User guide

automatically connect the station to any assigned line
that is idle and has been arranged for this feature.
The line button will not have to be pressed. This
feature is mutually exclusive with prime line automatic.
Programming for this feature is through either system
or administration programming.
I HOLD AND I USE INDICATIONS
The light associated with a line button provides a
visual indication of the status of that line. When a
station user has a line in-use or on-hold at a station,
the light indication provided at that station is of a
different flash rate than the indication provided at the
other stations in the system.
INTERCOM CALL PROGRESS TONES
Intercom call progress is marked by special tones. A
steady tone is provided for dial tone. For tone
signalled intercom calls, a two-tone burst is sounded
every four seconds at a called station and returned to
the caller as ring-back. For a voice signalled intercom
call, a single tone burst is sounded at a called station
and returned to the caller as ring-back. When a called
station is busy on an outside call, the feed-back
supplied to the caller is programmable with class of
service programming. This feed-back can be either a
ring-back tone or a busy tone. When set for ring-back
tone, the called station sounds subdued ringing during
the call. When a called station is busy on the
intercom, a busy signal of one tone burst sounded
each second returns to the calling station.
INTERCOM LINE LOCKOUT
Refer to the discussion titled, Voice Announce
Blocking.
INTERCOM LINE TIMEOUT
Should the intercom line be selected with no dialing or
other action taking place, the intercom will timeout
after ten seconds, and return to an idle state.
LAST NUMBER REDIAL
Each station is provided with a last number redial
feature. This feature will save thirty digits of the last
outside number dialed. A newly dialed number will
always automatically replace a previously dialed
number. Upon command, the system will choose a
line and redial the saved number. The system will first
choose the prime line if assigned and idle. If it is busy
or unavailable, the system will choose any line
assigned to idle line preference. If they are
unavailable, the system will chose the last line used at
the station. If it is busy, no further choice is made.
Also refer to the discussion titled, Automatic Pause
Insertion.
LCD SUPPORT
The common equipment can be field modified with an
optional up-grade kit which allow the system to
support the use of LCD speakerphones having a
Liquid Crystal Display (LCD). The LCD speakerphone
ports are identified by system or administration
programming.
When a system is modified, the model code of it is
changed from an N prefix to a K prefix (i.e. N1024
becomes K1024, etc.).
LINE PRESELECTION
A line can be manually selected before lifting the
handset (for handsfree dialing) or after the handset is
lifted.
LINE TYPE
A line port is programmed as to type. The program
type is chosen based upon the toll restriction that is to
be applied to calls made over the line connected to
that port. A line port is assigned as type 1 when any
enabled toll restriction is to be applied with the first
digit dialed. Such a line type is often assigned when a
CO line is connected. A line port is assigned as type 2
when any enabled toll restriction is to be applied
beginning with the second digit dialed. Such a line
type is often assigned when a PBX or CENTREX line
with any trunk access code is connected. A line port is
assigned as type 3 when any enabled toll restriction is
to be applied beginning with the second digit dialed
whenever the first digit is a 9. If the first digit is not a
9, no restriction is applied. Such a line type is often
assigned when a PBX or CENTREX line with a trunk
access code of 9 is connected. Line types can only be
selected as part of system class of service
programming.
MANUAL HOLD
A button activated feature at each station will place an
outside line on hold. Pressing the HOLD button holds
the call, provides a distinctive flash rate of the line
button indicator, and allows the user to access other
station features. The holding station or any other
station which has access to the line can retrieve the
held call.
MEMORY RETENTION WITHOUT BATTERIES
Independent of the optional battery pack, the system
memory is electronically protected during AC power
failures by an electronic component sometimes
referred to as a “super-cap”. The stored program data
will remain in memory for a minimum of 30 hours
provided that the system has been powered
continuously for at least 30 minutes prior to the power
failure or disconnection.
