15.0 Billing Arrangements for Termination of Section 251(b)(5), Optional EAS, ISP-Bound, and Transit Traffic
15.1 In SBC-TEXAS each Party, unless otherwise agreed, will calculate terminating interconnection minutes of
use based on standard switch recordings made within the terminating carrier’s network for Section 251(b)(5)
Traffic, Optional EAS Traffic, ISP-Bound Traffic and Transit Traffic. These terminating recordings are the
basis for each Party to generate bills to the other Party. If CLEC does not have the technical ability to
correctly generate bills from terminating recordings, the terminating carrier shall use any method agreed
upon between the Parties.
15.2 For Option 1, ISP-Bound Traffic will be calculated using the 3:1 Presumption as outlined in Sections 1.5.3
above.
15.3 The measurement of minutes of use over Local Interconnection Trunk Groups shall be in actual
conversation seconds. The total conversation seconds over each individual Local Interconnection Trunk
Group will be totaled for the entire monthly bill and then rounded to the next whole minute.
15.4 In the event of a loss of data, both Parties shall cooperate to reconstruct the lost data within sixty (60) days
of notification and if such reconstruction is not possible, shall accept a reasonable estimate of the lost data,
based upon no more than three (3) to twelve (12) consecutive months of prior usage data.
16.0 Billing Arrangements for LEC Carried IntraLATA Toll
16.1 For LEC Carried IntraLATA Toll each Party will deliver monthly settlement statements for terminating the
other Party's IntraLATA Toll traffic based on a mutually agreed schedule as described in this Section:
16.2 Until such time when SBC Texas offers to bill IntraLATA Toll Traffic using terminating records, the Parties
will use the Category 92 method of data exchange. Once the terminating records are offered by SBC
TEXAS, if CLEC does not have the technical ability to correctly generate bills from terminating recordings,
SBC TEXAS will continue to provide the appropriate Category 92 records to allow billing by the CLEC. The
decision by the CLEC to cease the exchange of Category 92 records with SBC TEXAS and replace it with
terminating recordings does not in any way relieve the obligation of the CLEC to exchange data with other
LECs
16.3 When applicable, the Parties will transmit the summarized originating minutes of use within 15 business
days following the prior month's close of business via the Category 92 record process to the terminating
Party for subsequent monthly intercompany settlement billing.
16.4 Bills rendered by either Party will be paid within 30 days of receipt subject to subsequent audit verification.
16.5 Detailed technical descriptions and requirements for the recording, record exchange and billing of traffic are
included in the Technical Exhibit Settlement Procedures (TESP), a copy of which has been provided to
CLEC by SBC TEXAS.
16.6 MOUs for the rates contained in this Attachment will be measured in seconds by call type, and accumulated
each billing period into one minute increments for billing purposes in accordance with industry rounding
standards.
