							System Description
Consoles
The 524consoles house a 20-character fluorescent display, line status indicators, line and call processing
keys, a common audible transducer, an electronic voice network, and a microcomputer to control their
operation. The factory-provided hearing aid compatible handset utilizes an electret (carbon clone) element.
Tone Commander consoles are designed to provide superior operating capabilities in any working
environment.

The vacuum fluorescent display is adjustable, can be seen from almost any angle, and is immune to
overhead lighting glare. This allows displayed information to be viewed from greater distances than
with nonfluorescent versions.

Whenever possible, call processing routines are accomplished with single keystrokes.

Multiple indicators are used to improve status recognition.
Following is a description of the keys, indicators, and connectors on the console:

Display– 20 character alphanumeric display gives information about calls ringing at the console, and
is used during console programming. A time of day clock is displayed when the console is idle.

Line Keys– when a line key is pressed, the console network is connected to the selected line. If a
second line key is pressed, the first line is automatically put on hold and the second line is accessed
(Auto Hold). Spare line keys may be used to access paging systems.

Hold Lamps (Hsymbol) – indicate hold and hold recall states of the lines.

Line Lamps(telephone symbol) – indicate busy and ringing states of the lines.

DSS Keys– when the console is in normal mode, the 24 DSS keys automatically dial programmable
sequences when pressed. These keys are also used during programming to enter name displays.
They are normally used to autodial the station associated with the key.

Station Status Lamps– indicate busy and ringing states for the stations.


HOLD Key– when the console is on an active line and the hold key is pressed, a hold bridge is
placed across the selected line and the console network is released from the connection.


TRANSFER Key– when the transfer key is pressed, a hookflash (momentary open loop) is
generated on the selected line. This allows the attendant to transfer calls or access special features
of the telephone system.


RELEASE Key– when the console is on a line and the release key is pressed, the console network
is released from the connection, the line becomes idle, and its lamp will turn off.


ANSWER Key – automatically seizes a call appearing in the alphanumeric display.


RING DELAY Key– used to enter/exit ring delay check mode or ring delay programming mode.


PICK UP Key– used to answer a ringing station not appearing in the alphanumeric display.


VOL Keys– used to adjust the console ringer volume.


Dial Pad– generates DTMF signaling on a selected line. Dial pad keys are also used to enter
console programming values.
Attendant Console Cabling
Three pair, #24 gauge, twisted cable is required. The two cable runs should not exceed 500 feet each. One
pair on the voice/data cable is analog voice. The two remaining pairs transmit proprietary protocol at 1200
baud using the RS-422 standard.
13-102408 Rev. HPage 43
Tone Commander 524 Installation Instructions 
						

							The second cable uses all three pairs to provide power to the console.
Central Processing Unit (CPU)
The Central Processing Unit is a wall mounted device which contains the power supply,
microprocessor-based control logic, 5 line circuits, 24 station circuits, dial tone detect circuits, two console
data link circuits, two DTMF dialer circuits, and a Music On Hold input circuit. System memory is retained
during power failure.
External connections to the Central Processing Unit are made by using 50 pin Amphenol connectors. Music
on hold may be optionally connected to an RCA-type audio jack on the CPU. Modular console jacks on the
main circuit board are provided for testing and programming.
System Features
Dual Console Capability
The CPU can support two console positions. Line and station appearances are identical at each console
(square line configuration). Holding status is indicated at both console positions. Special line key options
(paging access) appear at both console positions when programmed. Certain operating features such as
Queue Priority, Ringing Type, Line Privacy, and Answer Use may be programmed on per console basis.
Skinny Wire Console Connection
Six pair cabling is required between each console and the CPU. Three pair are used for data and voice,
and three pair are used for power. Two 6 conductor modular jacks are located at the rear of the console,
one for voice/data and one for power.
Installer/User Programmability
Both installer and user can program the system from the front panel of the console. The installer programs
system configuration options, line programmable features, and special feature key assignments. The user
can program customized features such as ring delays, Direct Station Selection (DSS) dialing, autodialing
numbers, line/station name identification, Hold Recall Time, Queue Priority, etc.
Ringing Queue
Calls to be answered by a console are placed in queue. The nature of the queue (i.e. station calls only,
stations before lines, lines before station, or first in-first out FIFO) is selectable on a per console basis.
Distinctive Ringing Detection
Used in conjunction with the Distinctive Ringing capability provided by the serving Centrex C.O. or PABX,
unanswered station calls can be displayed alphanumerically or ignored, depending on the type of ringing.
Paging Interface
The Tone Commander PA-24 Paging/Chime Module or an equivalent external, battery-feed paging adapter
can be connected to any line key programmed as a Page key. When this is done, the selected line position
will be conditioned to operate with either 48 VDC or 24 VDC battery feed circuits, the latter being typical of
most paging adapters. The PA-24 can be powered directly from the 524 CPU.
Page 4413-102408 Rev. H
Tone Commander 524 Installation Instructions 
						

