General description
Welcome to IVX®C-Class (IVX stands for Integrated Voice Exchange). It offers the small business an
all-in-one phone system including not only phone service but also ESI’s Integrated Answering Machine™
— which allows up to two people to leave messages simultaneously and accepts a total of 30 minutes of
voice message storage.
The IVX C-Class1system is housed in a surprisingly small case that is wall-mounted in the telephone
equipment room. An external, wall-mounted power transformer powers the system.
Telephone system features
IVX C-Class is configured to accept six lines, 12 digital stations, and two analog devices.
• Impressive capacity — Handles six CO lines and up to 12 stations.
• ESI Feature Phones — Compact and stylish, yet rugged, the 24-Key Digital Feature Phone includes
a high-quality speakerphone, large and informative multi-functional display and a specially designed
key layout with several dedicated keys to minimize or eliminate the need to memorize codes. ESI
also offers the 12-Key Digital Feature Phone with similar design and basic functions (see page B.1).
At least one 24-Key Digital Feature Phone must be purchased with each C-Class system.
• Extensive help — ESI’s Verbal User Guide™uses spoken and displayed help prompts to help
everyone from the Installer through the Administrator down to the least experienced end user.
Easily accessible with one press of the PROG/HELP key. You may also go to www.esiusers.com
for detailed online help.
• Intelligent Caller ID — Allows one-touch automatic message return.2
• Call waiting — Includes helpful display, showing both calls’ Caller ID information, and easy one-key
toggling between calls.
• Conference calling — Includes two conference bridges, and a conference may contain up to four
parties, so IVX C-Class can support two conferences of four parties each. Analog phones on the
system also may be parts of conferences.
• Esi-Dex™speed-dialing — Calls any number using three separate lists (personal, station, and
system); uses Caller ID information or direct keypad entries.
• Dedicated overhead paging interface — Allows for external paging through overhead speakers or
multi-zone paging units (amplification required).
• 911 alert — Provides immediate line access if any station with line access dials 9 1 1 to report
an emergency; sends a message via the serial port indicating the start date, time, station number and
end-time of the 911; also sounds a warning tone at the operator station and displays, for example:
911 CALL FROM
X102 JOHN JAMES
• Status indicator lamp — Indicates three conditions of the 24-Key Digital Feature Phone: off-hook,
ringing, and new voice mail message.
1Also known as IVX 20c.
2This and all other references to Caller ID service within this manual assume the end-user organization subscribes to Caller ID
service from its telephone service provider.

General description IVX C-Class Installation Manual
A.2
Integrated Answering Machine features
• Two built-in Integrated Answering Machine ports (or “channels”) — These are in addition to
the up-to-20 possible call-processing ports; thus, you may build the system to its maximum for call-
handling without having to balance voice messaging needs versus call-handling needs.
• Highest-grade voice quality (64-kilobit/second sampling) for storage of voice messages.
IVX C-Class with Integrated Answering Machine offers 30 minutes of voice message storage.
• Records up to two simultaneous calls —When a message is left, the message indicator on the 24-
Key Feature Phone will light. Messages can be retrieved by any authorized 24-Key Feature Phone or
remotely from an off-premises location. The system can also be programmed to either call an off-
premises number or commercial network to deliver messages.
• Four message-on-hold (MOH) recordings — Three prerecorded and one live-entry.
• Message Recycle Bin (undelete) — Remembers, and can restore, the Integrated Answering
Machine’s 10 most recently deleted messages.

