1.4 Overview
This document defines the
recommendations for the exchange of telephone number data with
a 9-1-1 Service Provider by companies participating in Service
Provider Local Number Portability. It anticipates the protection
of E9-1-1 data integrity, content, and call delivery regardless
of dial tone provider. It is the goal of these standards to support
current and future development consistent with the concept of
"One Nation, One Number". It is assumed that Federal,
State, or Local legislation will supersede these recommendations.
1.5 Reason for Reissue
NENA reserves the right to
modify this technical reference. Whenever it is reissued, the
reason(s) will be provided in this paragraph.
1.6 Acronyms/Terms
Acronym/Term Definition
Automatic Location An 9-1-1 Feature by which the name, address and responding
Identification (ALI) agencies
associated with the number of the telephone used to dial 9-1-1
is displayed at the PSAP at the time the call is answered.
Automatic Number The telephone number associated with the calling party.
Identification (ANI)
Company Identifier A NENA approved 3-5 character identity chosen by the Local

accessible data base, and is an entry item in NENA 02-001,
NENA Recommended Formats for Data Exchange.
Completion Date Applies to
the service order process date that does the physical disconnection
of dial tone by the donor company and the physical connection
of dial tone by the recipient company to an end user.
Data Exchange The NENA Data
Standards Subcommittee has established 2 versions of standard
data formats for use by data exchange partners when exchanging
E9-1-1 ALI data base information, referenced as NENA 02-001,
NENA Recommended Formats for Data Exchange.
Donor Company The Local Service
Provider responsible for the end user's telephone service and
E9-1-1 data prior to the migration of the telephone number to
the recipient company.
End User The 9-1-1 caller.
E9-1-1 Enhanced 9-1-1 (name,
address, and telephone number displayed).
1.6 Acronyms/Terms cont'd
Acronym/Term
Definition
Local Service Provider A term intended to encompass all companies providing dial tone
(LSP) to end users, including
but not limited to Incumbent Local Exchange Carriers (ILEC), Alternative
Local Exchange Carriers (ALEC) and Private Branch Exchange (PBX)
providers.
Migration The term used to
describe the inward transaction the recipient company submits
to the 9-1-1 Service Provider that signifies movement of telephone
service from a donor company.
National Emergency The National Emergency Number Association is a not-for-profit
Number Association corporation established in 1982 to further the goal of "One
(NENA) Nation-One Number."
NENA is a networking source and promotes research, planning and
training. NENA strives to educate, set standards and provide

number migrated from a different Local Service Provider.
Ported Out A Local Service Provider's term for the end user's telephone
Telephone Number number migrated
to a different Local Service Provider.
Recipient Company The new
Local Service Provider responsible for the end user's telephone
service and E9-1-1 data after the migration of the telephone number
from a donor company.
Relock The recipient company
will secure the record when the migration transaction replaces
the customer details and Company ID of the donor company. Also
allows the donor company to secure a telephone number record that
has been unlocked pending a migration to a different Local Service
Provider. (See Unlock)
Service Provider Allows the end user to retain their telephone number, providing
Local Number they remain within the same rate area or rate district (where
Portability (SPLNP) established),
when changing from one service provider to another.

9-1-1 Service Provider The
entity(ies) responsible for the ALI system data management (and/or
retrieval), and/or Selective Routing management, e.g., a Telephone

1.7 Reasons to Implement
and Benefits
Industry adoption of the standard will:

-Ensure reliable 9-1-1 call delivery
-Improve communications and remove barriers across entities
-Assist Local Service Providers toward compliance with the FCC order:
CC Docket 95-116,
complying with Local Number Portability
1.8 Implementation
How: Use of the standards
will provide the basis for agreements between the Local Service
Provider and the 9-1-1 service provider.
When: Should be completed
prior to the FCC mandated SPLNP conversion date schedule.

STANDARDS
2.6
The following edits for the C and D function codes in the NENA-02-001,
NENA Recommended Formats for Data Exchange for transactions
are in addition to any existing edits:
C -create error condition
if Company ID doesn't match between the embedded telephone number
record in the 9-1-1 data base and the update transaction.
D -create error condition
if Company ID doesn't match between the embedded telephone number
record in the 9-1-1 data base and the delete transaction.
STANDARDS cont'd
2.7
Create 2 additional function codes for NENA-02-001, NENA Recommended
Formats for Data Exchange to assure data integrity:
U
-Unlock telephone record transaction sent by the donor company.
This will make the telephone number available for the recipient
company to overwrite the embedded telephone number record. The
"U" function code requires a match of Company ID.
M
-Inward migration transaction sent by the recipient company.
This transaction requires an "unlocked" record in the
9-1-1 data base and will replace the customer information and
the Company ID on the "unlocked" record. The "M"
function code does not require a match of Company ID. If there
is not a record with the same telephone number in the 9-1-1 data
base the "M" transaction will be treated as an error
with a unique error code.
2.8 The 9-1-1 Service
Provider should make every effort where technically feasible to
minimize error reporting to the recipient company when an "M"
transaction is received before the corresponding "U"
transaction. The 9-1-1 Service Provider must notify the recipient
company whenever an "M" transaction is not successfully
processed. This can be done as part of the normal reporting process.
The 9-1-1 Service Provider
will reprocess all "M" transactions that did not successfully
process against an unlocked record, a minimum of one additional
time in one additional business day. "M" records to
be reprocessed will be treated as a warning with identification
of the donor company. If the final "M" attempt fails,
the transaction will be treated as an error.
2.9 The
service orders should be completed on the date (completion date)
the porting activities occur. It is recommended that upon order
completion, the "U" transaction will be sent by the
donor company and the "M" transaction will be sent by
the recipient company to the 9-1-1 Service Provider.
Create a unique informational
message code if an "M" transaction is processed and
the corresponding embedded data base record remains locked.
Create a unique error condition
code identifying when an "M" transaction reprocessing
fails in the attempt to update the 9-1-1 data base.
2.10
The 9-1-1 Service Provider must make an exception report(s) available
to the donor company if the embedded telephone number record has
been in an unlocked state for a period of time not less than 7
calendar days. Upon investigation, the donor company may relock
the embedded record using an "M" function code.
2.11 It
is expected that cooperative efforts occur between Local Service
Providers to resolve all error conditions in a timely manner.
