- ICC LNP R&B Meeting Minutes
A teleconference of the ICC LNP
R&B sub-committee was held on July 25 to
discuss issues of rating and billing impact.
Following is the status of each of the items
discussed on the teleconference.
descriptions of the Pre-Porting and
Port-on-Demand options of the Number Pooling
proposal were the primary topic of discussion. As
with our last teleconference, no issues were
identified as relevant to Rating and Billing
impact with either solution by the subcommittee.
However, two clarifications were requested by the
R&B Subcommittee based on Brents
description. These are two cons listed for the
Port-on-Demand proposal (Brent then referred me
to Barry Bishop, Chair - Operations Subcommittee,
who provided the responses below). Please call
Judy no later than close of business Wednesday,
July 30, if you still have concerns regarding
- Change for intra-SP port, need to
change SP network data table in NPAC which is
expensive, and limits flexibility in the future. Barry
Bishop has discussed this issue with Donna
Navickas and it is no longer believed to be a
concern by the Operations Subcommittee.
- Potential for rating
& billing problems if code holder is not
involved in the porting process. Our subcommittee
has requested that it be noted that this item did
not come from the R&B Subcommittee. Barry
cannot remember who raised this issue or how to
clarify it based on the original discussion in
his subcommittee, but agreed that given the
current NPAC/SMS porting procedures, it is
difficult to imagine that the code holder would
not be aware of the porting procedure. He
believes the Operations Subcommittee has dropped
this issue as well.
- Additionally, switch vendors
voiced issues that appeared to have switch
administration impact. They were asked to discuss
these issues with the Switch and Operations
Subcommittees so that their concerns could be
adequately addressed in the proper forum. An
Operations teleconference is scheduled Wednesday,
July 30 at 9:00 a.m. (CST). The dial-in number is
(312) 814-8097 for those interested in pursuing
New Chairperson for R&B
Judy is stepping down as chair
of the subcommittee. Anyone wishing to nominate
himself/herself for the position, please
contact Judy or Brent by close of business
Wednesday, July 30, and they will compile a
list of names and arrange for an
"election" in the near future.J
R&B Subcommittee Now Midwest Region R&B
The issue was raised at the
last Illinois Commerce Commission LNP Workshop
regarding officially making the R&B
Subcommittee a regional subcommittee, not just
specific to Illinois. The subcommittee approved
the recommendation and we are now supporting all
states in this regionIllinois, Indiana,
Michigan, Ohio, and Wisconsin. In the very near
future you will be hearing more about this issue.
We need to consider the other four states in our
region individually to insure that we understand
their unique state requirements and have made
appropriate recommendations to the service
providers in those states regarding new switch
features (such as the ones being developed for
California) or other upgrades to systems they may
need to deploy and implement LNP.J
Another meeting of the R&B
sub-committee is expected toward the end of
August. No date has been finalized at this time. J

LNP Workshop R&B Chair
Attachment B - Preliminary
Analysis Number Pooling Assumptions
Per Brian Baldwins 7/1/97 memo to chairs
of all Illinois sub-committees:
- What particular issues were discussed?
Potential impact of NXX-X pooling proposal on rating and
billing of ported calls.
- What assumptions were made?
- Our assumptions follow. Please
note: Assumptions 1-3 were provided by Brian in
his original June 3rd memo.
Assumptions 4-5 were developed during the June
R&B teleconference and Assumption #6 was
added during the July 15 teleconference.
- Sharing will be implemented at the
thousands-block level, among carriers serving the
same rate center or rate district as assigned the
- Shared NXXs will still be assigned
to a "home" switch and rate
- Thousands blocks within those NXXs
that are shared with other carriers will be
"ported" from the donor switch, using
the long-term LNP architecture.
- The ICC Rating and Billing
sub-committee does not anticipate any rating or
billing issues with the NXX-X pooling proposal
given the following additional assumptions:
- Geographic boundaries of rate
center/rate district are iron-clad, no
- Generation of the AMA (LRN) by the
switch does not deviate from the long-term LNP
- All NXXs used for number pooling
must be LNP-capable.
- What concerns were identified?
Concerns were the same as those of implementing LRN in
generalcarriers performing third-party
recording/billing services for other carriers may still,
in certain call scenarios, require modifications to their
back-office systems and/or new/modified interconnection
agreements to support the appropriate passing of billing
messages. The NXX-X pooling solution may exacerbate this
- What alternatives were looked at?
No alternative solutions were discussed. The R&B
sub-committee performed analysis only of the solution
requested based on the limited information presented in
the Baldwin June 3rd memo.
- What were the advantages/disadvantages
(e.g., costs, timing, etc.) of those alternatives?
Not applicable (see response to #5 above).
- What conclusions/recommendations were
As reported after the June R&B teleconference, the
sub-committee members have determined that the NXX-X
number pooling proposal should have no new technical
impact on deploying the LRN solution in Illinois based on
the above assumptions. However, the sub-committee
has asked (Brent Struthers) to see the current
documentation on this proposal to make a more definitive
analysis of this solution.
