31-002 Code Vt. R. 31-010-002-X
The Vermont Enhanced 9-1-1 Board was created in 1994 by Act 197 (30 V.S.A.). The Board is responsible for the design and implementation of a reliable and efficient statewide enhanced 9-1-1 emergency calling service, which automatically routes the call to the appropriate answering location and which subsequently provides a display of a caller's telephone number and location. The 1994 Legislature determined that enhanced 9-1-1 would further the safety, health, and welfare of the state's citizens.
This document contains technical and operational standards prepared by the Enhanced 9-1-1 Board as required under 30 V.S.A.. These standards are firmly based on national enhanced 9-1-1 standards and are designed to assist in the development and operation of a reliable, uniform statewide enhanced 9-1-1 system. The Board may modify and update these standards as needed to take advantage of changes in technology during planning and later as identified during the operation of the system. Any changes and modifications of standards shall supersede those previously promulgated.
| INTRODUCTION |
The concept of a nationwide emergency telephone number was first adopted in Great Britain in 1937. Since then, other countries in Europe and elsewhere have employed a three-digit uniform emergency number. In the United States, President Johnson's Commission on Law Enforcement and Administration of Criminal Justice recommended a nationally uniform three-digit number in 1967 and a year later, AT&T announced it had reserved the numbers 9-1-1 for emergency use nationwide.
In 1992, the Vermont Department of Public Service (DPS), in response to concerns raised by consumers, emergency service providers, and Legislators, initiated a study of 9-1-1. In 1993, the Vermont Legislature passed Act 83, which provided funding and direction to the DPS for further analysis and study. In 1994, S.311, a law enabling implementation of statewide enhanced 9-1-1, was passed by the Vermont Legislature and signed by the Governor (Act 197, or 30 V.S.A.).
The Legislature determined that a single, statewide emergency number providing access to Public Safety Answering Points (PSAPs), and capable of mobilizing a broad range of lifesaving services, would result in faster, more coordinated and efficient emergency response.
Key to implementing effective enhanced 9-1-1 service is ensuring direct access from the caller to the authority having responsibility for mobilizing the broadest possible range of emergency interventions.
In Vermont, the responsibility and authority for delivering emergency medical services, fire protection, and law enforcement generally rests with municipalities. This is true even when supplemental services are performed by others, such as private ambulance companies or independent public authorities and non-profit organizations with limited internal fire protection and security forces.
Vermont's citizens and visitors deserve the highest uniform standard of public safety available. The existence of a statewide standard takes advantage of the economies of scale inherent in consolidating and coordinating government response to emergencies and helps maximize the use of public resources while setting the stage for better service. This standard embodies the best nationally-accepted philosophies, concepts and operating practices and is the result of the experience and latest thinking of many who have traveled this route before us.

The telephone companies shall identify all costs associated with modifying, upgrading and programming central offices that have been allocated to the 9-1-1 funding structure. The telephone companies shall explain the method and reason for any and all such allocations. Enhanced 9-1-1 modifications in central offices should be coordinated with general central office upgrades where practical and where such coordination does not significantly delay implementation.
The telephone companies shall also provide to the Board, on an annual basis, the current schedules for upgrading central offices.
In scheduling central office equipment upgrades and dial with dial replacements, telephone companies shall:
The current Remote-Host umbilical network in Vermont may introduce a single point of failure in the proposed enhanced 9-1-1 network. Loss of umbilical connectivity to a host switch will isolate subscribers in the remote exchange from the enhanced 9-1-1 network and normal calling would be restricted to the exchange boundaries. Additionally, a PSAP served by a Remote Switch that experiences loss of communications its HOST switch will encounter isolation from the enhanced 9-1-1 network.
The telephone companies shall work with the Board and system provider to identify vulnerabilities, determine restorative alternatives and provide to the Board a disaster recovery contingency plan which includes strategies and procedures designed to mitigate the isolation of remote switch exchanges. In host-remote telephone central office arrangements, the telephone company shall, where feasible, provide emergency re-route solutions for any potential central office failure utilizing land line and wireless technologies.
