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 with an external paging
amplifier. The paging amplifier can then be dial-accessed by stations in the system.
DTMF tones can be dialed through the line port to provide zone selection if provided by
the external paging amplifier. The dedicated paging port does not support any
“talk-back” capability even if such a feature is provided by the external equipment. The
line class of service programming arranges a line port for external paging interface. The
system precedes an announcement through the paging port with an alerting tone.
Programmers can choose between an intercom tone or a DTMF signaling tone for this
paging alert tone. They should choose the intercom tone for a soft alert and choose the
DTMF tone for a loud alert.

Feature Inhibit
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.
Flexible Ringing Assignments
Ringing assignments are programmable on a per station/per line basis. Ringing 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.
