITY, SES, DM, EFS) AND LOSS OF BIT COUNT INTEGRITY SHALL BE MEASURED AND RECORDED OVER THE DURATION OF THE CONTIGUOUS 72 HOUR TESTING INTERVAL AND SHALL BE MEASURED AND RECORDED PER DEFINITION IN ITU RECOMMENDATION G.826 AND M.2100.

3. ERROR PERFORMANCE: ERROR PERFORMANCE SHALL BE BETTER THAN THE FOLLOWING PARAMETER THRESHOLDS TO BE ACCEPTABLE: AVAILABILITY SHALL BE GREATER THAN 99.5% OR BETTER SEVERELY ERRORED SECONDS (SES) SHALL BE LESS THAN 0.02% DEGRADED MINUTES (DM) SHALL BE LESS THAN 0.2% ERROR FREE SECONDS (EFS) SHALL BE GREATER THAN 99%

4. LOSS OF BIT COUNT INTEGRITY (LBCI): LOSS OF BIT COUNT INTEGRITY SHALL BE MONITORED ONLY BY THE FOLLOWING METHOD: USING TEST EQUIPMENT WHICH CAN DETECT AND MEASURE THE OCCURRENCE OF THE INSERTION OR DELETION OF ONE OR MORE BITS INTO THE DIGITAL BIT STREAM, ON MANY MANUFACTURERS BERT TEST EQUIPMENT THIS IS MONITORED USING THE "PATTERN SLIP" PARAMETER WHERE EVERY OCCURRENCE OF A PATTERN SLIP "EVENT" MARKS THE OCCURRENCE OF A LBCI (RATHER THAN THE RAW TOTAL NUMBER OF PATTERN SLIPS ACCUMULATED OVER A TESTING INTERVAL)

5. MEAN TIME TO LOSS OF BIT COUNT INTEGRITY (MTTLBCI) SHALL BE GREATER THAN 24 HOURS.

6. ROUND TRIP DELAY (RTD): RTD SHALL BE MEASURED OVER THE OC-48C CIRCUIT AND SHALL BE LESS THAN OR EQUAL TO (10) MILLISECONDS.
