8 1.0 INTRODUCTION 1.1 Purpose This document describes the interfaces between call answer centres and / or emergency response agencies and the TELUS Communications Inc. (TCI) network for the purpose of providing access to Provincial Service features to the agency s call takers. These interfaces allow dialled calls passed through TCI s network to terminate at the appropriate call answer centre. These interfaces also provide the emergency call taker with the pertinent calling number and location information of the caller. In Alberta the emergency call taker is also provided with call control features that enable the call taker to maintain control of the calling line. The interfaces between TCI s network and Local Service Providers network are outside of the scope of this document. 1.2 Service Description Provincial Service provides for the transport of all customer dialled calls to the appropriate municipal call answer centre, hereinafter referred to as a Public Safety Answering Point (PSAP), and between the PSAP and associated police, fire and ambulance dispatch centres. The municipalities and the various agencies are responsible for answering and responding to these emergency calls. The characteristics of the service are: o Universally recognized 3 - digit dialling (9 1 1) for connection to emergency response agencies serving the location of the caller. o High grade of service (P call in 1,000 may be blocked). o Special features to support the proficiency and effectiveness of answering attendants. In a typical operation the call is delivered to a PSAP where the attendant determines the nature of the emergency and forwards the call to the appropriate fire, police or ambulance dispatch centre. The PSAP attendant is supported by a number of special features that can facilitate targeted and accurate response. Provincial Service is associated with all primary exchange services. Local governments are responsible for the call answer and dispatch centres. 1.3 Feature Description Provincial Service, based on the NORTEL DMS-100 switch operating in conjunction with an adjunct computer running a TELUS developed software package, supports the following network based features: Selective Routing A central network database matches a caller s address to an Emergency Service June

9 Zone (ESZ). The ESZ represents municipal fire, police, and ambulance serving areas. This feature automatically routes an emergency call to the PSAP serving the caller based on the location of the caller Automatic Number Identification (ANI) The Selective Router outputs an ANI data record that identifies the telephone number of the caller. This information is sent to the ALI system where it can be processed to provide Automatic Location Identification (ALI) and a record of the call Automatic Location Identification (ALI) The network resident ALI System can display on the PSAP attendant s terminal the caller s name, address and telephone number. The ALI information is delivered from the network to the terminal in ASCII format. This information can assist in situations where the caller is unable to communicate with the attendant Enhanced Calling Party Hold Available in Alberta Only Enhanced Calling Party Hold (ECPH) ensures that people dialling the digits and hanging up prior to the call being answered will be held for a period of time to allow for the operator to answer the call. After the timer has expired, the caller will be able to hang-up and re-dial 9-1-1, or another number for assistance Calling Party Hold and Forced Disconnect Available in Alberta Only The PSAP attendant has full control of the call. The end-to-end connection is maintained until a valid ON-HOOK signal is sent from the PSAP attendant to the network. This prevents the call originator from terminating the call. This network resident feature is inherent to the network. The trunk is released only when an ON-HOOK signal is received from the PSAP attendant Abandoned Call Print The Abandoned Call Print feature sends available caller information as well as bell characters to the Real Time and Log printer in the event that a caller hangs up before the PSAP operator can answer the call. The PSAP may also elect to send the Abandoned Call ALI information to up to six additional targets, which may be other printers, video display terminals or CAD systems. The intent of this feature is to alert the operator of all abandoned calls and provide caller specific information Calling Party Switch Hook Status Available in Alberta Only This network feature automatically provides the PSAP attendant with an audible signal (Switch Hook Status) to indicate when the calling party has gone ON-HOOK. This tone is within the voice band and passed over the established voice path Ring-back to Caller Available in Alberta Only This network feature allows the PSAP attendant to generate ringing to the caller s set that is ON-HOOK or apply Receiver OFF-HOOK (ROH) tone to an OFF-HOOK set. A HOOK- June

10 FLASH signal and access code activates the feature Fixed Call Conference and Transfer This network feature gives the PSAP attendant the ability to add on (conference) a secondary agency by activating a transfer code associated with that specific agency Selective Call Conference and Transfer This network feature provides the PSAP attendant with the ability to add on a secondary agency (three way conference) by activating a transfer code associated with the type of agency required. The ESZ from the network resident database is used to make the appropriate connection to, for example, the predetermined fire dispatch centre serving the caller. June

