ATTACHMENT 1 FOR SOLICITATION HC101319QA807

CIRCUIT SPECIFICATIONS: VENDOR WILL PERFORM ACCEPTANCE TESTING IN

ACCORDANCE WITH EITHER RFC-6815 OR ITU-T Y.1564. VENDOR MUST

TEST THE CIRCUIT FOR 24 HOURS IAW ITU-T.Y.1564 SPECIFICALLY,

FRAME SIZES OF 64,128,256,512,1024,1280 AND 1518 BYTES MUST BE

USED. THE TEST MUST VERIFY LENGTH OF RECEIVED FRAMES, INDICATE

NUMBER OF FRAMES DROPPED, NUMBER OF FRAMES RECEIVED OUT OF ORDER,

AND DUPLICATE FRAMES. TESTS MUST BE BI-DIRECTIONAL USING THE

SAME DATA RATE IN EACH DIRECTION. BURST TESTS MUST BE RUN TO

DETERMINE MINIMUM INTERVAL BETWEEN FRAMES THAT CAN BE PROCESSED

WITHOUT FRAME LOSS. A THROUGHPUT TEST IS REQUIRED INDICATING THE

FASTEST RATE AT WHICH TEST FRAMES CAN BE TRANSMITTED WITHOUT

FRAME LOSS. A SEPARATE THROUGHPUT TEST MUST BE RUN WITH FRAMES

ADDRESSED TO THE HARDWARE BROADCAST ADDRESS CONSTITUTING AT LEAST

1% OF THE TEST STREAM AND BE EVENLY DISTRIBUTED THROUGHOUT THE

TEST.

CIRCUIT SPECIFICATIONS/TESTING: A LATENCY TEST MUST BE RUN FOR

A PERIOD OF NO LESS THAN 120 SECONDS, AND REPEATED NO LESS THAT

20 TIMES. THE TEST STREAM FOR THE LATENCY TEST SHOULD BE RUN AT

THE THROUGHPUT RATE FOR CORRESPONDING FRAME SIZES FROM THE

THROUGHPUT TEST. END TO END LATENCY WILL BE CALCULATED AS THE

AVERAGE OVER THE 20 TEST RUNS. FRAME LOSS RATE TESTS SHOULD BE

RUN AT THE FRAME RATE CORRESPONDING TO THE MAXIMUM FRAME RATE,

AND REDUCED BY 10% INTERVALS UNTIL THERE ARE AT LEAST TWO

CONSECUTIVE RUNS IN WHICH NO FRAMES ARE LOST.THROUGHPUT TEST

RESULTS: PASSING RATE 100% FOR ALL FRAME BYTE SIZES EXERCISED.

FRAME LOSS RATE (%) RESULTS: FRAME LOSS RATE LESS THAN 0.01% FOR

ALL FRAME BYTE SIZES EXERCISED. LATENCY WILL BE MEASURED WILL BE

ACCORDING TO THE FOLLOWING MAXIMUM TRANSMISSION DELAY FOR ANY

CIRCUIT UP TO 500 MILES AIR-MILES IN LENGTH SHALL BE NO GREATER

THAN 13MS ONE-WAY AND ANY POINT-TO-POINT CIRCUIT LONGER THAN 500

AIR-MILES SHALL BE NO GREATER THAN 50MS ONE WAY WITHIN THE 48

CONTINENTAL STATES. ANY APS SWITCHOVER SHALL TAKE LESS THAN 50

MILLISECONDS MONTHLY AVAILABILITY SHALL BE NO LESS THAN 99.5%.
