CO/NXX SubcommitteeIssue 545: Removal of Switch CLLI Information

from the NANPA Website

• Issue 545 Removal of Switch CLLI information from NANPA Website was accepted to address national security concerns documented in NRRIC Issue 0237: Removal of Unnecessary Switching Entity Information from Public Access; as well as other security-oriented governmental bodies

• Issue 545 directs the NANPA to remove Switch CLLI information from its Public Website; NANPA will continue to provide such information to authorized SPs and Regulators via the NANP Administration System (NAS)

• With FCC approval of NANPA Change Order 13, implementation was effective October 1, 2007.

LNPA SubcommitteeIssue 519: Pool Replenishment

• At the request of the PA and the NOWG, the INC explored options to ensure that the PA is able to maintain a “sufficient quantity of blocks available for assignment to satisfy the anticipated demand” while maintaining no more than a six-month inventory, per the Thousands-Block Pooling Contractor Technical Requirements document, section 2.14.1.

• A number of options, including forcing an SP to open a new code, were found to be either unenforceable or could have had negative impacts on end users.

• INC agreed that PAS should ask SPs via a pop-up box to take a portion of their requested blocks from the existing resources and the remaining blocks from a code opened for pool replenishment. This is intended to encourage SPs to share the burden of pool replenishment and discourage a single SP from taking all the remaining blocks in a pool.

• The Issue resolution results in changes to the Guidelines and a PA change order will be required.

INC VoIP SubcommitteeIssue 510: Internet-Based Relay Services

and Interoperability • The INC Issue is in response to a NANC Action Item:

“to take the lead in developing a technical response/recommendation regarding the . . . VRS [Video Relay Service] interoperability issue raised during the NANC meeting.”

• The NANC transcript defined the matter as follows:“In order for VRS to be functionally equivalent to voice telephone services, deaf and hard of hearing individuals, using video broadband communications, need uniform and static end-point numbers linked to the NANP that will remain consistent across all VRS providers, so that they can contact one another and be contacted to the same extent that PSTN and VoIP users are able to identify and call one another. . . [and] support dialing uniformity for VRS and point-to-point video users.”

• The INC report will focus on both the Number Assignment paradigm and the Number and Routing Database which will be required to support this functionality.

and Interoperability Video Relay Service (VRS)

VRS allows persons who are deaf or hard-of-hearing to communicate through the telephone system with hearing persons. The VRS caller, using a television or a computer with a video camera device or videophone and a broadband (high speed) Internet connection, contacts a VRS Communications Assistant (CA), who is a qualified sign language interpreter. They communicate with each other in sign language through a video link. The VRS CA then places a telephone call to the party the VRS user wishes to call. The VRS CA relays the conversation between the parties -- in sign language with the VRS user, and by voice with the called party. A voice telephone user can also initiate a VRS call by calling a VRS center, usually through a toll-free number.

and Interoperability Working Proposal

To maintain interoperability and help achieve functional equivalency for VRS, the INC likely will propose that:

• NANP numbers be assigned to deaf and hard of hearing relay users

• A Neutral Third Party Administered Central Database to support interoperability among relay providers by linking the relay user’s NANP number to the necessary Internet address

• The same approach be applied to other Internet-based relay services


8


and Interoperability Number Assignment Options

(Assignment to VRS Deaf or Hard-of-Hearing Relay Users)

• The INC is considering the following options for number assignments:

• VRS service providers obtain numbers from existing voice service providers and in turn assign them to VRS users.

• VRS service providers obtain numbers from a neutral third party and in turn assign them to VRS users.

• VRS users could obtain numbers directly from voice service providers and arrange for routing to their chosen VRS provider for incoming calls.

and Interoperability VRS Number and Routing Database - The INC is considering three major alternatives for

implementing a central database:

• Number Portability Administration Center (NPAC) – The NPAC is the entity that maintains the database of record for local number portability (LNP) in the United States and Canada. It has been proposed that the NPAC could also associate Universal Resource Identifiers (URIs) with deaf relay user telephone numbers so as to meet the database goals required for VRS calls.

• Dynamic DNS – Dynamic DNS (DDNS) is a standard capability used to link domain names to dynamic IP addresses. The deaf relay user’s equipment would provide its IP address to the DDNS Server where it would be associated with the relay user’s telephone number.

• DNS with Delegation to VRS Service Provider – This option is similar to DDNS, except the VRS user’s IP Address is held in a DNS server maintained by the called deaf relay user’s designated VRS provider. Standard DNS delegation procedures make the IP Address available to other VRS providers.

and Interoperability The INC Report: Status

• The draft report currently contains over 50 pages comprised of 7 sections and 4 appendices based on over 100 contributions towards the development of the report.

• The report is expected to contain a section that identifies components determined to be outside the scope of INC, but items that need to be considered in the overall design and implementation to achieve VRS Interoperability.

• The collective membership of the INC, including subject matter experts from the VRS Industry, has invested over 2,500 member/staff hours to date assembling and editing the VRS Interoperability Report.

• INC has been and will continue to meet twice a week until this report is finalized.

and Interoperability

Additional Points

• The INC believes the use of NANP resources will facilitate the provision of E911 service to relay users.

• The INC believes the Number and Routing Database should be operated by a Neutral Third Party with the appropriate Privacy & Security Considerations.

• The INC Report does not address how, or for which aspects of this service, Service Providers will be reimbursed by the TRS fund.