							Music On Hold Interface
Each line can be set to provide audio programming while in a holding state. Access is via block terminals or
phono jack. An input gain control is provided to adjust programming to the desired level.
Console Test Jacks
Six pin modular jacks for both voice/data and power are provided for two console positions. These jacks
are intended to provide a quick means to verify console-to-CPU operating integrity.
Console Features
Distinctive Audible Signaling
The system recognizes normal or distinctive ringing from the serving central office/PABX and responds with
differentiated audible signaling. The console also signals the attendant when held lines are recalling, calls
to stations have gone unanswered for a predetermined period of time, confirming programming
entries/storage, or when errors have been made involving operation or programming. Incoming call audible
signaling is abbreviated whenever the attendant is active on a line.
Ring Delay
Each line and station appearing on a console can be individually programmed to ring at the console
immediately, after a predetermined number of ringing cycles, or never ring at the console. The Ring Delay
feature does not affect ringing at the station.
Alphanumeric Display
Calls to be answered are displayed with a three character prefix which indicates the nature of the call (i.e.
INC, RCL, HLD, CMP, etc.), followed by the line or station number, then the number of calls in queue. Line
or station numbers can be replaced with 14 character names as desired. The display is also used to view
programming options and confirm all entries.
Single-key Answering
Calls to lines or stations that are to be answered by the attendant are alphanumerically displayed according
to the selected ringing queue. Depressing the Answer key seizes the call displayed.
Dial Pad DTMF Dialing
The 524 console is equipped with a standard 12 button dial pad. The various tones will persist as long as
the desired key is pressed iffastdialing speed (10 digits/sec.) has been selected during configuration
programming. Ifslowspeed (6 digits/sec.) has been selected, digits are buffered and sent with a tone on
period of 80 ms, and 80ms between digits to guarantee minimum tone periods for slow central offices.
Time of Day
The alphanumeric display shows the time of day whenever the console is idle.
Variable Ringer Volume
VOL

and VOL
keys are provided on the face of the console to adjust the level of the audible ringer in
accordance with the operating environment. A bar graph display is provided for referencing.

							Handset Jack Connection
A four pin modular jack is located on the left side of the console.
Handset
A K-type, hearing aid compatible handset with electret transmitter is provided with the console.
Direct Line Access
Each line is accessible via a dedicated key for answering, holding, transferring and originating calls.
I-Use Indication
A fluttering line status lamp identifies the particular line to which the handset or headset is connected.
Line Privacy
Individual lines may be programmed to exclude third party access to ongoing calls by the attendant.
Line Hold
Each line can be placed in a Hard Hold condition at the console. Music on Hold, if optioned and a source
provided, is connected to the line. A line on Hard Hold can be released from the console when bridged by
either a telephone set or another console. A valid loop interruption from the central office will also release
the line.
Line Hold Indication
A flashing Line Hold lampHindicates a line placed on hold by the attendant. A steadyHindication
identifies a line placed on hold at the companion console.
Automatic Line Hold
Active lines may automatically be placed on Hard Hold by either depressing another line key or the
Answer key while a call is being displayed.
Hold Recall
A call placed on Hold for longer than a predetermined time period is identified with a unique audible ringing.
TheHindication for the affected line is also unique.
Line Transfer
Calls originating or answered at the console can be placed in a Soft Hold or Consultation Hold condition
at the serving Centrex Central Office/PABX by hookflashing (pressing the transfer key), then dialing the
desired station number.
Page Key (optional)
Any line key can be programmed to be a Page key. When this is done, the selected key position is
automatically assigned line privacy, answer use exclusion, and automatic line hold exclusion.
Pressing the Page key places the currently selected line on hold and connects the attendant to the paging
system.

