2.0 Additional Terms For Provisioning

2.1.1 SBC TEXAS shall provide all provisioning services to CLEC during the same business hours SBC TEXAS
provisions similar services for its end user customers but at a minimum Monday-Friday, 8:00 a.m. to 5:00
p.m., excluding Holidays and where an accessible letter has notified CLEC of a central office freeze. SBC
TEXAS will provision non-coordinated standalone number portability-only cutovers on Saturdays, 8:00 a.m.
to 5:00 p.m. and on Sundays from 8:00 a.m. to 5:00 p.m., except during hours on Sundays when the
Regional Service Management System (RSMS) is unavailable due to update or maintenance activity.
Provisioning of non-coordinated standalone number portability cutovers on Sundays is subject to CLEC
obtaining industry agreement that all carriers will conduct their Local Service Management Systems (LSMS)
update or maintenance activity on Sundays during the same maintenance window as the RSMS. Recurring
charges for Sunday provisioning of non-coordinated standalone number portability cutovers will be
determined via the Bona Fide Request process and CLEC agrees to reimburse SBC TEXAS for reasonable
costs incurred in developing the capability for Sunday provisioning of non-coordinated standalone LNP
cutovers, as provided in the applicable Bona Fide Request process. Such charges shall be paid, and
reimbursed when applicable, as provided in the Bona Fide Request process. If CLEC requests that SBC
TEXAS perform provisioning services or complete service requests at times or on days other than as
required in the preceding sentences, SBC TEXAS shall provide such services at the rates, if any, as
provided in the Bona Fide Request process.
2.1.2 When an end user changes from one Party to the other Party and does not retain its original telephone
number, the Party formerly providing service to the end user will provide a referral announcement on the
abandoned telephone number, however in circumstances where a resale or UNE-P customer disconnects
service, SBC shall provide the referral announcement. These arrangements will be provided for the same
period of time and under the same terms and conditions as such Party provides such arrangements to its
existing end users, but must be requested on the LSR. Custom messages, extensions in duration, or other
special requests are subject to each Party’s applicable tariffs.