11 2.0 OVERVIEW OF CALL IN PROGRESS When a subscriber dials 9-1-1, the call together with the caller s ANI, is routed from the call initiating Central Office on a dedicated trunk to a Selective Router switch. The Selective Router switch will match the caller s ANI to an ESZ and route the call to the PSAP serving the particular geographic location of the caller. The Selective Router switch is capable of supporting a number of terminal equipment configurations. Agencies can chose to operate with single-line terminal systems, standard key or PBX equipment. Two voice access technologies (see Section 3.1) are available to support these various modes of operation. Generally, when a call is routed to a PSAP the Selective Router switch produces a record containing ANI information plus identification of the agency. This data is forwarded to the ALI System for processing. When the PSAP answers the call the switch produces a record containing the line on which the call was answered. The caller s ALI is then displayed to the PSAP attendant associated with the specific line. If the call is delivered to a Key or PBX system, then additional information may be required from the terminal equipment to support the ALI feature. This additional information includes the line number of the facility connecting the PBX or Key system to the Selective Router and the position number of the telephone set used by the call taker to answer the call. This information is then combined with the data record from the Selective Router to enable the ALI System to display the caller s information on the correct call taker s data terminal. It is also appropriate for agencies using Key or PBX equipment to configure their equipment in such a manner as to have a one to one relationship between the facility connecting the PBX or Key system to the Selective Router and the position number of the telephone set used by the call taker to answer the call, thereby eliminating the need for the additional information to be sent from the terminal equipment. The role of the PSAP is to determine the nature of the caller s emergency, and transfer the call to the appropriate agency usually a fire, police or ambulance service. The call process described above is repeated as the call is transferred at the Selective Router switch to an access line connecting to the secondary agency. June

12 3.0 VOICE INTERFACE CHARACTERISTICS The terminal at the PSAP is connected directly to the DMS switch. The standard analogue primary exchange service access arrangements are described below. The interfaces must comply with the requirements defined in the References (Section 11.0). 3.1 Analog Voice Interface Requirements There are two types of Analogue Voice interfaces between the network and the PSAP terminal Two-Wire Loop or Ground Start Interface In order to activate the network-based features the terminal must be able to produce a standard HOOK FLASH (momentary ON-HOOK condition of 550 ± 50 ms) and standard DTMF dialling tones Electronic Business Set (EBS) Interface When specific keys are activated, the terminal equipment generates predefined codes described in Reference The DMS-100 interprets these codes and performs the appropriate function. June

13 4.0 FEATURE ACTIVATION This section describes the features provided to the PSAP for processing calls. 4.1 Two Wire Loop or Ground Start Interface Selective Call Conference and Transfer (Three Way Conference) When the PSAP attendant needs to connect a third party to the call in progress, the terminal shall produce HOOK-FLASH (550 ± 50 ms ON-HOOK). The Selective Router switch will respond by returning dial tone (350 Hz HZ at -13 dbm0/frequency at the switch) to the terminal. The terminal then generates a three digit DTMF code (*NN). The call is then automatically bridged as a three port call. (The NN code is defined locally.) Notes: If the PSAP attendant who has originated the three way call sends another HOOK- FLASH, the secondary agency, which was added on, will be disconnected by the network. If the secondary agency disconnects before the PSAP attendant (the original recipient of the call), the network will leave the call with the PSAP attendant. If the conference originator s terminal is placed ON-HOOK, the call will be automatically transferred to the secondary agency by the network. If the caller goes ON-HOOK after originating the emergency call, the PSAP attendant s terminal will receive the high tone from the DMS-100 switch. The PSAP attendant shall be able to originate a Ring-back to the caller. 4.2 Two Wire Loop or Ground Start Interface Ring-back to Caller (Available in the Province of Alberta Only) The PSAP attendant during a two party call can activate the Ring-back feature. When the terminal originating the call is placed ON-HOOK, the PSAP attendant shall be able to ring back the call originating set. If the originating terminal is OFF-HOOK the agent shall be able to deliver an audible tone (ROH) to the originator s receiver. When the Ring-back feature is to be activated by the call receiving PSAP terminal: a) The terminal produces a HOOK-FLASH. The Selective Router switch returns dial tone to the terminal. b) The terminal generates a three digit DTMF Ring-back code (*NN). c) The Selective Router switch then requests the emergency call originating Central Office switch to provide the ringing signal which is delivered to the ON-HOOK call originating terminal. When the feature is activated the PSAP attendant will hear an audible ring. June