Provisions in the network shall ensure that only calls in which all three digits (9-1-1) are dialed, shall enter the 9-1-1 system. The network shall also prevent larger dialing sequences which contain the digits 9-1-1, from entering the 9-1-1 system.
The telephone company shall allow for access to 9-1-1 from intrastate foreign exchanges and contiguous inter-state foreign exchanges in states providing enhanced 9-1-1. The telephone company shall also allow for access to 9-1-1 from intrastate out WATS telephone service providers. Calls placed to 9-1-1 should be routed to the PSAP serving the area in which the facility (i.e., business) is located.
The 9-1-1 system shall be engineered to allow for forced disconnect of 9-1-1 calls placed to all levels of PSAPs. This will prevent blockage of 9-1-1 lines.
Each telephone company and Customer Owned Coin Operated Telephone (COCOT) system provider in the state shall convert each public or private coin or coinless telephone to dial tone first capability to allow 9-1-1 calls to be made without first inserting a coin or paying any other charge. Each provider of public or private coin or coinless telephones shall provide access to the enhanced 9-1-1 PSAP serving the geographic location of the coin phone, and prominently display instructions on how to use the service. Conversion of said telephone shall be made prior to cut over in the community where the instrument is located.
End Office Trunks
Trunk groups dedicated to enhanced 9-1-1 traffic are required from all Local Exchange and Competitive Access Providers' host or stand alone switches to designated enhanced 9-1-1 tandem switch(es). Trunk quantities shall be based on a P.01 grade of service with a minimum of two trunks from each switch. (P.01 grade of service stipulates not more than one 9-1-1 call in 100 calls will experience a busy signal during the Average Busy Season and Time Consistent Busy Hour). Initial end office trunking quantities shall reflect 1 Call Hundred Seconds (CHS) per 1000 main stations served as specified in documentation entitled Network Trunk Forecasting and Serving Guidelines for Enhanced 9-1-1 Service issued by ATT. Translations in each end office shall be programmed that all enhanced 9-1-1 traffic be routed to a designated primary enhanced 9-1-1 tandem switch. In the event 9-1-1 calls could not be completed to this switch, the end office would seamlessly advance 9-1-1 traffic to a designated secondary enhanced 9-1-1 tandem switch or other trunk group or number for call completion.
The system provider shall submit network performance reports to the Board monthly. These reports shall include the percentage of calls blocked for each four week period, during the average busiest hour for each tandem area, and shall specify the percentage of calls blocked from the end office to the tandem and the tandem to the PSAP.
Traditional PSAP equipment technology consists of an ANI/ALI retrieval system and analog attendant answering position key and trunk equipment. ANI information is routed to the appropriate PSAP over dedicated analog multifrequency trunk groups from the enhanced 9-1-1 tandem switch via the PSAP's serving central office.
The system provider in cooperation with the PSAPs and Secondary PSAPs shall conduct a telephone traffic study of all existing basic 9-1-1 and seven-digit emergency numbers to assist in determining the proper amount of enhanced 9-1-1 trunks. The system provider shall also be responsible for designing the network of the 9-1-1 systems to ensure that the systems are adequately trunked in order to achieve a minimum P.01 grade of service on an incoming and transfer basis.
There shall be a minimum of 1.5 dedicated trunks provisioned for each attendant position at the PSAP location.
Each PSAP shall also have at least two outdial non-published telephone lines to allow for administrative purposes associated with the 9-1-1 system.
Advances in digital technology, coupled with the deployment of ISDN central office elements have allowed the evolution of traditional analog PSAP customer premise equipment to an ISDN platform. While ubiquitous ISDN deployment has yet to be achieved, certain Central Office switches possess the capability of furnishing ISDN connectivity to a PSAP. Call set-up and completion time utilizing ISDN technology is substantially less than an analog system.
