1Q08 GENERIC INTERCONNECTION AGREEMENT – 03/10/08
Additional caged Collocation Space may be requested in increments of fifty (50) square feet. For
cageless Collocation Space, Southern Light shall pay floor space charges based upon the
following floor space calculation: [(depth of the equipment lineup in which the rack is placed) + (0.5
x maintenance aisle depth) + (0.5 x wiring aisle depth)] x (width of rack and spacers). For
purposes of this calculation, the depth of the equipment lineup shall consider the footprint of
equipment racks plus any equipment overhang. AT&T will assign cageless Collocation Space in
conventional equipment rack lineups where feasible. In the event Southern Light’s collocated
equipment requires special cable racking, an isolated ground plane, or any other considerations
and treatment which prevents placement within conventional equipment rack lineups, Southern
Light shall be required to request an amount of floor space sufficient to accommodate the total
equipment arrangement.
8.8 Remote Site Bay Space. In a Remote Site, the bay space charge recovers the costs associated
with air conditioning, ventilation and other allocated expenses for the maintenance of the Remote
Site Location, and includes the amperage necessary to power Southern Light’s equipment.
Southern Light shall remit bay space charges based upon the number of bays requested. AT&T
will assign Remote Site Collocation Space in conventional Remote Site bay lineups where feasible.
8.9 Power
8.9.1 In a Central Office AT&T shall make available -48V DC power for Southern Light’s Collocation
Space at an AT&T BDFB. When obtaining DC power from an AT&T BDFB, Southern Light’s fuses
and power cables (for the A & B feeds) must be engineered (sized), and installed by Southern
Light’s AT&T Certified Supplier, in accordance with the number of fused amps of DC power
requested by Southern Light on Southern Light’s Initial Application and any Subsequent
Applications. Southern Light is also responsible for contracting with an AT&T Certified Supplier to
run the power distribution feeder cable from the AT&T BDFB to the equipment in Southern Light’s
Collocation Space. The AT&T Certified Supplier contracted by Southern Light must provide AT&T
with a copy of the engineering power specifications prior to the day on which Southern Light’s
equipment becomes operational (hereinafter “Commencement Date”). AT&T will provide the
common power feeder cable support structure between the AT&T BDFB and Southern Light’s
Collocation Space. Southern Light shall contract with an AT&T Certified Supplier who shall be
responsible for performing those power provisioning activities required to enable Southern Light’s
equipment to become operational, which may include, but are not limited to, the installation,
removal or replacement of the following: dedicated power cable support structure within Southern
Light’s Collocation Space, power cable feeds and terminations of the power cabling. Southern
Light and Southern Light’s AT&T Certified Supplier shall comply with all applicable NEC, AT&T TR
73503, Telcordia and ANSI Standards that address power cabling, installation and maintenance.
8.9.1.1 At a Remote Site, AT&T shall make available -48V DC power for Southern Light’s Remote
Collocation Space at a BDFB within the Remote Site Location. The charge for power shall be
assessed as part of the recurring charge for bay space, as referenced in Section 8.8 above. If the
power requirements for Southern Light’s equipment exceed the capacity available, then such
additional power requirements shall be assessed on an individual case basis.
8.9.2 In Florida Central Offices only, subject to technical feasibility, commercial availability and safety
limitations, AT&T will permit Southern Light to request DC power in five (5) amp increments from
five (5) amps up to one hundred (100) amps from the AT&T BDFB. However, in accordance with
industry standard fuse sizing, Southern Light may request that AT&T provision DC power of
seventy (70) amps or greater directly from AT&T’s main power board. The industry standard fuse
size (which is a circuit breaker on the main power board) available at an AT&T main power board
in all AT&T Premises is a two hundred twenty-five (225) amp circuit breaker.
