At other times in the manual, we discuss prompts that the system displays to you. In these cases, we
enclose the exact wording of the prompt in quotation marks to signify that the system is, in essence,
speaking to you.
• The system prompts, “Enter your password now.”
If the system is actually playing a recording aloud, we enclose the exact wording of the prompt in quotation marks and italics to signify that the system is in actually speaking to you.
• The system says, “You have no more new messages.”
Italics and quotes are also of course used in their normal contexts, that is, for emphasis and to identify
what words are spoken.
• This is called a hot transfer, that is, the system transfers the call without ringing the extension.
There are times when this manual will instruct you to enter a number from within a range of numbers.
In this instance, we use the “~ “ character to indicate the range. For example, 05-01-1~3-001~100 tells
you to enter:
• 05
• 01
• a 1, 2, or 3,
• a three-digit number that falls in the 001 to 100 range.

DX-80 Installation & Maintenance
1. OVERVIEW
The Comdial DX-80 is a fully digital hybrid key telephone system. The DX-80 uses “loop start”
central office (telephone company) line interfaces, and a mix of analog and digital extension ports to
provide office communications and connectivity to the Public Switched Telephone Network (PSTN).
The DX-80 delivers a vast array of office productivity features and telephone use enhancing features,
including Caller Identification (requires telephone company subscription), in the standard package.
Unlike most systems that support Caller ID, the DX-80 supports Caller ID to DX-80 proprietary digital
extensions and to third-party, Caller ID capable analog devices (cordless telephones, etc.)
Although most features are standard, the DX-80 provides for several optional features to further
enhance office communications. Built-in voice processing integration packages include:
• Automated Attendant,
• Four port, Flash-based Voice Mail/Auto Attendant (expandable to 8 ports), and
• Four port, Hard drive-based Voice Mail/Auto Attendant (expandable to 8 ports).
The DX-80 platform allows you to use these voice processing platforms without losing valuable
system port resources.
The DX-80 is comprised of an application configured, expandable Key Service Unit (KSU) platform.
There is one fully-featured Digital Executive Telephone (DET) that delivers access to all system func
tions. The system architecture provides an expandable interface for digital port growth and analog port
growth. The basic configuration supports both device types. (Analog ports might be used for plain old
telephones, fax machines, modems, etc.) The DX-80 is designed to meet the telecommunications
needs of small-to-medium business offices.
1.1 System Technology
The DX-80 incorporates state-of-the-art digital technology for voice switching and call processing,
using Pulse Code Modulation and Time Division Multiplexing (PCM/TDM). The DX-80 is a nonblocking switch, with no loss or degradation of voice signals. The system is stored-program control
and uses a 16-bit, 20 MHz main microprocessor and peripheral devices (extensions and CO lines) in a
distributed processing configuration. Memory consists of 640K bytes of ROM (Read Only Memory)
and 384K bytes of RAM (Random Access Memory). The RAM is lithium battery protected.
The following table shows the available DX-80 equipment.

DX-80 Installation & Maintenance
1.2 Configuration
The Comdial DX-80 platform is comprised of one full-featured key telephone model and two modular
KSUs (Key Service Units). Several modules are available for enhanced system applications and con
figuration expandability.
1.2.1 KSU1 COMPONENTS
The CPM (Central Processor Module) is installed inside of KSU1 to the 408M ribbon cable J4 (also
labeled “To CPM”). The CPM contains:
• Two serial ports,
• Two music ports,
• One control contact (external paging/LBC/gate control),
• One external page equipment interface connection, and
• Socket connectors for the KSU2 (labeled “2nd Cabinet”), MDM, and VP modules (AAM,
7271C, and 7270C).
-