14 4.3 EBS Interface Selective Call Conference and Transfer (Three Way Conference) For lines equipped with EBS, the terminal equipment shall be capable of producing messages to the Selective Router switch that corresponds to the conference call command as defined in Reference The Selective Router switch will be programmed to interpret the message and will perform the three-way conference. Notes: If the PSAP attendant who has originated the three way produces another conference call command, the secondary agency, which was added on, will be disconnected by the network. If the secondary agency disconnects before the PSAP attendant (the original recipient of the call), the network will leave the call with the PSAP attendant. If the conference originator s terminal is placed ON-HOOK, the call will be automatically transferred to the secondary agency by the network. If the caller goes ON-HOOK after originating the emergency call, the PSAP attendant s terminal will receive the high tone from the DMS-100 switch. The PSAP attendant shall be able to originate a Ring-back to the caller. 4.4 EBS Interface Ring-back to E Caller (Available in the Province of Alberta Only) The PSAP attendant during a two party call can activate the Ring-back feature. When the terminal originating the call is placed ON-HOOK, the PSAP attendant shall be able to ring back the call originating set. If the originating terminal is OFF-HOOK the agent shall be able to deliver an audible tone (ROH) to the originator s receiver. When the Ring-back feature is to be activated by the call receiving PSAP terminal: a) The equipment shall be capable of producing messages to the Selective Router switch, which corresponds to the key programmed with the Ring Back feature. b) The Selective Router switch then requests the emergency call originating Central Office switch to provide the ringing signal which is delivered to the ON-HOOK call originating terminal. When the feature is activated the PSAP attendant will hear an audible ring. June

15 5.0 ALI DATA INTERFACES A number of peripherals can be interfaced with the ALI system. These devices could facilitate, for example, a visual display of information associated with the call. Devices such as VT510 compatible display screens, desktop computers, printers, and Computer Aided Dispatch (CAD) systems could be used to enhance the response capability of the emergency agencies. The terminal devices connect to the ALI System via either terminal servers or modems. In either case the interface between the terminal devices and the terminal server or modem is a standard RS-232 connection. 5.1 Data Interface types VT510 Compatible Display Screen Interface The interface requirements for this type of display are contained in Section 6.0 of this document Service Printer Interface The interface requirements are described in Section 7.0 of this document. Usually two printers are used by the PSAP to produce a hard copy of the received call detail. The PSAP may also opt to replace their printers with data collection and analysis software running on a desktop computer Computer Aided Dispatch (CAD) Interface A Computer Aided Dispatch (CAD) system can be used in a call answer centre to facilitate the dispatch of a call. The details of interface requirements are described in Section 8.0 of this document ALI-PBX Communications A PBX can be used at a call answer centre to receive and transport the incoming voice call to an available answering attendant. A modem configuration is required on the PBX to transmit data back to the ALI System to support ALI display to the call attendant. The details are contained in Section 9.0 of this document Key System Interface A Key System Interface (KSI) can be used by a call answer centre to receive and transport the incoming voice call to an available answering attendant. The KSI can be interfaced with the ALI System to allow the call taker to receive the caller's information on the data terminal associated with the telephone set answering the call. The details of the KSI to the ALI System are contained in Section 10.0 of this document. June

16 6.0 ALI DISPLAY SCREEN LINK PROTOCOL 6.1 Physical Description The display screens are VT510 compatible terminals. VT510 compatible terminals can display 25 lines of 80 characters each, and support a speed of 9600 baud. The ALI system sends standard VT510 control sequences to generate displays. Screens and printers must support an EIA RS232C interface. They must provide / respond to signals on the followings pins as applicable: Table 1 - EIA RS232C pinout PIN Signal Name 1 Protective Ground 2 Transmit Data 3 Receive Data 4 Request To Send 5 Clear To Send 6 Data Set Ready 7 Signal Ground 8 Data Carrier Detect 20 Data Terminal Ready 6.2 Service Printers or Display Screen Receiving a Message When a call is received, the caller s address is displayed automatically on the answering agent s screen. Each site is normally equipped with a printer that prints the caller s information for all dialled calls coming into the emergency centre (Real Time Printer). Some PSAPs also have a Log Printer that prints the call history of each call after the call taker releases the call. 6.3 Data Link Management Only one link is used for ALI-Service printer and/or display screen communications and the entire data flow uses that link at the transmission speed of 9600 baud. 6.4 Communication Protocol An ALI message to a service printer and / or a display screen is composed of a sequence of ASCII characters. A series of standard VT510 control sequences are used to control positioning on the display June

17 screens. Data in the form of keystrokes is also read from the terminal VT510 terminal in order to implement limited screen control. This includes refreshing of the screen data, scrolling through a history of previous call information and activating different panels for multi-panel video terminal displays. The ALI system supports up to three panels in a multi-panel display. 6.5 Single panel video screen layout VTI700 Call Date: 2004/01/25 Call Time: 13:58:47 Phone #: (604) Class: RES Name: TELUS *** TEST CAD PACKET *** Address: A ANYWHERE NW T2G 4Y5 Comm/Muni: VANCOUVER ESZ: Comment: Test comment field Fire: TEST FIRE DEPARTMENT (604) Police: TEST POLICE DEPARTMENT (604) EMS: TEST EMS DEPARTMENT (604) LSP Name: TELUS COMMUNICATIONS (800) The Field Size column in the following table indicates the maximum number of characters assigned to the respective field.