There shall be a minimum of one Basic Rate Interface (BRI) line provided for each answering position at a PSAP when served by ISDN technology.
The system provider shall ensure that the routing of 9-1-1 calls through the network and ALI information through the data link network shall be diversified as much as possible.
The system provider in cooperation with the PSAPs shall also design the 9-1-1 network to allow for default and alternate routing capabilities.
The transfer of 9-1-1 calls from a Primary PSAP to any Secondary PSAP or Ringing PSAP shall be accomplished through a dedicated or switched network.
The system provider shall provide data links to allow for the transfer of ANI and ALI data from the Primary PSAP to Secondary and Limited Secondary PSAPs. All data communication lines to and from a Primary PSAP shall operate at the highest speed possible to ensure timely delivery of this critical information.
The system provider shall also design the network and install customer premises equipment that will allow the PSAP to transfer a 9-1-1 Call and disengage from the conversation without disconnecting the 9-1-1 Caller.
Each emergency service provider shall maintain at least one published 7-digit or 10-digit emergency number.
To provide emergency maintenance coverage outside of normal business hours, the service provider may forward the statewide system toll free access number to a centralized location staffed with personnel trained to provide the same level of maintenance detailed in these Standards.
To prevent the widespread loss of enhanced 9-1-1 service, the system provider shall work toward eliminating any single point of failure that could compromise the reliability of the network. The system provider shall endeavor to maintain enhanced 9-1-1 network integrity, minimize the probability of system degradation and failure, and minimize the negative effects of degradation or failure should it occur. The system provider shall be attentive to costs in fulfilling these goals and shall provide cost data to the Board where there are alternative means for accomplishing these goals.
Network design concerns include, but are not limited to:
One year from Board approval of the Standards, the system provider shall submit a plan to the Board to eliminate the potential for single point of failure design within the entire enhanced 9-1-1 network. This plan is not intended to provide a duplicate network for each PSAP but rather to address eliminating any single point of failure which could result in a widespread loss of enhanced 9-1-1 service. In its plan, the system provider shall, to the greatest extent possible, review and reference the most technologically advanced practices of all the other network providers which have addressed or are addressing similar network protection concerns which improve the safety of the customers they serve.
The Board will submit the plan to the Public Service Department and Public Service Board (PSB) for review. Subsequent to the determination that the expenditures associated with implementing the plan are prudently incurred expenses, the system provider shall immediately begin to implement and complete the entire plan within two years.
The goal of the plan is to provide the greatest reliability for delivery of voice, data and TTY to all PSAPs throughout the State of Vermont.
The system provider shall develop or review and present to the Board by January 1st of each year, a contingency plan or changes to the plan which shall ensure network integrity to minimize the probability of system failure and provide continued emergency telecommunications service in the event of 9-1-1 service interruption. The plan shall include alternatives for the 9-1-1 service in areas such as central office, database center and tandem failures, overall redundancy of the 9-1-1 system, re-route plans and disaster recovery plans.
The PSAP shall devise a contingency plan to provide continued emergency service when the PSAP is out of service. The plan shall be submitted to the Board for approval and shall designate a potential alternate PSAP location. The plan shall include the PSAP's role as an alternate answering point, if applicable, and ensure that such answering points are accessible to TTY users.
A typical PSAP Disaster Recovery Contingency Plan (DRCP) shall consist of various sections which will be used by the local disaster recovery coordinators during local plan implementation, on-going upkeep, and activation. Components of the DRCP shall include but are not limited to the following:
Municipalities shall identify for its use, one of the board-approved default answering points which will receive 9-1-1 calls that are affected by ANI or Selective Routing failures.
Regulated Telecommunications Companies shall provide a list of contacts to the system provider and Board including employee coverage listings, supervisor listings and appropriate emergency personnel lists and contact numbers.

