TEST PATTERN.

(K) THE VENDOR WINNING AWARD OF THIS OC-3C SERVICE MUST HAVE A 24X7 NETWORK

OPERATIONS CENTER.

(L) THE OC-3C SERVICE WILL BE ACCEPTED ON BEHALF OF THE GOVERNMENT BY DISA

GOC IP "B" AT SCOTT AFB, IL. AFTER COMPLETION OF SATISFACTORY TEST BY DISA GOC

IP "B": (C) 618-418-8627, (D) 418-8627.

MINIMUM TECHNICAL SPECIFICATIONS:

SPECIFIC FORMAT TO BE USED IS: LINE RATE: 155.52MB/S 20 PPM. LINE CODE: OPTICAL.

FRAME FORMAT. SONET/STS-3C

1. TEST AND ACCEPTANCE: FIBER OPTIC OC-3C CIRCUITS SHALL PASS A FULLY

DOCUMENTED SATISFACTORY 72 HOUR SOAK TEST BY THE ATM NETWORK OPERATIONS

CENTER IT&A.

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 99.98%. 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): THE ROUND TRIP DELAY (RTD) FOR THIS DISA IP

BACKBONE CIRCUIT WILL BE MEASURED IN MILLISECONDS FROM THE CUSTOMERS

SERVICE DELIVERY POINT (SDP) SITE-A TO THE CUSTOMERS SERVICE DELIVERY POINT

(SDP) SITE-Z. THE RTD SHALL BE LESS THAN OR EQUAL TO 10 MILLISECONDS TO

EFFECTIVELY SUPPORT THE GOVERNMENT'S MISSION.
