operations can be performed. Station class of service
programming allows certain buttons to be
programmed as dynamic line buttons

FEATURE INHIBIT

END-TO-END

ON INTERCOM

After an intercom call has been established, the system
can continue to send dialing signals (DTMF tones)
through the intercom path. This feature can be

performed from every station in the system, and is

used by peripherals such as voice mail equipment.

A large array of individual features can be disabled
system-wide to provide a basic telephone system. A
basic telephone system is useful for installation
environments where a large proportion of the stations
are accessible to unauthorized users thus subject to
tampering or for environments where station users
must be limited as to the variety of features allowed to

them. Features are disabled by system class of

service. Once disabled, they can enabled by turning
on all features at once using the system default
programming.

After an outside call has been established, the system
can continue to send dialing signals (DTMF tones)

through the

network and have them received at

the distant end for inward call completion (bank by

phone, etc.).

conventional, off-hook dialing

feature can be performed from every station in the
system.

EXCLUSIVE HOLD

Exclusive hold prohibits a held call from being
retrieved by any other station. The exclusive hold
condition also links the held call to the timed hold
recall timeout feature. After timeout, audible and visual
signalling will occur and the exclusive hold condition

will revert to a normal line hold condition.

EXCLUSIVE HOLD SYSTEM-WIDE

ENABLE/DISABLE

This feature allow systems that do not require

exclusive hold capability to have it turned off
system-wide through programming. System class of
service programming is used to enable or disable
exclusive hold.

EXECUTIVE/ATTENDANT OVERRIDE

This feature allows the user of a station, upon
encountering a busy signal at another station, to dial a
code that will override the busy signal of a call, sound
a warning tone, and allow access to the existing
conversation. This feature is enabled through station
class of service programming.

EXTERNAL PAGING INTERFACE

A dedicated paging port or a spare line port can be

interfaced

an external paging amplifier. The

paging amplifier can then be dial-accessed by stations

in the system.

tones can be dialed through the

line port to provide zone selection

provided by the

external paging amplifier. The dedicated paging
does not support any “talk-back’ capability even if such
a feature is provided by the external equipment. The

FLEXIBLE RINGING ASSIGNMENTS

Ringing assignments are programmable on a per

station/per line basis. Pinging can be controlled for
every line that has an appearance at each station.

Delayed ringing is assigned to certain lines at each

station through station class of service programming.

Refer to the paragraph titled: Delayed Ringing.

FLEXIBLE RINGING

ASSIGNMENTS OF PA PORT

The PA port can be programmed for flexible ringing

assignments and zone pages. Any desired lines can
be programmed for direct ring, delay ring, or night

transfer (of ringing) at this port. Paging can be to

programmed zone or to

A speaker can be

connected to the PA port to sound the ringing that is

generated by the system and sent to this port and
paging announcements when they are sent to the
programmed zone. Using such an arrangement, it is
possible for a user to determine that certain lines are
ringing, such as in a night transfer (of ringing) mode,
and go to the nearest telephone and answer the call.
The most common use for this arrangement is as a
night bell eliminating the need for external equipment
as required with the common ringer and auxiliary
ringer interface. The speaker cannot be used for voice
response as the path is one-way only. Use system
class of service programming to assign ringing and
paging to a PA port.

FLEXIBLE STATION AND LINE

CLASS OF SERVICE CONTROL

The extension number of a station and all other
programmable attributes that are initially assigned to a
particular station port and the line, along with all

programmable line attributes that are initially
connected to a particular line port can be re-assigned
to a different port through programming action. This
feature allows adds, moves, and changes without
