    DELINEATION SCHEDULE

    1. FOR LEAD-IN REQUIREMENTS REFER TO NBN LEAD-IN TRENCHING REQUIREMENTS DOCUMENT F002-31-11587 & OTHER RELEVANT DOCUMENTS. LIAISE WITH NBN FOR LOCATION OF START CONDUIT ON FOOTPATH.

    2. FOR NBN INSTALLATION REFER TO NBN BUILDING DESIGN GUIDE - NEW DEVELOPMENTS DOCUMENT NBN-TE-CTO-284, NBN-TE-CTO-194 & OTHER RELEVANT DOCUMENTS INCLUDING ACMA REQUIREMENTS. LIAISE WITH NBN THROUGHOUT. FOR MINIMUM SPACE ALLOCATIONS REFER TO AS/ANZ3084 UNLESS OTHERWISE VARIED BY NBN.

    3. PROVIDE LARGE RADIUS SWEEP BENDS OR SWEEPING CURVE IN CONDUIT FOR ALL CHANGES IN DIRECTION. MAINTAIN 2m SEPARATION FROM ANY POLE FOUNDATIONS. PROVIDE OVERSIZE SLEEVING TO CONDUITS THROUGH OR BELOW FOUNDATIONS TO PERMIT MOVEMENT WITHOUT DAMAGE. A MAXIMUM AGGREGATE OF 180o OF BENDS PERMITTED BETWEEN PITS (i.e. 2x 90o SWEEP BENDS).

    4. SEAL SERVICE DROP CONDUITS AT BOTH ENDS WITH CONDUIT PLUGS WITHIN PITS. SEAL ALL UNDERGROUND CONDUITS. CAP STUBS.

    5. PROVIDE 3mm ORANGE DRAW CORD TO ALL CONDUITS.

    6. CET:- WITHIN 1m OF EACH OUTDOOR NTD PROVIDE A TELECOMMUNICATIONS EARTH TERMINAL WITH 6mm2 MIN Cu EARTH CONDUCTOR TO MSB. LABEL "TELECOMMUNICATIONS BONDING CONDUCTOR" AT BOTH ENDS.

    7. PROVIDE FIBRE OPTIC PATHWAYS SUCH THAT NO FIBRE CABLE IS SELF SUPPORTING OVER A DISTANCE EXCEEDING 200mm

    8. PROVIDE P20 (23mm ID) WHITE CONDUIT PATHWAY FROM EACH APARTMENT NTD TO TELECOMMUNICATIONS RISER/ CLOSET. USE LARGE RADIUS SWEEP BENDS - NO MORE THAN 3x 90o BENDS & 50m ROUTE LENGTH BETWEEN ACCESSIBLE DRAW-IN POINTS. LABEL CONDUITS & DRAW CORDS WITH APARTMENT NUMBERS.

    9. WHERE TRAY IS USED FOR HORIZONTAL RETICULATION, PROVIDE ACCESS PANELS AT ALL CHANGES OF DIRECTION & AT 15m MAX INTERVALS. WERE CABLE TRAYS ARE SHARED PROVIDE 100mm SEPARATION TO NBN CABLING.
