Enhanced 911 (E911) Configuration - Nortel Enterprise Edge 2.0 Programming Manual

Enhanced 911 (E911) Configuration

Government rules vary for support of Enhanced 911 (E911) dialing service by
Customer Premises Equipment. Legislation may require that the Customer
Premises Equipment give a more precise location of the source of a 911 call than
the billing address of the central office line. Consult your service provider about the
laws and regulations.
Use the following configuration rules when installing the Enterprise Edge system,
to assure compliance with local regulations:
• When equipped with PRI trunks, Enterprise Edge can deliver the Calling Line
ID of a telephone dialing 911 through the Public Switched Telephone Network,
if the proper programming has been implemented and PRI trunk service has
been installed by the service provider. If you are using ISDN PRI, implement
OLI programming and Business Name programming to add the Set ID to the
CLASS information.
• By default, Restriction Filter 02 is assigned to all sets on startup. There are no
restrictions applied in Restriction Filters 02-99. Restriction Filter 01 has
restrictions, but 911 is an Exception for this filter. For information on how to
change the Restrictions, refer to
• When using other trunk interfaces, you can assign separate line pools to groups
of telephones in different areas (for example, in different buildings, floors or
sections).
• Be careful when using the Set Relocation feature. You may have to reprogram
the line pool access to send the right location on 911 calls.
• Configure the 911 destination code to dial out over a Normal Schedule in all
applicable Service Modes, as this is the default route should any other
programmed routing attempts fail. When using PRI interfaces, make sure all
sets can use the PRI line pool that the Normal Schedule route uses.
