Initial Reports Narrative

Illinois: The Illinois Trial officially ended on June 1, 1999. Pooling within the Chicago-area NPAs is now considered as the standard number administration methodology for all LNP-capable service providers. Pooling within NPA 708 will be implemented after the Y2K “Quiet Period” (12/1 thru 3/1). The pooling administration guidelines currently in use are those developed in Illinois for the original trial. Although similar to the INC pooling guidelines, there are some differences, primarily in the areas of priorities for block assignment and format of the (application and confirmation) forms.

Pursuant to the ICC’s Order in 97-0192, released May 6. 1998, all carriers with numbering resources within the Chicago-area NPAs are obligated to:

1) Open only one thousands-block at a time within an assigned NXX and utilize 90% of numbers within before opening another thousands- block

2) Refrain from assigning numbers within a new NXX until 75% of numbers within existing NXXs (in the same rate area) have been utilized.

3) File quarterly reports of number utilization rates, by thousands-block.

Comparison of the projected NPA exhaust date at the start of pooling in area code 847 with the most recent projection suggests that number pooling may have extended the life of that NPA by 5 quarters. However, during the trial 18 full NXXs were returned to the Code Administrator, which could have added an additional 2-3 months’ supply of codes. The overall consumption of numbering resources appears to have increased within NPA 847, rising from an average 6.25 NXXs per month (see A3) to an equivalent 11.33 [(C13 + C19) /18]. To date, pooling within NPA 847 appears to have reduced the overall consumption of (equivalent) NXXs by 69% [100 -((C9 + C19)/18)/11.33].

Few, if any, conclusions can be drawn at this time from the pooling results in the other Chicago-area NPAs.

California: The pooling trial in the 310 NPA in California has been ordered but is not in place. Requests for utilization data from service providers indicate that the PUC may only include blocks with contamination rates of ten percent or less, but the Commission has been otherwise silent on this issue. The Commission is apparently counting heavily on pooling to conserve numbers since it has suspended other forms of relief at this time, including the previously planned issuance of an additional area code. The FCC ordered California to employ pooling by MSA, but the State is apparently using NPAs as its basis for pooling in spite of that Order. It is also important to note that as of January 5, 2000, NeuStar’s prediction of code exhaust (based on the most recent utilization and forecasting data provided by the industry) suggests that pooling will delay the exhaust of the 310 NPA by six months.

No other conservation methods employed.

CPUC selected an NPA that was already near exhaust which may have a negative impact on quantity of numbers available for donation to pool.

A successful pooling trial would conserve numbering resources.

Maine: Single NPA state. One NPA state, outside Top 100 MSAs.

Fill rate threshold of 75% prior to opening new blocks, codes; must be at 6 months to exhaust prior to opening new blocks, codes.

Pooling only in RBOC territory. (approximately 148 of 249 rate centers)

An appreciable extension of exhaust date.

Avoidance of new area codes being introduced.

New York: Other points to be tracked: The New York numbering task force agreed to build the initial 716 inventory with clean thousand blocks. If, after all participating carriers donate their clean blocks and more numbers are needed to meet the nine-month inventory, carriers will donate blocks with no more that 10% “contamination.” LNP-capable code holders are required, by the NY DPS, to follow “pre-implantation: guidelines until pools are established. In these guidelines LNP-capable code holders must: 1) administer their codes in blocks of thousand numbers on a rate center basis; 2) set aside (i.e., restrict from assignment in their telephone administration systems) all unopened thousand blocks currently assigned to them, unless no other numbers are available; 3) refrain from assigning numbers from any thousand block in an NXX with 100 or fewer numbers currently in use, unless no other numbers are available.

The NY DPS also ordered the use of wide area rate centers (WARC.) There is a special task force of industry participants studying the financial and technical impacts to such a application. A wide area rate center is defined, by the NYDPS as: “a single-LATA wide rate center for each area code whereby a carrier could use a single NXX code LATA-wide and thus would not need to have an NXX in every traditional rate center. The WARC, and all the NXX codes assigned to it, would be included in the local calling area for customers in every traditional rate center.”

-----------------------

[1] Exhaust projection assumed assignment of new NPA relief code. Since the CPUC has placed a hold on implementing the new code, the exhaust projection has been moved to 3Q2000.