Overview
1.2.3 VOICE PROCESSING MODULES
The DX-80 provides several voice processing (or voice mail) options. The optional voice processors
that you can add to the DX-80 are fixed system resources that do not require peripheral device ports
(analog or digital). This significant advantage means that the DX-80 VP options can be added to any
DX-80 configuration without “port loss” thus eliminating the ill effects of reducing the overall
capacity of the system when the voice processor is connected. Because the DX-80 doesn’t use conven
tional peripheral ports to interface the VPs, we refer to the VP connectivity in terms of “channels.”
• AAM (Automated Attendant Module): The AAM provides four channels for automated
attendant operation only. The AAM is then capable of handling four calls simultaneously.
Callers answered by the AAM are greeted by one of four greetings associated with the DX-80
mode of operation (Day / Evening / Alternate / Temporary). Various other announcements are
also included for caller processing, refer to the DX-80 Technical Manual, Volume II, Programming for further details.
• 7271C (Flash-based, four port VM with Automated Attendant): The 7271 provides four
channels for automated attendant and voice mail operation. The 7271 is equipped to support up
to 100 voice mailboxes and 3.2 hours of message storage (including the various greeting
announcements).
• 7270C (Hard Drive-based, four port VM with Automated Attendant): The 7270C provides
four channels for automated attendant and voice mail operation. The 7270C is equipped to
support up to 2000 voice mailboxes and 150 hours of message storage (including the various
greeting announcements).
-
• 7272 (Four port expansion card): The 7272 is added to the 7271C or 7270C to increase the total
message storage time to 4.5 hours.
All of the these voice processors are connected to the DX-80 CPM via specific interface sockets.
Note: For details on installing the 7271C and 7270C refer to the Corporate Office DX Installation
Instructions, IMI72-005.

1.3 Key Service Unit
The DX-80 Key Service Unit (KSU) is a modular flat-pack design. Two KSU’s (KSU1 and KSU2)
may be equipped to achieve the total system capacity of 16 CO lines, 56 extensions (48 digital and 8
analog) and 8 Voice Processing channels. KSU1 is factory equipped with one 408M, one APM4 and
the CPM. KSU2 is factory equipped with one 408E.
Each KSU is a self-contained cabinet with internal power supply. The power supply AC transformer
voltage switch can be set for either 117vac or 230vac operation. (It is factory set for 117vac oper
ation.) The KSU is designed to be mounted on the wall and is shipped with a wall mounting template.
The compact KSU weighs less than 20 pounds and is UL Listed.

Overview
Figure 1-1 DX-80 Key Service Unit (KSU)
You can remove or reposition three panels installed over various KSU openings to accommodate
exterior connection requirements. You can remove one panel to route a serial cable through the KSU
outer housing for connection of ancillary SMDR equipment. You can remove another panel to route a
serial (NULL Modem) cable through the KSU outer housing for direct connection of a PC for on-site
PC-DBA programming. You can remove or reposition the remaining KSU panel to accommodate
cables entering through the outer housing for connecting station/extension cables or to the MDF.
From the exterior, with covers in place, the KSU1 and KSU2 look identical. However, KSU1 contains
the CPM (system call processing).
1.4 Power Supply
The power supply circuitry of the DX-80 incorporates a linear design AC transformer with a choice of
input voltage. The voltage selector switch is shipped set for 117vac applications; you can also set this
switch for 230vac applications. Since the power supply is linear in design, the output voltage varies
between 21.6vdc and 32vdc depending on load and stability of the input voltage. The output voltage is
delivered to the 408M (in KSU1, 408E in KSU2) for voltage regulation. All system operation and
logic voltages are produced at the 408M/E.