Regulated Telecommunications Companies shall provide ANI, Customer Name, ALI, Class of Service, (including Business, Coin, (identifying call-back capability), Residence, Foreign Exchange, Private Branch Exchange, Cellular, TTY), and any other information required by the Enhanced 9-1-1 Board, including updates at a frequency agreed upon in writing.
Regulated Telecommunications Companies shall comply with the requirements of 30 V.S.A. and these standards.
All municipalities that elect to participate in the enhanced 9-1-1 system shall work with the system provider to verify street names, number ranges, and emergency service zones (ESZ). A designated Municipal Contact and the system provider shall ensure that changes, deletions and additions to the Master Street Address Guide (MSAG) database should be made on an as occurred basis. Each city or town must review the MSAG yearly to ensure accuracy of the data and the emergency service zones.
Participating municipalities are encouraged to begin the development of the MSAG 12 to 18 months prior to the cut over of the 9-1-1 system. Municipalities and the system provider shall attempt to achieve at least a 98% accuracy rate with the 9-1-1 database.
After establishment of service, it is the municipalities' responsibility to continue to verify the accuracy of the routing information contained in the MSAG and to advise the system provider of any changes in the street names, establishment of new streets, changes in address numbers used on existing streets, closing and abandonment of streets, changes in police, fire, EMS or other appropriate agencies, jurisdiction over any address, annexations and other changes in municipal and county boundaries, incorporation of new communities or any other matter that will affect the routing of enhanced 9-1-1 calls to the proper PSAP.
The system provider shall make every reasonable effort to update Selective Routing and ALI data on a daily basis so that the number of records "not found" shall not exceed one percent of the total number of database lookups per quarter. Any records not updated within the 24 hour period shall be updated within three business days of receipt with the exception of records containing "special" fields which may require verification.
When updates to the ALI database are made, updates to the selective router shall be made at the same time.
The system provider shall submit reports of database performance to the Board on a quarterly basis. These reports shall include the total records updated for the Selective Routing and ALI databases during the quarter and provide a breakdown by the number of days required to complete each update. These reports shall also include detailed information on records "not found."

Each call taker shall fill out a trouble report when a call is found to have erroneous database information. The information shall be forwarded to the system provider in a format established by the system provider.
All provisions of enhanced 9-1-1 legislation in Chapter 87 of 30 V.S.A. are incorporated by reference.
All information aggregated for the purpose of building the ALI database is confidential and is exempt from disclosure under subchapter 3, chapter 5 of Title 1. These data shall not be used or released for any reason inconsistent with the intent of enhanced 9-1-1 law.
ANI and ALI information received at a PSAP as the result of a 9-1-1 call may be used in an incident report, and is subject to the exceptions and restrictions of Title 1, Chapter 5, Subchapter 3.
Once ANI and ALI information is released from the database as a result of a 9-1-1 call, it becomes part of the historical record of an incident and is no longer subject to the exclusive purview of the Enhanced 9-1-1 Board, rather it is subject to the exceptions and restrictions of existing regulations governing emergency service provider records (Title 1, Chapter 5, Subchapter 3).
The Board is not responsible nor liable for the use of data, collected by municipalities in the process of building the ALI database, by said municipalities.
ANI and ALI information received at a PSAP as the result of a 9-1-1 call may be imported into a CAD system via CAD interface in accordance with record-keeping procedures already in place.
At that point the information becomes part of the historical record of an incident and is no longer subject to the exclusive purview of the Enhanced 9-1-1 Board. Rather it is subject to the exceptions and restrictions of existing regulations governing emergency service provider records (Title 1, Chapter 5, Subchapter 3).
The Enhanced 9-1-1 Fund will provide a serial port or other appropriate means of transport at the PSAP equipment for interconnection to the CAD element while the call is processed. One-time and recurring costs associated with CAD interface are the responsibility of the public safety agency. CAD interface shall be specifically requested by the public safety agency, and the proposed interface product shall be subject to the review and approval of the Board before interconnection can occur.
