Emergency 911 Dialing

Modular ICS 4.0 with the ISDN PRI feature is capable of
transmitting the telephone number and internal extension
number of a calling station dialing 911 to the Public Switched
Telephone Network. State and local requirements for support
of Emergency 911 Dialing service by Customer Premises
Equipment vary. Consult your local telecommunications
service provider regarding compliance with applicable laws
and regulations.
If transmission of internal extension numbers is not required or
desired, then it is recommended that the System Coordinator
maintain a site map or location directory that allows
emergency personnel to rapidly locate a Norstar set given its
DID number. This list should be kept up to date and readily
available, and can be included in the Programming Record.

2-way DID

With PRI the same lines can be used for receiving direct
inward dialing (DID) and for making direct outward dialing
(DOD) calls.