DX-80 Installation & Maintenance
Two fuses are equipped on the power supply board, one for AC input over-voltage protection and one
for DC output over-current protection. A main power switch is accessible when the KSU cover is in
place. In the event battery backup operation is desired the KSU power cord can be connected to a
external (ancillary) UPS (Uninterrupted Power Supply). It is your responsibility to match the battery
requirements/UPS requirement to the specific needs of the equipment owner.
To determine the battery requirement needs and UPS requirement, see Sec tion 1.15, Specifications to
find the current draw and necessary Amp/Hour back up support that the battery/UPS must supply.
1.5 CPM (Central Processor Module)
The CPM module is equipped standard in KSU1. This board contains all circuitry required to control
the fully equipped DX-80. The system uses the CPM to perform all digital voice switching and call
processing data switching.
The CPM has one ribbon cable connector for connection to the KSU1 408M and five (5) connector
sockets for connection of the system built-in modem, voice processor, and second cabinet (KSU2).
Since the CPM comes installed inside of KSU1 the CPM ribbon cable is already in place and con
nected to the KSU1-408M J5 socket. Assuming the orientation of the KSU1 cabinet is installed on the
wall; the two horizontal connector sockets in the upper right corner of the CPM are for the MDM
(Modem Module). The connector socket labeled “2nd Cabinet” is for connection to the KSU2-408E if
that expansion is required. The remaining two connector sockets on the CPM, one at the left side, the
other at the right side are for the voice processor solution. Note: The voice processor solution can be
any of three possible choices: AAM, 7271C, or 7270C.
-
October, ‘03Comdial17
Overview
The CPM also provides the following standard connectors:
• Music Channel 1 - On Hold/Background Music Interface,
• Music Channel 2 - On Hold/Background Music Interface,
• Control Contact (Loud Bell / Door / External Page Control),
• External Paging Equipment Interface,
• RMP Serial Port - for onsite PC-DBA system database programming, and
• SMDR Serial Port - for connection to ancillary SMDR/Call Accounting equipment.
The CPM has two option strap jumpers one for database start-up (J11) and one for music channel one
source (internal/external) selection (JP30).
• J11 Cold Start/Normal—J11 is used to force load database default factory settings. This jumper
will normally never require operation after the initial power up sequence is completed. However
should the need arise to return the site database to the factory settings this jumper is used to
perform a cold start.
• JP30 Internal/External—JP30 is used to select the Music Channel 1 source. The DX-80
provides a synthesized music source for music on hold, in applications where no music source is
available. The synthesized tune is repeated. JP30 is in the “External” position when it ships
from the factory.
1.6 408M (KSU1 Component)
The 408M is the large circuit board that is packaged inside of KSU1. The 408M provides interface for
up to four loop-start CO lines and 8 digital extension ports. Additionally the 408M regulates the 24
volt DC power from the source to produce all required logic voltages and operations voltages. There is
also a Power Failure Port located on the 408M that is connected to the first CO line circuit. Whenever
power fails, this port becomes active with dial tone from the CO line connected to the first CO line
port.

The 408M is equipped with a heartbeat LED that indicates processing activity on the PCB. (The 408M
peripheral processor is operating when the heartbeat LED is flashing.) The KSU1 operation LED
(located next to the power switch) is tied to the 408M heartbeat LED. Therefore, when the LED next
to the power switch is flashing, the 408M is active.
The KSU1-408M has three ribbon cables:
• located at the upper right and oriented in a horizontal position, the J1 cable is used to interface a
COM4 if required to expand the system CO line capacity.
• located at the upper center and oriented in a vertical position, the J4 cable is used to interface the
DX-80 CPM.
• located at the upper center and oriented in a vertical position, the J5 cable connects to the
standard APM4 installed in KSU1.
Each CO line circuit incorporates over-voltage protection, ring detector, loop detector, loop/pulse-dial
relay , current sink circuit, coupling/isolation transformer (impedance 600:600), hybrid circuit, CODEC
& filter, polarity guard circuit and Radio Frequency noise filter.
The fourth CO line port is equipped with CNG Fax Tone Detection circuitry. When programmed as a
“FAX” line, this circuit will automatically engage the F AX Tone detector. If FAX tone is detected, the
system routes the call to the analog port designated as the destination for fax calls.
October, ‘03Comdial19
Overview
Each digital port (connects to Digital Executive Telephones and DSS Consoles) is comprised of a proprietary octal ASIC (Application Specific Integrated Circuit) transceiver. There are three data
channels in operation at each digital port via the octal transceiver. One channel is used for call pro
cessing control of digital terminal functions/operations and two channels are used for the digital voice
channel requirements.
Each digital station interface is protected against circuit wiring shorts by an over-current protection
Polyswitch. The digital station circuit requires only one cable pair to operate and is not polarity sen
sitive.
Physical connection of digital extensions, power failure telephones, and CO lines to the 408M module
is made through convenient RJ-11 connectors along the bottom edge of the module.
-
-
1.7 408E (KSU II Component)
The 408E is very similar to the 408M; however, it is unique to KSU2. The 408E provides interface for
up to 4 loop-start CO lines and 8 digital extension ports. In addition, the 408E regulates the 24-volt
DC power from the source to produce all required logic voltages and operations voltages. There is also
a Power Failure Port located on the 408E that is associated to the first CO line circuit. Whenever
power fails this port becomes active with dial tone from the CO line connected to the first CO line port.
Figure 1-4 KSU2
The 408E is equipped with a heartbeat LED that indicates processing activity on the PCB; the 408E
peripheral processor is operating when the heartbeat LED is flashing. The KSU2 operation LED
(located next to the power switch) is tied to the 408E heartbeat LED, therefore, when the LED next to
the power switch is flashing, the 408E is active.
The KSU2-408E connections are almost identical to those on the 408M (KSU1); the exception is the
long shielded cable used to connect KSU2 to the CPM inside of KSU1. Note: There is no standard
APM4 installed inside of KSU2.
Each CO line circuit incorporates over-voltage protection, ring detector, loop detector, loop/pulse-dial
relay , current sink circuit, coupling/isolation transformer (impedance 600:60 0), hybrid circuit, CODEC
& filter, polarity guard circuit and Radio Frequency noise filter.