The ALI shall be displayed immediately for all classes of service at the time the 9-1-1 call is presented to a position. The ALI shall include the following data:

The PSAP and public safety providers served by the PSAP shall review these procedures every six months for the first two years and then annually thereafter and make changes as needed.
All levels of Secondary PSAPs not operating on a 24-hour basis shall negotiate prior to cutover and in writing, call handling procedures with the designated Primary PSAP. Procedures shall be reviewed annually or on an as needed basis.
Each participating municipality shall establish, staff and operate on its own or with one or more municipalities, enhanced 9-1-1 Primary and/or Secondary PSAPs on a twenty-four hours a day, seven day a week, 365 days a year basis.
Many municipalities in Vermont contract for dispatching service with out-of-state agencies. These dispatch arrangements may continue. However, out-of-state dispatch centers do not qualify for funding from the Enhanced 9-1-1 Fund. They will function as dispatch points receiving 9-1-1 calls from a Primary or Secondary PSAP within Vermont by relay or transfer.
Each PSAP shall maintain at least one seven-digit emergency number to be published in the white pages of the telephone book as a back up to 9-1-1. This number shall also be used for receipt of incoming emergency calls transferred to the PSAP by other PSAPs for certain alternate and default routing arrangements.
Each Primary or Secondary PSAP shall establish personnel security clearance standards that are acceptable to all emergency service agencies served by the facility. Minimum PSAP site security shall consist of:
-- The PSAP shall designate a person as security officer.

Records of 9-1-1 call information, shall be retained for a period to be established by the Board.
No individual or company shall be allowed to send an automatic alarm or other alerting device that causes the digits "9-1-1" to be automatically dialed and transmits a prerecorded signal or message to the PSAP. Disabled persons who utilize special devices to request emergency assistance from agencies other than PSAPs may continue to do so.
Primary PSAPs shall give priority to the initial programming of fixed transfer and auto-dial transfer options for the transfer of 9-1-1 calls to Secondary PSAPs, Limited Secondary PSAPs, and Ringing PSAPs, as required for the dispatch of public safety services within the jurisdiction of the Primary PSAP.
Any fixed transfer and auto-dial transfer options available after initial programming shall be programmed to provide for call transfer capability to other Primary PSAPs in proximity to that PSAPs' jurisdiction. This capability shall allow the PSAP to utilize the dedicated/switched 9-1-1 network to transfer 9-1-1 calls pertaining to emergencies outside its jurisdiction, to the appropriate Primary PSAP.
Fixed transfer buttons shall only be programmable by the system provider. Primary PSAPs and the Relay Service, which links the deaf community with the hearing community for non-emergency service, shall be provided with a current list of seven-digit telephone numbers for every Primary PSAP in the state.
The list shall be used for the transfer of 9-1-1 calls or the relay of information regarding emergencies outside the Jurisdiction of the PSAP, when fixed transfer or auto-dial transfer options are not available.
The list shall be compiled by the Board with the assistance of the system provider and emergency service organizations. It shall be updated as changes occur and distributed by the Board as necessary. Emergency Service Agencies changing, adding, or deleting a seven-digit telephone number being used by a 9-1-1 system for emergency call information, shall submit this change in writing to the Board.
The Board or its designee may inspect each PSAP that utilizes enhanced 9-1-1 network features to determine if it meets the requirements of said PSAP standards and all other technical and operational standards required by law.
If an inspection reveals that the PSAP is not in compliance with the technical and operational standards, the Board will take appropriate action to cause the PSAP to come into compliance. Appropriate action may include routing the agency's 9-1-1 calls to an Alternate or Default PSAP until such time as the PSAP has remedied its failure to comply and demonstrated that henceforth it will comply with the Board's standards.
The system provider, in consultation with the Board, shall develop a uniform report to be submitted annually by each PSAP to the system provider and the Board. The report shall include, but not be limited to, the total number of calls and a numeric and statistical breakdown on the basis of call type, e.g., administrative, false, 9-1-1, emergency calls to 7-digit numbers, etc. It shall report the duration of each call. It shall report visitors to the PSAP site, and any other statistical information necessary to evaluate the performance of the PSAP and its personnel.
