                    CHAPTER I--FEDERAL COMMUNICATIONS

                         COMMISSION (CONTINUED)

 

PART 20_COMMERCIAL MOBILE RADIO SERVICES--Table of Contents

 

Sec. 20.18  911 Service.



    (a) Scope of section. The following requirements are only applicable 

to Broadband Personal Communications Services (part 24, subpart E of 

this chapter), Cellular Radio Telephone Service (part 22, subpart H of 

this chapter), and Geographic Area Specialized Mobile Radio Services and 

Incumbent Wide Area SMR Licensees in the 800 MHz and 900 MHz bands 

(included in part 90, subpart S of this chapter) and those entities that 

offer voice service to consumers by purchasing airtime or capacity at 

wholesale rates from these licensees, collectively CMRS providers. In 

addition, service providers in these enumerated services are subject to 

the following requirements solely to the extent that they offer real-

time, two way switched voice service that is interconnected with the 

public switched network and utilize an in-network switching facility 

which enables the provider to reuse frequencies and accomplish seamless 

hand-offs of subscriber calls.

    (b) Basic 911 Service. CMRS providers subject to this section must 

transmit all wireless 911 calls without respect to their call validation 

process to a Public Safety Answering Point, or, where no Public Safety 

Answering Point has been designated, to a designated statewide default 

answering point or appropriate local emergency authority pursuant to 

Sec. 64.3001 of this chapter, provided that ``all wireless 911 calls'' 

is defined as ``any call initiated by a wireless user dialing 911 on a 

phone using a compliant radio frequency protocol of the serving 

carrier.''

    (c) TTY Access to 911 Services. CMRS providers subject to this 

section must be capable of transmitting 911 calls from individuals with 

speech or hearing disabilities through means other than mobile radio 

handsets, e.g., through the use of Text Telephone Devices (TTY).

    (d) Phase I enhanced 911 services. (1) As of April 1, 1998, or 

within six months of a request by the designated Public Safety Answering 

Point as set forth in paragraph (j) of this section, whichever is later, 

licensees subject to this section must provide the telephone number of 

the originator of a 911 call and the location of the cell site or base 

station receiving a 911 call from any mobile handset accessing their 

systems to the designated Public Safety Answering Point through the use 

of ANI and Pseudo-ANI.

    (2) When the directory number of the handset used to originate a 911 

call is not available to the serving carrier, such carrier's obligations 

under the paragraph (d)(1) of this section extend only to delivering 911 

calls and available call party information, including that prescribed in 

paragraph (l) of this section, to the designated Public Safety Answering 

Point.



    Note to paragraph (d): With respect to 911 calls accessing their 

systems through the use of TTYs, licensees subject to this section must 

comply with the requirements in paragraphs (d)(1) and (d)(2) of this 

section, as to calls made using a digital wireless system, as of October 

1, 1998.



    (e) Phase II enhanced 911 service. Licensees subject to this section 

must provide to the designated Public Safety Answering Point Phase II 

enhanced 911 service, i.e., the location of all 911 calls by longitude 

and latitude in conformance with Phase II accuracy requirements (see 

paragraph (h) of this section).

    (f) Phase-in for network-based location technologies. Licensees 

subject to this section who employ a network-based location technology 

shall provide Phase II 911 enhanced service to at least 50 percent of 

their coverage area or 50 percent of their population beginning October 

1, 2001, or within 6 months of a PSAP request, whichever is later; and 

to 100 percent of their coverage area or 100 percent of their population 

within 18 months of such a request or by October 1, 2002, whichever is 

later.

    (g) Phase-in for handset-based location technologies. Licensees 

subject to this section who employ a handset-based location technology 

may phase in deployment of Phase II enhanced 911 service, subject to the 

following requirements:

    (1) Without respect to any PSAP request for deployment of Phase II 

911 enhanced service, the licensee shall:

    (i) Begin selling and activating location-capable handsets no later 

than October 1, 2001;



[[Page 17]]



    (ii) Ensure that at least 25 percent of all new handsets activated 

are location-capable no later than December 31, 2001;

    (iii) Ensure that at least 50 percent of all new handsets activated 

are location-capable no later than June 30, 2002; and

    (iv) Ensure that 100 percent of all new digital handsets activated 

are location-capable no later than December 31, 2002, and thereafter.

    (v) By December 31, 2005, achieve 95 percent penetration of 

location-capable handsets among its subscribers.

    (vi) Licensees that meet the enhanced 911 compliance obligations 

through GPS-enabled handsets and have commercial agreements with 

resellers will not be required to include the resellers' handset counts 

in their compliance percentages.

    (2) Once a PSAP request is received, the licensee shall, in the area 

served by the PSAP, within six months or by October 1, 2001, whichever 

is later:

    (i) Install any hardware and/or software in the CMRS network and/or 

other fixed infrastructure, as needed, to enable the provision of Phase 

II enhanced 911 service; and

    (ii) Begin delivering Phase II enhanced 911 service to the PSAP.