1.8 APM4 (Analog Port Module - 4 Circuits)
The APM4 provides four separate analog device ports. This allows the DX-80 to support auxiliary
office equipment such as fax machines, PC/FAX modems, and analog telephones (single line tele
phones). The APM4 generates -30VDC and 20-25Hz, 50V square wave ringing for operation.

The APM4 is equipped with a heartbeat LED that indicates processing activity on the PCB; the APM4
peripheral processor is operating when the heartbeat LED is flashing.
October, ‘03Comdial21
Overview
The APM4 provides DTMF receivers for each analog port. Ancillary analog devices connected to
APM4 analog ports must generate DTMF signaling.
CAUTION
Pulse (rotary-dial) telephones/equipment are not supported.
All connections are via RJ-11 connectors along the bottom edge of the module. KSU1 is delive red with
one APM4 installed on ribbon connector J5 as standard equipment.
APM4’s may be installed on 408M/E-J5 (standard in KSU1:408M-J5), 408M/E-J2, or 408M/E-J3.
CAUTION
It is not possible to install an APM4 on both J2 and J3 on a single 408.
When an APM4 is installed via J2 or J3, it takes the place of DPM8 modules that might be installed in
those locations. Therefore APM4 modules installed using J2 or J3 will reduce the total number of
Digital Port Modules (DPM8) possible.

The DPM8 module expands the DX-80 system capacity of digital ports DET (Digital Executive Telephones) and DSS consoles. Each digital port is comprised of a proprietary octal ASIC transceiver.
There are three data channels in operation at each digital port via the octal transceiver. One channel is
used for call processing control of digital terminal functions/operations and two channels are used for
the digital voice channel requirements. The DPM8 is controlled directly from the 408M/E; therefore,
there is no heartbeat LED located on the DPM8.

1.10 COM4 (Central Office Module - 4 Circuits)
The COM4 module is installed in the dedicated position via J1 of the 408M/E. The COM4 interfaces
four loop-start CO lines. Since one COM4 may be installed in KSU1 and one COM4 may be install ed
in KSU2, you can expand the DX-80 system CO line capacity to support up to 16 CO lines.

The COM4 module is shipped with four mounting stand-of fs used to install the board into the KSU1 or
KSU2. Five RJ11 jacks are provided along the bottom edge of the COM4 module for connection of
one power failure telephone and the four CO lines.
CO lines are terminated at the site by the telephone company at a point of interface called the Demarcation (Demarc). When ordering CO lines for the site, request termination on RJ11 type jacks. Doing
so allows you to easily extend the CO lines to the COM4 RJ11 connector (one CO line per jack and
connector).
Each CO line circuit incorporates over-voltage protection, ring detector, loop detector, loop/pulse-dial
relay , current sink circuit, coupling/isolation transformer (impedance 600:60 0), hybrid circuit, CODEC
& filter, polarity guard circuit, and Radio Frequency noise filter.
The fourth CO line port is equipped with CNG Fax Tone Detection circuitry. When programmed as a

