1、 Tentative Interim Amendment NFPA 1221 Standard for the Installation, Maintenance, and Use of Emergency Services Communication Systems 2016 Edition Reference: 3.3.X (New), 8.6 (New), and new Corresponding Annex material TIA 16-1 (SC 15-8-24 / TIA Log #1171) Note: Text of the TIA was issued and incor
2、porated into the document prior to printing, therefore no separate publication is necessary. 1. Add new definitions and corresponding Annex A material to Section 3.3 as follows: 3.3.x* Automatic Location Identification (ALI). A series of data elements that informs the recipient of the location of th
3、e alarm. A.3.3.x. Automatic location identification is typically associated with an enhanced 9-1-1 telephone call. ALI can include the civic street address, building, floor, and room numbers and/or the latitude and longitude. 3.3.x* Automatic Number Identification (ANI). A series of alphanumeric cha
4、racters that informs the recipient of the source of the alarm. A.3.3.x. Automatic number identification is typically used in two disparate systems in emergency communications. First, ANI is a critical component of enhanced 9-1-1, where it identifies the device making the call to 9-1-1. Second, in tw
5、o-way radio communications, ANI can be associated with the radio device that is active on the voice communication channel. 3.3.x* Call Server. A system of electrical, mechanical, and computer components the function of which is to process incoming and outgoing telephone calls. A.3.3.x. Call server i
6、s a generic term for a centralized, computer applicationbased, telephone system. Call servers are the next generation of private branch exchange (PBX) systems. There are many advantages to using a call server over a legacy PBX, including the ability to add features via modification to the applicatio
7、n code and the ability to add extensions using either physical telephones or computer-based clients. 3.3.x* Multiple Line Telephone System (MLTS). A system designed to aggregate more than one incoming voice communication channel for use by more than one telephone. A.3.3.x The term multiple line tele
8、phone system refers to any solution, independent of the technology used, that allows an entity to use a group of voice communication channels from an exchange carrier to connect a multiplicity of end users for inbound, outbound, and intersystem telephone calls. An MLTS includes both PBX- and call se
9、rverbased solutions, including network-based and premises-based systems (e.g., Centrex, VoIP, as well as PBX, hybrid, and key telephone systems, as classified by the FCC under Part 68 requirements). 3.3.x* Private Branch Exchange (PBX). A system designed to connect to a local exchange carrier (incum
10、bent or competitive) to allow telephone calls to be distributed to extensions and extensions to use a set of voice communication channels to make outbound calls. A PBX also allows extensionto-extension telephone calls without connecting to the public switched telephone network. A.3.3.x. The PBX syst
11、em was first developed to allow a private entity to connect the telephone company to many users, breaking the one phone to one phone line ratio. Originally, this process was a manual one, in which a switch board operator would answer an incoming call and, using a physical patch cord, connect the inc
12、oming caller to the desired extension. When users wanted to make either an outbound or intersystem call, they first had to notify the switchboard operator and verbally explain their request. As technology progressed, switchboard operators were replaced first by mechanical devices that could interpre
13、t a rotary dial and later by dual tone multifrequency (DTMF) “Touch Tone”. 2. Add a new Section 8.6 and corresponding Annex A material as follows: 8.6 Multiple Line Telephone Systems (MLTS). 8.6.1* Every MLTS shall be designed to allow any extension to dial 9-1-1 without the need to dial any digit t
14、o obtain a dial tone. A.8.6.1. The MLTS must be programmed to allow a user to dial 9-1-1 without first having to dial 9 or any other number to reach the public switched telephone network. For example, 9-9-1-1 is not permissible. 8.6.2* The MLTS shall outpulse or signal the public switched telephone
15、network with a dialable telephone number that, when dialed, will reach the original 9-1-1 caller. A.8.6.2. The dialable number is used by the Public Safety Answering Point to call the 9-1-1 caller back in the event more information is needed or a call is dropped before sufficient information is obta
16、ined to initiate a dispatch. 8.6.3* The owner or entity responsible for the operation of the MLTS shall cause the location of the 9-1-1 caller to be made available to the public safety answering point telecommunicator in those jurisdictions where the enhanced 9-1-1 features ANI and ALI are available
17、 and in use. A.8.6.3. There are multiple methods to meet this requirement. Incumbent and competitive local exchange carriers offer private switch ALI, commonly known as PS/ALI services. PS/ALI allows the MLTS owner manage the location associated with the extensions telephone number. In addition, com
18、mercial services are available to both automate and act as an MLTS agent in providing and maintaining ALI for extensions that have both static and dynamic locations. 8.6.3.1* The ALI associated with the ANI of the MLTS extension shall be sufficient to direct a response to the 9-1-1 caller in an effi
19、cient manner and include, at a minimum, the civic address, building number, and floor, except as provided in 8.6.3.2. A.8.6.3.1. This matches the location granularity stated within the proposed model MLTS legislation in NENA 06-750 v3, “NENA Model Legislation E9-1-1 for Multi-Line Telephone Systems”
20、. 8.6.3.2* Paragraph 8.6.3.1 shall not apply to any MLTS serving a facility of less than 7000ft2. A.8.6.3.2 This matches the location granularity exception stated within the proposed model MLTS legislation in NENA 06-750 v3, “NENA Model Legislation E9-1-1 for Multi-Line Telephone Systems”.
