Southern Light
1Q08 GENERIC INTERCONNECTION AGREEMENT – 03/10/08
all Subsequent Collocation Applications, which may either increase or decrease the originally
requested, and any subsequently augmented, number of fused amps of power capacity requested,
consistent with Commission orders.
8.3.3 AT&T shall have the right to inspect and inventory any DC power fuse installations at an AT&T
BDFB or DC power circuit installations at AT&T’s main power board for any Southern Light
collocation arrangement, to verify that the total number of fused amps of power capacity installed
by Southern Light’s AT&T Certified Supplier matches the number of fused amps of DC power
capacity requested by Southern Light on Southern Light’s Initial Application and all Subsequent
Applications. If AT&T determines that Southern Light’s AT&T Certified Supplier has installed more
DC capacity than Southern Light requested on its Initial Application and all Subsequent
Applications, AT&T shall notify Southern Light in writing of such discrepancy and shall assess
Southern Light for the additional DC power fuse/circuit capacity from the Space Acceptance Date
or Space Ready Date, whichever is applicable pursuant to Section 8.3.1 above, for the most recent
Initial Application or Subsequent Application, submitted for such collocation arrangement. AT&T
shall also revise Southern Light’s recurring DC power charges, on a going-forward basis, to reflect
the higher number of fused amps of power capacity available for the collocation arrangement.
8.4 Nonrecurring Charges. Unless specified otherwise herein, AT&T shall assess nonrecurring
charges, including all application fees, within thirty (30) days of the date that AT&T provides an
Application Response to Southern Light or on Southern Light’s next scheduled monthly billing
statement, if Southern Light’s current month’s billing cycle has already closed. Nonrecurring
charges associated with the processing of the Firm Order for collocation space preparation (Firm
Order Processing Fee) shall be billed by AT&T within thirty (30) days of AT&T’s confirmation of
Southern Light’s BFFO or on Southern Light’s next scheduled monthly billing statement.
8.5 In some cases, Commissions have ordered AT&T to separate its disconnect costs and its
installation costs into two separate nonrecurring charges. Accordingly, unless otherwise noted in
this Agreement, the Commission ordered disconnect charges will be applied at the time the
disconnect activity is performed by AT&T, regardless of whether or not a disconnect order is issued
by Southern Light. Disconnect charges are set forth in Exhibit B of this Attachment.
8.6 Central Office Space Preparation. Space preparation fees consist of a nonrecurring charge for
Firm Order Processing and monthly recurring charges for Central Office Modifications and
Common Systems Modifications. For all states except Florida, Southern Light shall remit the
payment of the nonrecurring Firm Order Processing Fee coincident with the submission of
Southern Light’s BFFO. In Florida, the nonrecurring Firm Order Processing Fee will be billed by
AT&T, pursuant to Section 8.4 above. The monthly recurring charge for Central Office
Modifications will be assessed per arrangement, per square foot, for both caged and cageless
physical Collocation Space. The monthly recurring charge for Common Systems Modifications will
be assessed per arrangement, per square foot for cageless physical Collocation Space and on a
per cage basis for caged physical Collocation Space. These charges recover the costs associated
with preparing the Collocation Space, which includes, but is not limited to, the following items: a
survey, engineering of the Collocation Space, and design and modification costs for network,
building and support systems.
8.7 Central Office Floor Space. The Floor Space Charge includes reasonable charges for lighting,
HVAC, and other allocated expenses associated with maintenance of the AT&T Premises;
however, this charge does not include any expenses associated with AC or DC power supplied to
Southern Light’s Collocation Space for the operation of Southern Light’s equipment. For caged
physical Collocation Space, Southern Light shall pay floor space charges based upon the number
of square feet enclosed. The minimum size for caged Collocation Space is fifty (50) square feet.
