PSTN• PSTN, or the Public Switched

Telephone Network is the network of equipment, lines, and controls assembled to establish communication paths between calling and called parties in North America.

• Originally a network of fixed-line analog telephone systems, the PSTN is now almost entirely digital, and now includes mobile as well as fixed telephones.


8

VoIP• VoIP, or Voice over Internet

Protocol, is a means of using a digital network to make phone calls. The network can be either private or public, cable or wireless.

• Phone calls can be made to another computer with VoIP capability or to regular landline phones or cell phones.

• Utilizes packetized voice information in digital format using the Internet Protocol.

11

Selective Router• A telephone company

PSTN central switch that intelligently distributes calls to the PSAPs.

• These special switches look up the ESN associated with the ANI and routes the 9-1-1 call to the PSAP that the ESN is associated with.


12

ANI Automatic Number Identification (ANI) is a feature of a telephone network that permits the display or capture the telephone numbers of the access line from which a call originates.

ELT ELT (English Language Translation) is an alphanumeric description of the primary Law Enforcement, Fire and Emergency Medical Service agencies associated with a given Emergency Services Zone/Number.

Includes the name of the first-responder agency, and may include their station number (for dispatch purposes) and telephone number.

ESZ / ESN• The ESZ (Emergency Service

Zone) is a geographic region which is associated with unique emergency responders (Police, Fire, EMS), and each ESZ is assigned a 3 to 5 digit ESN (Emergency Service Number).

• A PSAP may have multiple ESNs associated with it, but ESNs will only be associated with a single PSAP.

• The ESN serves two functions. It is used to update the 9-1-1 selective router with the correct routing information and is used to associate English Language Translation (ELT) to the record in the ALI database.

ESN 260


16

I-1 VoIP Solution• In the I-1 solution, the location of the

caller simply is not automatically conveyed to the PSAP.

• In many I-1 solutions, the VoIP service provider does not have a direct 9-1-1 connection to the PSAP. Instead, when an individual dials 9-1-1, the call is routed to a dedicated ten digit administrative lineat the PSAP.

• Could also result from a transfer from another agency over a ten digit administrative line at the PSAP.


17

I-2 VoIP Solution• In the I-2 solution, a VoIP 9-1-1

call is routed over the PSAP 9-1-1 trunks and directly to the emergency operators at the PSAP. The location of the caller is provided to the PSAP in the ALI response.

• Where the service is nomadic, an ALI solution could look like the 9-1-1 solution for wireless phones, where a latitude and longitude is given.


18

I-3 VoIP Solution• The I-3 solution is a pure IP solution.

Instead of going through the PSTN 9-1-1 trunks, the VoIP 9-1-1 call would be routed over an IP network (ESNet) to the PSAP.

• More useful information could be delivered both to the operator and then to the first responder.

• Unlike legacy PSAPs that are hard wired into the network and cannot move, if it is necessary to move an I-3 solution PSAP, the new IP location of the PSAP would be announced to the network and new IP calls could efficiently be routed to the new location.

VoIP 101 : Operational IssuesVoIP 101 : Operational Issues


34

Operational Issues• Call Audio May Not

Contain All Sounds –Background sounds may be distorted

• Caller’s Location May Not Be Accurate –Caller is Nomadic

• Caller’s Location May Be Outside the PSAP’s Normal Coverage Area –International Caller

• Dispatcher May Need To Ask Caller To Repeat Information and Identify Unusual Sounds.

• Dispatcher Should Always Confirm ALI Information.

• Dispatcher needs access to PSAP Registry, 24-hour VoIP Operational Center Contact Lines and Information Resources Including Routing to Foreign Countries.


35

Operational Issues• Call May Be From Non-

traditional VoIP Source –Telematics

• Non-traditional VoIP Source’s GIS Data May Not Be Current -Telematics

• Non-traditional VoIP Source May Be A Hearing / Speech Impaired Relay Center

• Dispatcher Should Confirm Critical Information

• Dispatcher Should be Prepared to Ask for and Plot Latitude and Longitude

• Dispatcher Should Be Provided SOP.


36

Operational Issues• Emergency Calls On

Ten Digit Lines May Be a Spoof Caller

• The Call’s ELT May Not Specify Responding Agencies

• Dispatcher Should Confirm Critical Information and Listen For Inconsistent Information

• Dispatcher Should have ESZ Information Available
