E911 Compatibility 2 - 411
E
E911 Compatibility
Description
E911 Compatibility ensures that emergency calls always get through. If an emergency
occurs, a user simply goes to any telephone, lifts the handset and dials 911. The system
built-in E911 compatibility places the emergency call even if the user forgets to dial an access
code or press a line key. The E911 abilities include:

Attendant Notification
The attendant receives a notification each time a co-worker dials an emergency 911
call. This notification is the co-worker’s name and number display optionally
accompanied by an audible alarm. Notification occurs regardless of whether the
attendant is idle or busy on a call. You can optionally extend this ability to other
supervisory extensions as well.
IMPORTANT - PLEASE NOTE THE FOLLOWING!
1. All local trunks or the trunk connected to external 911 equipment must be put in the
E911 route.
Placing all the local trunks into the E911 route assures that any user may make a
call to 911.
2. When ARS is NOT enabled and the system allows trunk access by dialing 9 , single line
telephones disregard Program 20-03-03 – System Options for Single Lines Telephones - SLT
DTMF Dial to Trunk Lines. This prevents the system from connecting to a trunk until all the
digits are dialed. This can be avoided by using either 8 or 9x (but not 91) as the trunk access
code. Be aware that this change requires additional programming changes.
3. When using external E911 equipment , do not allow analog single line telephones to directly
access trunks. When an analog SLT directly accesses a trunk ( # 9 xxx) and dials 911, the
system does not follow the 911 routing. If your system is connected to external E911
equipment, the system does not route the call to that equipment.
4. Do not use

within a PBX access code if the Account Code feature is used. With the
Account Code feature enabled, if

is used in the access code, the trunk stops sending digits
to the central office after the

is sent.
5. Finally, but most importantly, TEST - TEST - TEST! Due to the nature of the E911 feature,
it is imperative that when programming this, or any other feature, to be aware of the
consequences. Make sure to test the extensions with the E911 feature to confirm that other
features do not prevent the call from being completed. When using external equipment, make
sure the dial treatment tables are working properly.
