Modular ICS 6.0 System Coordinator Guide
Public calls connect your set with a Central
Office (CO). DID and DOD calls are supported.
Private calls connect your set with a private
network. DID and DOD calls are supported. A
private dialing plan may be used.
Tie lines are private incoming and outgoing
lines that connect Private Branch Exchanges
(PBX) such as Norstar.
Foreign Exchange calls connect your Norstar
set to a remote CO. It provides the equivalent of
local service at the distant exchange.
Outwats is for outgoing calls. This allows you
to originate calls to telephones in a specific
geographical area called a zone or band.
Typically a flat monthly fee is charged for this
service.
Inwats is a type of long distance service which
allows you to receive calls originating within
specified areas without a charge to the caller. A
toll-free number is assigned to allow for
reversed billing.