Tone Commander 524 Installation Instructions 
						

							Autodialing
Any spare DSS key can be used for autodialing while on an active line.
Busy Lamp Field (BLF)
Each station connected to the console system has a dedicated lamp that indicates its status (i.e. idle,
off-hook, or ringing).
Direct Station Selection (DSS)
DSS keys provide quick and efficient transfer of all calls. Each key position must be programmed with the
appropriate dialing instructions - typically a Flash, Dial Tone Detect, then the station digits.The DSS feature
is available only for stations that are monitored by the 524.
Station Recalls
Calls transferred by a DSS key to idle stations which go unanswered for a predetermined period, re-ring
and are displayed at the console.
Station Call Pickup
Unanswered calls that are indicated in the busy lamp field but not in the alphanumeric display can be
answered at any time by depressing the Pickup key, then the desired DSS key.
Telco/PABX Requirements
Certain signaling protocols and features of the telco/PABX host are required for proper operation.
Required System Configuration
The C.O. and station lines must originate from either the same Centrex Common Block or the same PABX
tenant partition.
Required Signaling Protocols
1.-42.5 to -56.5 VDC C.O. battery
2.40 to 130 Vrms @ 20 or 30 Hz Ring Generator
3.Loop start
4.Disconnect Supervision for Abandoned Calls
The central office opens Tip and Ring (removes the source of DC voltage) for a brief interval whenever the
calling party disconnects prior to the called party. This protocol is required to support automatic hold
release.
Required Attendant Line Features
1.Touch Tone Dialing– all manual or auto dialing from the 524 console is DTMF.
2.Station Call Transfer– to use the Transfer key or the programmable FLASH command while
autodialing to transfer incoming calls. Typically, inbound calls are transferred by hookflashing,
receiving new dial tone, then dialing the desired station. In most instances call transferring is limited to
stations within the same PABX or Centrex Common Block.
13-102408 Rev. HPage 47
Tone Commander 524 Installation Instructions 
						

							CAUTION– In some host systems, hookflashing automatically transfers inbound calls to a proprietary
attendant position. This feature is often referred to as Call Transfer-Attendant and is not
compatible with Tone Commander console operation.
3.Directed Call Pickup, NonBarge-In– to retrieve unanswered station calls showing in the alphanumeric
display.
Optional Line Features
Dedicated nonhunting attendant lines– used to retrieve unanswered station calls. It is recommended
that (1) nonhunting line per console be provided for this purpose. This will allow dedicated access,
unaffected by inbound traffic, and prevent call collisions (glare). Refer to the Answer Use line feature
described on page 36.
Required Station Feature
Call Pickup– all station lines monitored by the 524 must be assigned to a Call Pickup Group.
IMPORTANT– Call Forward - No Answer isnotrecommended because it conflicts with, and may defeat,
the operation of the 524 Ring Delay and Name Display features.
Optional Station/Line Features
Additional features may be optioned as required.
IMPORTANT– Whenever the Call Waiting feature is invoked on a busy station, such a call will not recall to
the console. Ring Delay and Recall Ring parameters do not apply because the station in
question is in a busy rather than a ringing state.
Compatibility With Other Products
Music On Hold
The Music On Hold input on the 524 CPU is compatible with telco feed, low impedance, balanced
subscriber background music services such as Muzak. Always terminate such a line with a resistor equal to
the characteristic impedance of the line, usually 600 ohms. AM/FM tuner and tape player outputs are
typically unbalanced high impedance music sources which require shielded cable. Characteristic
impedances vary from 600 to 50K ohms.
Paging Access
The 524 is compatible with any paging system that provides a Tip/Ring talk battery feed circuit. Such
circuits can be cross connected to any spare line position on the console.
Tone Commanders PA-24 Paging/Chime Module interfaces any paging amplifier to the 524, and derives
power from the 524 CPU.
Voice Mail
Most on-premise voice mail systems are compatible with the 524 system. Voice mail is usually accessed
from a spare DSS key.
