CODE RESTRICTION
Code Restriction for outgoing calls is based on the first eight digits dialed.
Code Restriction denies outside calls based on number dialed over a trunk
group and accommodates equal access to Other Common Carriers (OCCs)
and CO Feature Codes. This eliminates unauthorized calls and configures
system calling functions to provide cost control.
C-22
CO/PBX TIE LINE DIGIT RESTRICTION
CO/PBX, Tie Line Digit Restriction eliminates unauthorized calls by
restricting the number of digits that can be dialed from a station on an
outside line.
C-23
CO MESSAGE WAITING INDICATION
This feature provides a Message Waiting Indication when Voice Mail from
the Central Office is used. The CO uses Visual Message Waiting Indication
(VMWI) standards to provide this feature. When VMWI is used, the Electra
Elite IPK provides a flashing LED on a line key assigned with the trunk
appearance.
R2000 or higher is required.
C-24
COMPUTER TELEPHONY INTEGRATION
CTI integrates computers and telephones to allow access of sophisticated
communication services using telephone lines. The Telephony Application
Programming Interface (TAPI) supports speech and data transmissions,
allows a variety of attachment devices, and supports complex functions such
as conference calls, call waiting, and voice mail. Through TAPI, all elements
of telephone usage, including simple dial and voice calls, can be controlled
by Windows 95 and higher Windows versions.
CTI is implemented using a Computer Telephony Adapter (CT(A)-R/CTA-U
Unit) or CT(U)-R/CTU(S)-U Unit. The CT(A)-R Unit can be attached to any
DTH/ITH/DTR terminal except the DTR-2DT-1 TEL, or the CTA-U Unit can
be attached to any DTU/DTP terminal except the DTP-2DT-1 TEL to provide
a serial RS-232 connector to the PC that allows TAPI applications to control
telephony features of the KSU.
The CT(U)-R Unit can be attached to any DTH/ITH/DTR terminal except the
DTR-2DT-1 TEL or the CTU(S)-U Unit can be attached to any DTU/DTP
terminal except the DTP-2DT-1 TEL to provide a Universal Serial Bus (USB)
connection to the PC that allows TAPI applications to control telephony
features on the KSU.
When 5-, 6-, or 7-digit station numbers are used, this feature is unavailable.