    (3) For all 911 calls from portable or mobile phones that do not 

contain the hardware and/or software needed to enable the licensee to 

provide Phase II enhanced 911 service, the licensee shall, after a PSAP 

request is received, support, in the area served by the PSAP, Phase I 

location for 911 calls or other available best practice method of 

providing the location of the portable or mobile phone to the PSAP.

    (4) Licensees employing handset-based location technologies shall 

ensure that location-capable portable or mobile phones shall conform to 

industry interoperability standards designed to enable the location of 

such phones by multiple licensees.

    (h) Phase II accuracy. Licensees subject to this section shall 

comply with the following standards for Phase II location accuracy and 

reliability:

    (1) For network-based technologies: 100 meters for 67 percent of 

calls, 300 meters for 95 percent of calls;

    (2) For handset-based technologies: 50 meters for 67 percent of 

calls, 150 meters for 95 percent of calls.

    (3) For the remaining 5 percent of calls, location attempts must be 

made and a location estimate for each call must be provided to the 

appropriate PSAP.

    (i) Reports on Phase II plans. Licensees subject to this section 

shall report to the Commission their plans for implementing Phase II 

enhanced 911 service, including the location-determination technology 

they plan to employ and the procedure they intend to use to verify 

conformance with the Phase II accuracy requirements by November 9, 2000. 

Licensees are required to update these plans within thirty days of the 

adoption of any change. These reports and updates may be filed 

electronically in a manner to be designated by the Commission.

    (j) Conditions for enhanced 911 services. (1) Generally. The 

requirements set forth in paragraphs (d) through (h) of this section 

shall be applicable only if the administrator of the designated Public 

Safety Answering Point has requested the services required under those 

paragraphs and the Public Safety Answering Point is capable of receiving 

and utilizing the data elements associated with the service and a 

mechanism for recovering the Public Safety Answering Point's costs of 

the enhanced 911 service is in place.

    (2) Commencement of six-month period. (i) Except as provided in 

paragraph (ii) of this section, for purposes of commencing the six-month 

period for carrier implementation specified in paragraphs (d), (f) and 

(g) of this section, a PSAP will be deemed capable of receiving and 

utilizing the data elements associated with the service requested, if it 

can demonstrate that it has:

    (A) Ordered the necessary equipment and has commitments from 

suppliers to have it installed and operational within such six-month 

period; and

    (B) Made a timely request to the appropriate local exchange carrier 

for the necessary trunking, upgrades, and other facilities.

    (ii) For purposes of commencing the six-month period for carrier 

implementation specified in paragraphs (f) and (g) of this section, a 

PSAP that is



[[Page 18]]



Phase I-capable using a Non-Call Path Associated Signaling (NCAS) 

technology will be deemed capable of receiving and utilizing the data 

elements associated with Phase II service if it can demonstrate that it 

has made a timely request to the appropriate local exchange carrier for 

the ALI database upgrade necessary to receive the Phase II information.

    (3) Tolling of six-month period. Where a wireless carrier has served 

a written request for documentation on the PSAP within 15 days of 

receiving the PSAP's request for Phase I or Phase II enhanced 911 

service, and the PSAP fails to respond to such request within 15 days of 

such service, the six-month period for carrier implementation specified 

in paragraphs (d), (f), and (g) of this section will be tolled until the 

PSAP provides the carrier with such documentation.

    (4) Carrier certification regarding PSAP readiness issues. At the 

end of the six-month period for carrier implementation specified in 

paragraphs (d), (f) and (g) of this section, a wireless carrier that 

believes that the PSAP is not capable of receiving and utilizing the 

data elements associated with the service requested may file a 

certification with the Commission. Upon filing and service of such 

certification, the carrier may suspend further implementation efforts, 

except as provided in paragraph (j)(4)(x) of this section.

    (i) As a prerequisite to filing such certification, no later than 21 

days prior to such filing, the wireless carrier must notify the affected 

PSAP, in writing, of its intent to file such certification. Any response 

that the carrier receives from the PSAP must be included with the 

carrier's certification filing.

    (ii) The certification process shall be subject to the procedural 

requirements set forth in sections 1.45 and 1.47 of this chapter.

    (iii) The certification must be in the form of an affidavit signed 

by a director or officer of the carrier, documenting:

    (A) The basis for the carrier's determination that the PSAP will not 

be ready;

    (B) Each of the specific steps the carrier has taken to provide the 

E911 service requested;

    (C) The reasons why further implementation efforts cannot be made 

until the PSAP becomes capable of receiving and utilizing the data 

elements associated with the E911 service requested; and

    (D) The specific steps that remain to be completed by the wireless 

carrier and, to the extent known, the PSAP or other parties before the 

carrier can provide the E911 service requested.

