E911 Compatibility
E911 Compatibility ensures that emergency calls always get through. If an
emergency occurs, a user 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

Emergency Routing

Calling Party Identification
Facsimile CO Branch Connection
The UNIVERGE SV9100 system provides branch connection of locally provided
facsimile machines to CO/PBX lines. Additional dedicated CO/PBX lines are not
required for a facsimile to operate. The facsimile shares any CO/PBX line on the COI
Package and Power Failure (PF) circuit.
Flash
Flash allows an extension user to access certain CO and PBX features by
interrupting the trunk loop current. Flash lets an extension user take full advantage of
whatever features the connected Telco or PBX offers. You must set the Flash
parameters for compatibility with the connected Telco or PBX.
IMPORTANT - PLEASE NOTE THE FOLLOWING!
1. 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.
2. Do not use an asterisk 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.
3. 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.
