Enhanced 911 (E911) configuration
Government rules vary about support for 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 Business Communications Manager
system to assure compliance with local regulations:
• When equipped with PRI trunks, Business Communications Manager 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.
Task:
Set up emergency access number to comply with local regulations.
