Modular ICS 7.0 System Coordinator Guide
Name and number blocking for PRI
When activated,
≤°⁄·
allows you to block the
outgoing name and/or number on a per-call basis. Name and
number blocking can be used with a Norstar or BST telephone,
but not with an ISDN terminal.
Consult your customer service representative to determine
whether or not this feature is compatible with your provider.
Emergency 911 Dialing
Modular ICS 7.0 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 or BST
telephone, given its DID number. This list should be kept up
to date and readily available, and can be included with the
Programming Record.
Two-way DID
With PRI, the same lines can be used for receiving direct
inward dialing (DID) and for making direct outward dialing
(DOD) calls.
The dialing plan determines how calls are routed.
