E911 Caller ID Support for System Stations

With enhanced 911 (E911) service, the service provider’s equipment automatically routes 911 calls

to the emergency services operator along with identifying information that provides a geographic

location of the caller’s telephone. In the case of PBX or hybrid telephone systems, E911 calls that

originate from a telephone connected to the system cause the service provider’s equipment to send

along the geographic location of the PBX but not the actual location of the caller’s telephone.

Beginning with software Release 170, the CCB software supports outbound automatic number

identification (ANI) of individual system telephones for E911 purposes. This software enhancement

allows a user-provided proxy device that installers connect to the system to transmit the location of

system stations that originate an E911 call.

Programming for E911 Caller ID Support

Program the following VMMI items to fully enable the E911 Caller ID Support.

E911 Line Marking—Under LINE/LINE PROGRAMMING/LINE TYPE SPECIFIC, when

configuring an analog domestic E&M Tie or Ground Start Line, select the E911 Outbound ANI to

mark or clear the line as one that is connected to a proxy device for caller identification.

Emergency Number Alarm Level—Under SMDA/SMDR/EMERGENCY NUMBERS, select

the emergency number (911) and specify the Alarm Level to be generated and stored when that

number is dialed.

Emergency Call Feature Code—Under SYSTEM/FEATURE NUMBERS, select the Make

Emergency Call feature code, and enter a dialable string that will originate the emergency call.

E-911 Feature Code Parameters—Under SYSTEM/PARAMETERS/OPTION 2, enter a

translation that translates the feature code into a dialable string. Installers select the line group for the

feature code to use; otherwise, the system chooses line group one as a default.

E911 Line Type

With the addition of the FXDIDEM-MF line board for the FX II, an E911 line type is provided. The

E911 line type is a direct ringing, inbound line that supports E-911 protocols. This feature adds the

following type specific selections to the programming choices: Wink Between Sequences, Reverse

Before Ringing, and Collect Info After ANI. Further, in support of the E-911 Line feature, there are

two system timing selections for: Intersequence Wink and Re-ring Wink/Flash.

To make the necessary VMMI programming for E911 Line Type, add the board to the system under

the Board/Slot Assignment screen; choose an E911 line type under Lines/Line

Programming/Line Attributes screen; click the check box for the assigned parameters under

Lines/Line Programming/Line Type Specific screen; and choose desired timing under System

Timing/E911 Timing screen.
