PULL OUT DIRECTORY
Each desk mounted telephone is equipped with a pull
out directory. This directory can be used for recording
the system speed dial, station speed dial, or other
frequently called numbers.
PULSE/TONE SWITCHABLE
When rotary dial lines are installed, the user can
switch from pulse (rotary dial signals) to tone (Dual
Tone Multiple Frequency signals - DTMF). This
feature is useful for accessing special circuits requiring
DTMF tones such as banking machines, etc. The
system is programmed on a per line basis to allow this
feature at all stations. The system or administration
class of service programming enables this feature on a
per line basis.
RINGING LINE PREFERENCE
The system can be programmed on a per station basis
to provide ringing line preference on all lines
programmed for ringing at a station.
When ringing line preference is enabled at a station,
taking the station off-hook automatically connects it to
any outside line which happens to be ringing at the
station. A line button will not have to be pressed. The
ability of a particular station to answer a ringing line
without line selection is enabled by the system or
administration class of service programming.
SECURE OFF-HOOK VOICE ANNOUNCE
With the secure off-hook voice announce (SOHVA)
feature, an announcement can be made from one
station to another station that is off-hook and busy on
a call. The SOHVA announcement is made in a
manner that prevents the distant on-line party from
hearing it or from hearing the verbal response to it
because the MUTE button must be pressed for reply.
The SOHVA feature is available at stations that are
equipped with a telephone that includes SOHVA
capability. The telephone requires two data-paired
station ports to provide SOHVA operation.
A SOHVA call is preceded by a ring burst. Then,
several quick tone bursts followed by the
announcement are delivered through the handset
receiver of the telephone. Delivering the
announcement in this manner prevents the distant
party from hearing it. A station employing a
speakerphone being operated in a handsfree mode
will receive a ring burst and can then be taken off-hook
to receive the SOHVA call. The announcing caller
receives several tone bursts to alert them that they are
making a SOHVA call and that they may not get a
reply should the called party choose to not respond.
Response to the SOHVA call is effected by pressing
and holding the MUTE button and speaking into the
handset. Because the MUTE button is pressed, the
distant party is prevented from hearing the response.
The system provides SOHVA operation at every
station port; however, a station that has the voice
announce blocking feature turned on cannot receive a
SOHVA call. Also, on handset equipped telephones,
the telephone headset cannot be used to receive a
SOHVA call.
Station clas of service programming is used to
program a station port to be a multiline telephone port
and the data-paired port as a console with call
announce port. Also refer to the discussion titled:
Off-Hook Voice Announce with Handsfree Answerback
and to the Chapter 3 paragraph titled: Secure
Off-Hook Voice Announce Station found on page 3-11.
SECURE OFF-HOOK VOICE ANNOUNCE (SOHVA)
GROUPS
The ability to receive and originate SOHVA and OHVA
calls is provided to every station in the system. Any
station in the system can send a SOHVA or OHVA call
to any other SOHVA or OHVA-equipped station in the
system. Through this feature, the ability of a station to
receive and/or originate SOHVA or OHVA calls can be
disabled through programming so that certain stations
can be grouped together for SOHVA or OHVA calling
between one another while other stations in the
system are excluded from this group. Stations can be
arranged in up to four different groups for exclusive
SOHVA or OHVA calling. For example, the stations of
an executive and an assistant can be arranged into the
same group as follows: Program the executive’s
station for receive in group 1 and program the
assistant’s station for originate in group 1. Do not
program any other stations to have receive or originate
capability in group 1. This arrangement provides
exclusive SOHVA or OHVA calling between the two
stations. More executive stations can be programmed
to have receive capability in group 1 thus giving the
assistant the ability to make SOHVA or OHVA calls to
them as well. These executive stations in group 1
cannot make SOHVA or OHVA calls to one another,
however, since they do not have originate capability.
Both class of service and administration programming
can be used to form SOHVA groups. Also refer to the
discussion titled, Secure Off-Hook Voice Announce
and Off-Hook Voice Announce with Handsfree
Answerback.
SELF DIAGNOSTICS
Each station can execute a self test when so enabled.
This test verifies processor, indicator, and tone
functions. Instructions for activating self diagnostics
are provided in Chapter 3, Section 3 of this publication.
