By Advice Letter No. 28132 Filed, March 1, 2006.

_________________________________________________________________

SUMMARY

This Resolution approves the request of AT&T California (AT&T) to grandfather Number Retention Service (NRS). The grandfathering is reasonable because NRS was originally introduced for business customers to upgrade their service to Centrex or PBX with Direct Inward Dial (DID). Business customers were required to change their telephone numbers because the utility's central office switch serving the customer was not equipped for Centrex or PBX/DID service. Currently, all AT&T California switches are capable of providing both Centrex and PBX/DID service where the customer does not need to change their telephone number in order to upgrade service.

BACKGROUND

By Advice Letter (AL) 28132, filed March 1, 2006, AT&T requested authority to revise Schedule Cal. P.U.C. Nos. A1. Preliminary Statement, A5. Exchange Services, Table of Contents, 5.14 NRS and Cal. P.U.C. 175-T, Access Service, Section 18 Services for Resale in grandfathering NRS.

NRS allows business customers the option of retaining their existing number(s) when changing within or between grades of service if a number change is required. Calls made to the customer's retained number are forwarded to the customer's assigned number, which is transparent to the calling party.

Initially, NRS was introduced for business customers to upgrade their service to Centrex or PBX with DID. It requires the business customers to change their telephone numbers because the utility's central office switch serving the business customers was not equipped for Centrex or PBX/DID service. In today's technology, all AT&T's California switches are capable of providing both Centrex and PBX service, where the business customers will no longer need to change their telephone numbers to upgrade service.

Notice/Protests

AT&T indicates that copies of the AL were mailed to the interested utilities and/or parties. Notice of AL 28132 was published in the Commission's Daily Calendar on March 6, 2006. No protests to this AL were received.

DISCUSSION

AT&T's Cal P.U.C. No. A2.1.1, Rule 1 states;

"The term frozen/grandfathered service" applies to obsolete and/or outdated service the Utility no longer wishes to provide. The freezing/grandfathering of a service is the Utility's method of managing a tariff for this service prior to ultimately discontinuing the service or change existing tariff regulations without discontinuing certain rights, privileges or conditions of the service to existing customers."

By grandfathering NRS, the existing customers will continue to receive the service, subject to the terms and conditions of the service, but the service will not be available to new customers after the effective date of this Commission's Resolution T-17018. If the existing customers, subscribing to the service moves or discontinues the service, then this offering will no longer be available. Currently, there are 1,260 business subscribers to the NRS.

This AL filing will not increase any rate or charge, cause withdrawal of service, nor conflict with other schedules or rules.

Telecommunications Division, (TD) recommends approving AT&T's request to grandfather Number Retention Service because the current technology allows AT&T to upgrade the business customer classes of service and provide customers with the same telephone number in all of its switches. As a result, other services are now available to upgrade service and retain the customer's existing telephone number.

Commission approval of TD is based on the specifics of this AL and its associated tariff sheets and does not establish a precedent for the contents of future filing or for Commission approval of similar requests.

This is an uncontested matter in which the resolution grants the relief requested.

Accordingly, pursuant to PU Code 311 (g) (2), the otherwise applicable 30-day period for public review and comment is being waived.