DX-80 Installation & Maintenance
1.11 MDM (Modem Module)
The 7249 Modem Module is a self-contained integrated modem unit that is installed at JP5 and JP6 in
the upper right corner of the CPM. The integrated MDM allows you to access the system pro
gramming and remote maintenance utilities from an off-site location (password verification is
required).
Figure 1-8 MDM (Modem Module)
-
When the MDM is installed, you can program the system remotely using PC-DBA. Note: PC-DBA is
included in the utilities CD DXUIILCD shipped with every new system. Or, you can obtain PC-DBA
free of charge at the Comdial Web site, www.comdial.com.
You can service the system, using PC-DBA and a modem in your PC, to place a call to the site where
the DX-80 is installed. Note: If one of the voice processing systems are installed, routing to the
modem extension is automated. Otherwise, the person who answers this data call must transfer the
call to extension 199. Once the modems have established the data connection, you can begin servicing
the switch.
CAUTION
The MDM default extension number is 199. This number can be
changed and therefore may be different for some DX-80 systems.

Overview
1.12 AAM (Automated Attendant Module)
The Automated Attendant Module is a self contained integrated module that enables automatic
answering of selected CO lines and a single-level menu for greeting callers and routing them to DX-80
system destinations. The AAM can handle all call traffic or act as a backup to the primary answering
system attendant.
Figure 1-9 AAM (Automated Attendant Module)
The AAM is installed at JP3 and JP4 of the CPM (centered above the board).
The AAM provides 10 announcements for the various modes of system/action operation: Day
Greeting, Alt Greeting, Night Greeting, Waiting Message, Invalid Message, Busy Message, No
Answer Message, Goodbye Message, Inquiry Message, and Temporary Message.
1.13 DET (Digital Executive Telephone)
The DX-80 has one model digital telephone called the Digital Executive Telephone. The DET provides:
• a half-duplex speakerphone for hands-free conversations,
• a two-row by sixteen column (32-character), dot-matrix, supertwist, Liquid Crystal Display
(LCD), and
• three interactive buttons to enhance system feature operation.
The supertwist LCD eliminates the need for contrast adjustment, and enhances clarity of displayed
data using an angled viewing position. Since the DX-80 includes Caller ID (CID) as a standard
feature, the LCD also provides every designated ringing extension with CID data for incoming CO line
calls. Note: CID requires a subscription from the servicing telephone company.

DX-80 Installation & Maintenance
The display also provides a visual reference to call progress and call duration, as well as time and date
information. The display enables the user to send and receive visual advisory and callback messages.
Users may select from six pre-programmed messages (i.e., “IN A MEETING,” “OUT OF OFFICE”),
or they may create a custom message. Callers from other DETs to an extension with a message active
will receive the visual advisory message on their LCD display.
Each digital speakerphone has 30 programmable Feature Buttons to aid the user by providing direct
access to system features and resources. There are also three interactive buttons and 8 fixed function
buttons. Note: The volume button bar represents two operations: volume up and volume down.
Each DET is equipped standard with a 2.5 millimeter headset jack. Users can toggle their speakerphone operation in and out of a special “headset mode”. This mode allows the user to easily activate
the headset jack via the ON/OFF button as an alternative to using the speakerphone. Thus, headset
mode is easily enabled or disabled so that users can quickly select between use of the headset or speak
erphone operations. Note: The DET must be idle to change this setting.
Each speakerphone is also equipped with a status lamp to aid in user operations. The lamp is dual
color (red / green) and indicates various modes of operation, such as messages/voice messages
waiting, incoming calls - distinctive for CO and intercom, in-use indication for speakerphone mode,
headset mode, etc.

Overview
1.14 DSS (Direct Station Selection) Console
The DSS console is a digitally interfaced component of the DX-80. It connects to the system via any
available digital port (408M/E or DPM8 digital port). The DSS is equipped with 60 programmable
buttons. Twelve of these buttons are intended for features code storage only and do not have LED
indications associated with them. Forty eight buttons are equipped with dual color (red / green) LEDs
and may be assigned any system feature code or directory number; these buttons may be assigned for
either system features operations or CO line access operations.
You can mount the DSS console in one of two positions: lower profile desk position and wall mounted
position. DSS consoles are programmed to operate with an associated speakerphone. You can assign
up to four DSS consoles per speakerphone. The maximum number of DSS consol es supported by the
DX-80 is 12. Each equipped DSS console requires one digital port, therefore the total number (system
capacity) of speakerphones possible is reduced by one for each DSS console installed.
