IMl66-107 Description Cf System Features
Intercom Features - continued
Tone Or Voice Signalling
The system allows intercom calls to be tone signalled
or voice signalled as the users desire; however, the
programmer uses system class of service
programming procedures to determine which
signalling method the system will employed as the
primary method. Regardless of the programmer’s
arrangement, telephone users can take action to use
the alternate method when they need it. See the
previous paragraph titled intercom Call Progress
Tones for a discussion of the intercom signalling tones.
Voice Announce Blocking
This feature allows station users to block voice
announced intercom signalling by dialing a code or
pressing a programmable button programmed for that
purpose. The programmable button used to block
voice signalling is enabled by station class of service
programming.
Key System/Hybrid Configuration
The system can operate as either a key system (KF
designation) or as a hybrid (MF designation) system.
In the past, this digital telephone system provided a
hardware strap that installers could move to
distinguish between hybrid system and key system
operation; however, recent rulings by the FCC have
eliminated the need for the hardware strap. Therefore,
with software release revision 11 A, whenever the
programmer assigns lines to line groups the system
automatically assumes the hybrid mode.
The KF and MF designations are equipment type
categories as stipulated in FCC rules and regulations,
Part 68, and appear as part of the FCC Registration
Number on the equipment label. The installer must
report the appropriate registration number to the
telephone company at the time of connection along
with other FCC mandated information. Operationally,
the hybrid configuration allows dial access to
(automatic selection of) outgoing lines. The specific
system feature that is enabled by the multifunction
(hybrid) configuration is Line Group (Including Dial
Access). Since this is a PBX type feature, it may incur
a higher monthly tariff to the telephone company.

LCD Support .
The system supports the use of digital telephones
having a Liquid Crystal Display (LCD). The display is
capable of providing the station user with a visual
presentation of: call cost, call duration, number dialed,
name of called station, name of active feature, date
and time, and programming prompts.
Interactive Button Support
Beginning with software release 11 A, the digital
telephone system supports the DigiTech LCD
speakerphone with a revision letter of I and later.
This LCD speakerphone provides the user with three
interactive buttons and expanded LCD displays as a
standard feature. The interactive buttons provide the
user with quick easy access to system features and
straight-forward button programming without dialing
codes. The expanded displays prompt the telephone
user on the operation and progress of many of the
telephone features and provides designations for the
interactive buttons. Since the interactive buttons
provide many user features, their immediate functions
vary with the feature. The button functions change to
match the feature that the user is currently operating.
At any given time, the current button designations
show in the display window.
Beginning with software release 118, the digital
telephone system provides Americom LCD
speakerphones (product codes 701 OS and 7016s)
with the same interactive button support. This support
is disabled at default but can be enabled by the
system programmer whenever it is required.
Beginning with software release 128, the system
includes /mpact telephone support. The impact LCD
speakerphones (product code 8024s and 8012s) also
provide interactive button and expanded display
operation to the telephone users as a standard feature.