    (iv) All affidavits must be correct. The carrier must ensure that 

its affidavit is correct, and the certifying director or officer has the 

duty to personally determine that the affidavit is correct.

    (v) A carrier may not engage in a practice of filing inadequate or 

incomplete certifications for the purpose of delaying its 

responsibilities.

    (vi) To be eligible to make a certification, the wireless carrier 

must have completed all necessary steps toward E911 implementation that 

are not dependent on PSAP readiness.

    (vii) A copy of the certification must be served on the PSAP in 

accordance with Sec. 1.47 of this chapter. The PSAP may challenge in 

writing the accuracy of the carrier's certification and shall serve a 

copy of such challenge on the carrier. See Sec. Sec. 1.45 and 1.47 and 

Sec. Sec. 1.720 through 1.736 of this chapter.

    (viii) If a wireless carrier's certification is facially inadequate, 

the six-month implementation period specified in paragraphs (d), (f) and 

(g) of this section will not be suspended as provided for in paragraph 

(j)(4) of this section.

    (ix) If a wireless carrier's certification is inaccurate, the 

wireless carrier will be liable for noncompliance as if the 

certification had not been filed.

    (x) A carrier that files a certification under paragraph (j)(4) of 

this section shall have 90 days from receipt of the PSAP's written 

notice that it is capable of receiving and utilizing the data elements 

associated with the service requested to provide such service in 

accordance with the requirements of paragraphs (d) through (h) of this 

section.



[[Page 19]]



    (5) Modification of deadlines by agreement. Nothing in this section 

shall prevent Public Safety Answering Points and carriers from 

establishing, by mutual consent, deadlines different from those imposed 

for carrier and PSAP compliance in paragraphs (d), (f), and (g)(2) of 

this section.

    (k) Dispatch service. A service provider covered by this section who 

offers dispatch service to customers may meet the requirements of this 

section with respect to customers who utilize dispatch service either by 

complying with the requirements set forth in paragraphs (b) through (e) 

of this section, or by routing the customer's emergency calls through a 

dispatcher. If the service provider chooses the latter alternative, it 

must make every reasonable effort to explicitly notify its current and 

potential dispatch customers and their users that they are not able to 

directly reach a PSAP by calling 911 and that, in the event of an 

emergency, the dispatcher should be contacted.

    (l) Non-service-initialized handsets. (1) Licensees subject to this 

section that donate a non-service-initialized handset for purposes of 

providing access to 911 services are required to:

    (i) Program each handset with 911 plus the decimal representation of 

the seven least significant digits of the Electronic Serial Number, 

International Mobile Equipment Identifier, or any other identifier 

unique to that handset;

    (ii) Affix to each handset a label which is designed to withstand 

the length of service expected for a non-service-initialized phone, and 

which notifies the user that the handset can only be used to dial 911, 

that the 911 operator will not be able to call the user back, and that 

the user should convey the exact location of the emergency as soon as 

possible; and

    (iii) Institute a public education program to provide the users of 

such handsets with information regarding the limitations of non-service-

initialized handsets.

    (2) Manufacturers of 911-only handsets that are manufactured on or 

after May 3, 2004, are required to:

    (i) Program each handset with 911 plus the decimal representation of 

the seven least significant digits of the Electronic Serial Number, 

International Mobile Equipment Identifier, or any other identifier 

unique to that handset;

    (ii) Affix to each handset a label which is designed to withstand 

the length of service expected for a non-service-initialized phone, and 

which notifies the user that the handset can only be used to dial 911, 

that the 911 operator will not be able to call the user back, and that 

the user should convey the exact location of the emergency as soon as 

possible; and

    (iii) Institute a public education program to provide the users of 

such handsets with information regarding the limitations of 911-only 

handsets.

    (3) Definitions. The following definitions apply for purposes of 

this paragraph.

    (i) Non-service-initialized handset. A handset for which there is no 

valid service contract with a provider of the services enumerated in 

paragraph (a) of this section.

    (ii) 911-only handset. A non-service-initialized handset that is 

manufactured with the capability of dialing 911 only and that cannot 

receive incoming calls.

    (m) Reseller obligation. (1) Beginning December 31, 2006, resellers 

have an obligation, independent of the underlying licensee, to provide 

access to basic and enhanced 911 service to the extent that the 

underlying licensee of the facilities the reseller uses to provide 

access to the public switched network complies with sections 20.18(d)-

(g).

    (2) Resellers have an independent obligation to ensure that all 

handsets or other devices offered to their customers for voice 

communications and sold after December 31, 2006 are capable of 

transmitting enhanced 911 information to the appropriate PSAP, in 

accordance with the accuracy requirements of section 20.18(i).
