control telephone:  A control 
telephone can place the  lines  for  which 
it has responsibility in or out of a 
Service Mode. The direct-dial telephone 
is a control telephone for directing calls 
to the extra direct-dial telephone. A 
telephone is made a control telephone 
and has lines assigned to it under 
Common settings in Services 
programming. 
COS:  See Class of Service.
cursor:  A short horizontal line that 
appears on the Norstar telephone 
display to indicate that characters can be 
entered using the dialpad.
Custom Call Routing:   Answering 
and transferring calls can be taken over 
by CCR. The system answers the call 
and plays a recorded greeting. Callers 
are given options to route their call by 
pressing a digit.
D
D channel (Data channel): An 
ISDN standard transmission channel 
that is packet-switched and is used for 
call setup, signalling and data 
transmission.
Data channel: See D channel.
Data terminal:  A device such as a 
modem that can be used to transfer data 
instead of sound over a telephone 
network. You cannot use Norstar 
programming to set up such devices. 
See the documentation that 
accompanies the device.
Date:  See Show Time or Time and 
Date.
defaults:  The settings for all Norstar 
features when the system is first 
installed. Settings are changed from 
their defaults in programming. In this 
manual, default settings are shown in 
bold text.Delayed Ring Transfer (DRT) to

special features of the Automatic and 
Pre-Dial modes are available only  when 
you dial on-hook.
Direct-dial:  A feature that allows you 
to dial a designated telephone in your 
Norstar system with a single digit. Each 
telephone in the system can be assigned 
to the direct-dial telephone. The direct-
dial telephone is established under 
Direct-dial in System programming. 
Telephones are assigned to the direct-
dial telephone under Capabilities in 
Terminals and Sets programming. 
Direct-dial #:  A digit used system- 
wide to call the Direct-dial telephone. 
The digit is assigned under Access 
codes in System programming.

DISA DN:  The received number 
assigned to the Norstar direct inward 
system access facility. If a caller dials a 
number that is assigned to the DISA

according to a Services schedule 
(sometimes called least cost routing).
