Uninstalled Trunks in Trunk Group Prevent Call from Dialing Out
By system default, all trunks in Program 14-05-01 : Trunk Group are in group 1. When placing a
911 call, the system will try to access the trunks deÞned in the group. If the trunks do not exist, the
call will not dial out. In order for E911 to function correctly, remove any uninstalled trunks from
the trunk group.
The system software will be changed in a future release to ignore trunks which have no voltage
present on the PCB.
Using Dial Number Preview with 9+911 Call Will Not Dial Out When All Trunks Busy
If Program 21-01-12 : System Options for Outgoing Calls, Dial 911 Routing Without Trunk
Access is set to "0" (trunk access code required), when using the Dial Number Preview feature and
dialing 9+911, if all trunks are busy, the user will hear a busy signal and the call will not dial out.
If option 21-01-12 is set to "1" (trunk access code not required) and using Dial Number Preview,
911 is dialed, the system will disconnect a trunk and dial the call.
Dial Number Preview is when a telephone number is Þrst dialed (previewing the number in the dis-
play) then pressing the CALL or line key to place the call.
Networked IP Phones Can Follow ARS Class of Service Matching to Call Local
Authorities
When using IP telephones at a remote site (Site B) which are registered to the main system (Site A),
you can use the ARS Class of Service Matching feature to route 911 calls to the local authorities at
a remote location. Without this programming, since the phones are registered to the main site, when
911 calls are placed by IP phones, the local authorities at the main site (Site A) would be called.
Product Description
E911 Compatibility uses the ßexibility of the Automatic Route Selection Call Route Options
to route 911 emergency calls (even in systems in which ARS is not enabled).
● E911 Outgoing Dialing
The E911 calls follow the trunk group route programming. It is possible to use the ßexibil-
ity of the Automatic Route Selection Call Route Options for additional routing options.

Forced Disconnect Follows Timer to Disconnect Call
When all lines in the programmed route are busy and the system must drop a call in order
to place a 911 call, the system will wait the amount of time set in Program 81-01 before
disconnecting the call.
Compatibility with Customer Provided E911 Equipment
The system can automatically send a 911 call to customer-provided E911 equipment (such as
the Proctor 911 ANI-LINK System II). The E911 equipment will dial emergency service and
provide the caller's extension number to the emergency personnel. When using this type of
equipment, the system must be programmed to send E911 calls to the trunk connected to the
E911 box. This is done by assigning the trunk to the E911 trunk group and using ARS to route
all 911 calls to that port. The Dial Treatment must then be set to send the extension number
and '911' to that port. This is usually accomplished using XRE in the Dial Treatment, but
check the requirements of your E911 box.
Calling Party IdentiÞcation
With ISDN installed, the system can provide the calling party's telephone number and exten-
sion number. No additional customer-provided 911 equipment is required.
