California PUC Approves 669 Overlay to 408 San Jose CA Metro Area [telecom]

Today, Thursday 20-October-2011, the California Public Utilities Commission (re)approved the telco industry's (re)submitted petition for an overlay to the 408 area code region in the San Jose CA Metro area. The new overlay NPA code is 669.

The docket number for the 2011 re-submission is A.11-06-008.

The 669 area code _WAS_ originally intended to overlay 408 over ten years ago, around 1999/2000, but implementation of the overlay at that time was subsequently "suspended" by the California PUC pending further studies regarding area code exhaust and stricter numbering and code conservation measures being developed by the industry and regulatory, i.e., thousands-block assignments within NXX

The ORIGINALLY intended implementation dates for the 408/669 NPA overlay WERE as follows:

[1+]ten-digit dialing (officially) permissive on Friday 01-January-1999 [1+]ten-digit dialing MANDATORY on Friday 01-October-1999

Permissive intra-408 [1+]ten-digit dialing was probably in place several years prior to 1999, however.

But the California PUC "temporarily" halted further implementation of the 408/669 overlay (i.e., mandatory [1+]ten-digit intra-408 dialing), prior to the October 1999 date. And it later formally halted (until further notice), all "pending" overlays for the state (all of them had been previously approved by the CA-PUC).

I don't know if (at the time) Lockheed-Martin-IMS-CIS-NANPA ever announced a date when ILECs/CLECs/WSPs could begin requesting new

669-NXX, but the "effective" date of such would have been on Saturday 01-January-2000, the official "effective" date for the new 669 overlay NPA.

And there doesn't seem to have been any such "POTS" 669-NXX codes actually assigned by NANPA, although "special" 669-NXX did have an "effective" date put into the TRA/etc. databases at that time, such as 669-555, the 669-777 code for the test-number, Pacific Bell's NXX codes under the 669 NPA for time-of-day, high-volume mass calling, etc.

The test-number was to have been 669-777-0669, the 669-777 code working out of Pacific Bell's SNJSCA11DS0, a Lucent-WECO 5ESS associated with the San Jose: North-DA ratecenter. The effective date was to have been Saturday 20-November-1999, and the disconnect date would have been. Saturday 20-May-2000. I don't think that Pacific Bell ever started up a test-announcement on 669-777-0669, however some IXC/LD-carriers did open up 669-777 in their routings/ translations as a "valid" NPA-NXX code. I can remember going to a Pacific Bell "vacant code recording" when dialing 669-777-xxxx (including -0669) via AT&T-LL, MCI, (US)Sprint, and other IXCs.

LM-IMS-CIS-NANPA (Lockheed-Martin) did issue Planning Letter #149, dated 25-January-1999, announcing the 408/669 overlay in 1999/2000.

(NANPA, the North American Numbering Plan Administration was AT&T until 1984 divestiture, then it was turned over to the new and spun out of the old Bell System "Bellcore" entity. Lockheed-Martin took over the NANPA function with January 1998, a little over a year before Bellcore was renamed Telcordia. In January 2000, LM turned over NANPA to Warburg-Pincus' as "NeuStar".)

A subsequent "generic" PL-206 was issued on 14-January-2000 (a year later) announcing that ALL pending California overlays had been (temporarily) halted by the CA-PUC, until further notice.

There were _NO_ new area codes implemented for California, neither pending splits nor pending overlays, following the 619/858 split for the northern San Diego CA suburbs in Summer/Fall 1999, until the

909/951 split in the San Bernardino/Riverside area during Summer/Fall 2004.

And then later new NPAs in California starting in 2006, were overlays, most of them having been previously "halted" overlays, and a couple of previously "halted" splits which were changed to overlays.

NeuStar-NANPA and the telco industry are re-submitting to the CA-PUC, requests for overlays, one-by-one "as needed", and reactivation of the

408/669 overlay relief is one of them.

And the industry (through NeuStar-NANPA) has (re)submitted the request to overlay 408 with 669, to the California PUC; the CA-PUC has (re)approved NANPA's filing for a 408/669 overlay, today Thursday

20-October-2011, the 408/669 overlay having been "on hold" since 1999/2000 when it was originally planned to take effect.

Implementation dates "this time around" are still to be determined by the telco industry with approval from the CA-PUC, and announced by NeuStar-NANPA and the CA-PUC, in a forthcoming NANPA Planning Letter to be issued possibly during the next several weeks.

A "formal" six-month period of permissive [1+]ten-digit dialing alongside existing seven-digit dialing within 408 will take place, and then mandatory [1+]ten-digit dialing will take place about a month before the first new (pre)assigned (POTS) 669-NXX codes could first begin to take effect. Note that such permissive intra-408 [1+]ten-digit dialing has been in effect throughout most-if-not-all of California for probably twenty years now (and maybe even longer in some places), but there will still be a "formal, announced" period of permissive [1+]ten-digit dialing alongside existing seven-digit dialing prior to the actual overlay.

It is LIKELY (though not yet formally determined) that the effective date of potential new 669-NXX could be in November 2012 (a year from now), with mandatory [1+]ten-digit intra-408 dialing being at some point in October 2012.

The test-number this time is likely to be 669-669-1669, which is the format that at&t-ILEC has mostly been using for area code test-numbers which they provide in their ILEC territory. Pacific Bell was taken over by SBC in the late 1990s, and in 2005, SBC bought AT&T-LL/etc., and renamed everything as "at&t".

I don't know for certain which switch/CLLI is going to provide the test-number this time, but I assume that it will still be provided out of at&t/SBC/Pacific Bell's SNJSCA11DS0 Lucent-WECO 5ESS, associated with the San Jose: North-DA ratecenter, which is the switch that provided the test-number on the first attempt to implement the overlay ten-plus years ago.

The 408/669 NPA region includes eleven (11) ratecenters, all are within at&t/SBC/Pacific Bell's LATA #722 "San Francisco CA Metro", and are associated with the following landline incumbent telcos.

(NOTE that there ARE some wireless 408-NXX codes in the Monterey LATA which did NOT change/split to NPA 831 in 1998)

(there are also six at&t/SBC/Pacific*Bell ratecenters of the San Francisco/etc CA LATA #722 in the 831 NPA to the south; AND ratecenters in LATA #722 of Pacific*Bell (and GTE, GTE/Contel, Frontier/Citizens) in NPAs: 415/(628), 510/(341), 650/(764), 925, 707)
