or DC power supplied to OTI’s Collocation Space for the operation of OTI’s<br />

equipment. For caged physical Collocation Space, OTI shall pay floor space<br />

charges based upon the number of square feet enclosed. The minimum size for<br />

caged Collocation Space is fifty (50) square feet. Additional caged Collocation<br />

Space may be requested in increments of fifty (50) square feet. For cageless<br />

Collocation Space, OTI shall pay floor space charges based upon the following<br />

floor space calculation: [(depth of the equipment lineup in which the rack is<br />

placed) + (0.5 x maintenance aisle depth) + (0.5 x wiring aisle depth)] x (width of<br />

rack and spacers). For purposes of this calculation, the depth of the equipment<br />

lineup shall consider the footprint of equipment racks plus any equipment<br />

overhang. BellSouth will assign cageless Collocation Space in conventional<br />

equipment rack lineups where feasible. In the event OTI’s collocated equipment<br />

requires special cable racking, an isolated ground plane, or any other<br />

considerations and treatment which prevents placement within conventional<br />

equipment rack lineups, OTI shall be required to request an amount of floor space<br />

sufficient to accommodate the total equipment arrangement.<br />

8.7.1 BellSouth shall make available –48 Volt (-48V) Direct Current (DC) power for<br />

OTI’s Collocation Space at a BellSouth BDFB. When obtaining DC power from a<br />

BellSouth BDFB, OTI’s fuses and power cables (for the A & B feeds) must be<br />

engineered (sized), and installed by OTI’s BellSouth Certified Supplier, in<br />

accordance with the number of fused amps of DC power requested by OTI on<br />

OTI’s Initial Application and any Subsequent Applications. OTI is also<br />

responsible for contracting with a BellSouth Certified Supplier to run the power<br />

distribution feeder cable from the BellSouth BDFB to the equipment in OTI’s<br />

Collocation Space. The BellSouth Certified Supplier contracted by OTI must<br />

provide BellSouth with a copy of the engineering power specifications prior to the<br />

day on which OTI’s equipment becomes operational (hereinafter “Commencement<br />

Date”). BellSouth will provide the common power feeder cable support structure<br />

between the BellSouth BDFB and OTI’s Collocation Space. OTI shall contract<br />

with a BellSouth Certified Supplier who shall be responsible for performing those<br />

power provisioning activities required to enable OTI’s equipment to become<br />

operational, which may include, but are not limited to, the installation, removal or<br />

replacement of the following: dedicated power cable support structure within<br />

OTI’s Collocation Space, power cable feeds, and terminations of the power<br />

cabling. OTI and OTI’s BellSouth Certified Supplier shall comply with all<br />

applicable NEC, TR 73503, Telcordia and ANSI Standards that address power<br />

cabling, installation, and maintenance.<br />

8.7.2 In Florida only, pursuant to technical feasibility, commercial availability, and safety<br />

limitations, BellSouth will permit OTI to request DC power in five (5) amp<br />

increments from five (5) amps up to one hundred (100) amps from the BellSouth<br />

BDFB. However, in accordance with industry standard fuse sizing, OTI may<br />
