ATTACHMENT 1 FOR SOLICITATION HC101319QA099

CIRCUIT SPECIFICATIONS: CONUS NO JUMBO FRAME ETHERNET

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.

O. CIRCUIT SPECIFICATIONS CONTINUED: 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%.