Communication personnel shall be trained and have the highest level of experience within available resources. Training should include, but is not limited to, the 9-1-1 Call Handling Procedures set forth in the Public Safety Answering Point Administration and Training Sections of the Vermont 9-1-1 Standards. Training materials shall be approved by the Board.
The system provider shall train a trainer of PSAP personnel. Regional training sessions shall be held on an on-going basis as determined by the Board. The purpose of this program will be to ensure that municipalities continue training after cutover on all components of the enhanced 9-1-1 system as outlined above in the Pre-Cutover section. The Board shall provide a lesson plan, and education and reference materials. The PSAP shall certify that each call-taker/dispatcher has received the training.
Each PSAP and Secondary PSAP shall establish procedures to handle calls from speech and hearing impaired individuals via TTY including the use of TTY call detectors and diverters where installed. Primary PSAPs and Secondary PSAPs shall test TTY equipment regularly and in compliance with the ADA.
All levels of PSAPs shall call back any unanswered or silent 9-1-1 call by obtaining the telephone number from the ANI display or printer. Agencies are required to develop call handling procedures and urged to dispatch a public safety response unit(s) if the PSAP receives no response to the call back.
All telephone company operators shall transfer Operator dialed emergency calls to the 9-1-1 trunks in the correct Primary PSAP territory. The ANI shall display a code identifying an operator assisted call to the PSAP. The telephone operator shall also announce to the PSAP an operator assisted call and provide the ANI.
Local enhanced 9-1-1 services are outside the scope of the Board's authority except when interconnection between a local enhanced 9-1-1 system and the state enhanced 9-1-1 system becomes necessary. In the case of interconnection the local enhanced 9-1-1 system will be held to the same standards as the state system.
Local enhanced 9-1-1 services that opt to be included in the state system to any extent are required to meet the technical and operational standards of the Board for enhanced 9-1-1 systems, and the requirements of 30 V.S.A.
Municipalities participating in the enhanced 9-1-1 system shall develop a public education program aimed at the emergency service needs of the community. The program should include a time line which provides educational materials prior to and on a continuing basis after out over of the 9-1-1 system.

Based on the non-English speaking population of a community, the Municipal Contact shall determine if 9-1-1 public education materials need to be developed in bilingual/secondary languages.
The digits "9-1-1" shall be the emergency number published inside the front cover of a phone book for municipalities participating in the enhanced 9-1-1 system. The advertisement of any emergency telephone number other than "9-1-1" is prohibited. "9-1-1" shall be the only published or advertised emergency number for those using TTY. The designation "9-1-1" shall only be used for emergency calls routed directly to a Primary PSAP.
Notwithstanding the above, municipalities are required to maintain one 7-digit emergency number for back-up purposes. That number may only be published inside the phone book with other municipal numbers.
Advertised use in Vermont of the designation "9-1-1" in connection with any commercial product or service could lead to public confusion and is strictly prohibited.
The digits "9-1-1" when displayed on emergency vehicles, signs, or other forms of advertisement shall be printed in plain block type numerals with a "dash" (-) appearing between each number. This will minimize any potential misinterpretation of the digits. The digits "9-1-1" shall be the only emergency number displayed on vehicles, signs or other legitimate forms of advertisement.
The system provider shall assist municipalities with the enhanced 9-1-1 public education program through the distribution of materials in the form of brochures, telephone stickers, and children's educational materials. 9-1-1 PSAPs shall be responsible for working with the system provider to ensure that an adequate campaign is maintained on a routine basis.
Publishers of telephone directories which contain emergency numbers shall annually publish the digits 9-1-1 as the official emergency number on the inside cover of the telephone book(s) for the municipalities participating in the Vermont enhanced 9-1-1 System.
