CTI (Computer Telephony Integration) Link
If you program a CTI link for a jack that is already programmed for 2B data, the
CTI programming overrides the 2B data programming, and a 2B data device that
you later connect to the jack will not function as such. For more information about
2B data, see
‘‘Digital Data Calls’’ on page 183
You cannot use a system programming port as the CTI link extension.
You cannot program a port as a CTI link if it has a telephone or other device
connected to it. However, the port may have the CTI link hardware plugged in.
You cannot program a CTI link port on an MLX module with firmware vintage 29.
Use an earlier or later vintage.
Because CTI link programming requires that you busy-out the control unit slot
where the MLX module with the CTI link is being added or removed, either you
must use SPM software to program the CTI link, or the link must be located on a
different module from the one where the system programming MLX-20L console
is connected. The busy-out programming procedure is available from the system’s
Maintenance menu. For details about busying-out a slot in the control unit, see the
System Manager’s Guide
.
An extension programmed as a CTI link should not be used as a phantom
extension—an extension that does not serve equipment plugged into the system
but used for a special purpose, for example, coverage by a voice messaging
system.
Telephone Differences

Queued Call Consoles
9
A call to a QCC does not initiate screen pop at the operator position, which cannot
use a CTI application. It can initiate screen pop at a screen pop capable-extension
either when an operator transfers a call immediately, or during consultation when
the operator talks to the system user before transferring a call. The screen pop
shows calling party identification information, if available.
Direct-Line Consoles

A DLC can function either as an operator and
unmonitored
extension or it can use
a CTI application and function as a
monitored extension
. An unmonitored
extension uses the telephone to transfer or conference a call.
