17.0 This section describes the various types of telephones that
the 
OMNI SI supports.
17.1 The system supports all standard DP (Dial Pulse)
telephones, DTMF (Dual Tone Multi-frequency) telephones,
Display Telephones, and Stand-Alone Feature Telephones. All
of these instruments interface to the system via standard tip and
ring connections to the FB-17254-A PLCC (PCM Line
Interface) card.
17.2 The system can interface with external equipment via
standard lines and long-loop lines. The long-loop lines can be
loaded or non-loaded. See TL-130300-1001 for line
interfacing. Cards are described in section 3.0 of this document.
17.3 The Display Telephone (Figure 
17.1), a compact, desk-top
console unit, contains a 12-pushbutton DTMF keypad, a 
four-character liquid-crystal diode display, a handset, and a
hookswitch assembly.
The Display Telephone interfaces with the system via a the 
FB-17254-A PLCC (PCM Line Interface 
)card located in a PCMUS
slot. This card provides the analog voice channel (line circuit).
The telephone displays in its LCD either the calling or the called
number. Customer needs determined the instrument’s
configuration. The configuration is defined in data base through
the non-displayable class of service. Either entry directs the
system to transmit DTMF signals over the tip and ring lines
before applying ringing voltage. The calling number display
provides the user with the station number of the calling party on
internal calls and offers a blank display on outside calls. The
called number display mode is most effectively used in a
secretarial or screening type of operation. Calls diverted to the
Display Telephone indicate the station that was called.
The Display Telephone can be powered by either a 24 VAC
transformer or -48 VDC transformer. Power and tip and ring
connections to the Display Telephone are described in 
TL-
130300-l 001.

Display TelephoneStand -Alone17.4 The Stand-Alone Featurephone, a compact
Featurephonemicroprocessor-controlled, desk-top console unit, contains a
12-pushbutton DTMF keypad, a 
16- or 24-character liquid
crystal diode display, a handset, a hookswitch assembly, and 8
or 16 feature pushbuttons. It can be connected to most PABX
systems.
The Stand-Alone Featurephone interfaces with the system via
the PLCC, located in a PCMUS. The PLCC card provides the
analog voice channel (line circuit).
Power to the Stand-Alone Featurephone is provided by either a
24 VAC transformer or -48 VDC transformer, which is supplied
by the system equipment cabinet.

IFP (Integrated17.5 The IFP, available in an analog version or a digital version,
Featurephone)is a multi-featured telephone instrument. The IFP only operates
when used with the 
OMNI PABX. The Featurephone is
approximately 4.5 inches high, 10 inches deep, and 10 inches
wide. It weighs approximately 3 pounds and comes in antique
white with a wood-grain 
facemat.
IFPs are available with either 8 or 16 feature pushbuttons and
associated LED indicators. An optional AOM 
(Add-On-Module), connecting directly to the IFP, provides an additional 30
feature pushbuttons and 
LEDs. Microprocessor control of the
instrument allows the user to select the functions for any
pushbutton/LED by simple programming steps. More than 47
features are available to choose from, which allows the
instrument to be programmed to meet specific user needs.
8187S-227 
						

							TL-130500-1001Figure 17.3Integrated Featurephone with DSSThe IFP contains a loudspeaker and an amplifier and volume
control. Whenever the monitor or optional speakerphone is
active, the volume control and loudspeaker allow the user to
listen to the line without lifting the handset off-hook. The
loudspeaker produces audible alerting ringing tones of different
cadences, with the volume and pitch being controlled by the IFP
user’s programming instructions. Audible beeps provide
confirmation signals during programming operations.
An LCD, contained in the IFP, presents informative messages
from the system to the user in addition to displaying 
user-activated functions. Uppercase alpha characters plus numerics
and symbols are used, and underscoring is provided for
prompting during programming. The 8-button instrument
provides a 
16-character display, and the larger housing of the
16-button instrument allows a 24-character display. An IFP
with 16 pushbuttons and a 24-character display is shown in
Figure 17.3 along with the optional DSS (Direct Station Selection)
AOM (Add-On Module).
The IFP has access to most of the system services offered to a
standard telephone instrument. The following COS 
(Class-of-Service) markings are inherent for the IFP and should not be
assigned from the system:
l Calling Waiting Terminating
0 Calling Number Display
* Called Number Display
0 Call Forwarding

							TL-130500-1001l The originating line selection preferences are based on a
priority system:
- If all three preferences are in effect, the prime line
preference is the first choice.
- If busy, the last line preference (selecting the last line used)
is the second choice.
- And if busy idle line preference is used, any remaining idle
line present on the multi-line set is selected.
The Featurephone can support three different types of 
multiple-line appearances.They are standard, DSS (Direct Station
Selection), and secondary appearance.
Standard Multiple17.5.3 Standard multiple appearances associated with KTSs
Appearance(Key Telephone Systems) have the following capabilities:
0 All appearances can seize the idle line and use it in any
normal fashion.
l Privacy is automatically invoked (although the prime control
line can override the privacy), but the user can choose to
defeat this function, thus allowing other appearances to join in
the call.
l The line can be put on hold, which allows other appearances
to pick up the call, or the line can be put on exclusive hold
where only the invoker can retrieve the call.
DSS Appearances17.5.4 DSS (Direct Station Selection) appearances have the
following capabilities:
l A station with a DSS appearance of another station cannot
control associated line seizing and holding activities.
l The DSS appearance allows line-status monitoring and
single-pushbutton depression to call the appearance directly
for call announce, intercom, or station-to-station calling.
0 Directed call pickup can also be accomplished whenever the
associated monitor LED indicates an unanswered incoming
call. Outgoing calls cannot be made on a DSS appearance.
The following rules govern setting up DSS appearances. Only
four IFP (Integrated Featurephones) can have the optional AOM
(Add-On-Module) operating in the DSS mode.
l Up to 64 standard station instruments may have two DSS
appearances on Featurephones (or 
AOMs). For additional
information, see section 15.0.

							SVR 5210TL-130500-1001* All Featurephone lines can have up to four line/DDSappearances on other 
IFPs (or AOMs)l 16 IFP lines can have up to eight 
line/DSS appearances on
other 
IFPs (or AOMs), and
* Any IFP can also have up to four secondary appearances of
any of its control lines.
Table 17.1 lists the IFP system capacity.
Secondary
17.5.5 Secondary appearances have the following capabilities:
Appearancesl Any Featurephone control line which does not have
appearances on any other set can have multiple appearances
(four maximum) at that Featurephone.
l When using a control line, the Featurephone user can place
that line appearance on hold, select a secondary appearance
line, and place another call.
l If another incoming call occurs at this point, the next idle
secondary appearance line indicates the call and audible
alerting is provided.
l The secondary appearances act like rotary lines appearing on
a KTS instrument, except that the Featurephone does this with
only one directory number.

Featurephonesystem can support:

Analog17.6 The Analog Featurephone interfaces with the system via the
FeaturephonePLCC and the CIP located in PCMUS slots. Place these cards in
adjacent card slots for easier installation and maintenance.
l The PLCC (line circuit card) FB-17254-A provides the
analog channel for both DTMF signaling and voice
communications between the Analog Featurephone and the
system. The analog channel connects to the system via tip
and ring connections to one port of the line card.
NOTE: Once a PLCC is designated for Analog Featurephone
use, only Analog Featurephones can go on that card.
l The CIP (Control Interface Processor) FB-17225-A provides
the digital data link channel connection to the system and
transports all control functions between the Analog
Featurephone and the system.