IVX C-Class Installation Manual Hardware overview/installation
B.1
Hardware overview/installation
IVX C-Class consists of a system cabinet that accepts six lines, 12 digital stations, two analog ports,
and 30 minutes of voice message storage.
System cabinet
The wall-mounted system cabinet measures 81/2″W × 11″H × 3″D, and is designed for easy
installation and easy component access. It houses a Memory Module and main board. The system
includes a 33.6 Kbps modem used by ESI technicians for remote diagnostics.
Main board
The main board combines leading-edge hardware components — including a Motorola®ColdFire®
processor and DSP structure — along with proprietary operating system software. The board provides:
system control of the Memory Module (CompactFlash®); six CO line interfaces; 12 digital station
interfaces; two analog ports; a standard RS-232C DB9 serial port; a built-in 33.6 Kbs modem for remote
access by ESI technicians; an external paging-device interface; and an MOH interface.
Wall-mount transformer
The system cabinet requires a 1.25-amp transformer (supplied).
Memory Module
The Memory Module1consists of a CompactFlash card. It contains all system programming and
configuration data, including pre-loaded voice prompts, and provides 30 minutes of voice storage.
Phone models
IVX C-Class supports two phone models:
• 24-Key Digital Feature Phone — Two-line, 32-character display; 12 programmable feature keys;
equipped with speakerphone
• 12-Key Digital Feature Phone— One-line, 16-character display; nine programmable feature keys.
Each model connects to the cabinet via standard two-wire twisted pair.
Note: Use the wall hook located under the handset when the phone is in the most upright position to keep the
handset in place.
Phone overlays
Each ESI Feature Phone comes with one overlay for the programmable feature keys. To order
additional overlays, visit the DESI™ Web site at www.desi.com. You can also download the free
Windows-based software, DESI Lite, which allows you to print on the overlays. For assistance with

Cautions
Important: This information complies with the requirements of Underwriters’ Laboratories (UL) and UL
Standard 60950.
When using this telephone equipment, always exercise basic safety precautions in order to minimize the
risk of fire, electric shock or injury to persons. Before proceeding, please read the following:
• The airflow vents on the IVX case must be free of obstruction for proper cooling. Similarly, do not
install the cabinet in areas of extreme heat or improper ventilation. Never insert objects of any kind
through the ventilation slots on the system cabinet; doing so may result in contact with dangerous
voltages — or cause an electrical short capable of producing fire or shock.
• Do not use liquids or aerosols to clean any IVX equipment; rather, use a cloth that is only
slightly damp.
• The IVX telephone/voice-mail system contains no components that are serviceable by either
non-Resellers or non-manufacturer technicians. All service must be referred to the Reseller for
further handling.
• To reduce the risk of fire, use only 26 AWG or better telecom wire.
Power supply
Always disconnect the power supply and telephone lines from the system cabinet before opening the
case for service or component disassembly or replacement.
Heed all warnings and instructions in documentation or marked on the cabinet or peripheral equipment.
Note: If necessary, review “Wall-mount transformer” (page B.1) for information on the type of power supply for
the IVX C-Class system.
Fuse
Contact the factory before attempting to replace the fuse. The fuse is marked with “F1” and is located at
the top (when the system is installed on the wall) of the motherboard.
Battery
“Caution: There is a danger of explosion if the onboard lithium battery is incorrectly replaced. Replace only
with Ray-O-Vac®BR1225 (or equivalent). Dispose of used batteries according to the battery
manufacturer’s instructions.”

Hardware installation
Site location
As with most electronic equipment, the environmental considerations for this site need to observe good
common sense. Provide a dry, clean, and accessible area.
Locate space in the telephone equipment room, which will provide easy connection to the 66 blocks and
110VAC power. The location should be no further than 1,000 feet from the farthest station.
Ambient room temperature must be 400 –800(F.), and relative humidity no higher than 90%.
Note: Do not place the equipment or station cabling runs near high voltage electrical equipment or electrical
lines susceptible to high voltage surges from air conditioner compressors, etc.
The system and supporting components should be mounted to a half-inch (or thicker) plywood backboard.
IVX C-Class typical installation

IVX C-Class Installation Manual Hardware overview/installation
B.5
Opening the cabinet
The lid on all cabinets is held in place by two tabs that rest in slots in the bottom of
the case, and a release tab that snaps into an opening in the top-center of the
cabinet and is secured by a retaining screw.
To remove the lid:
1. Remove the retaining screw and depress the release tab at the top of
the cabinet.
2. Rock the lid back from the top.
3. Lift and pull the lid free from the slots in the bottom of the cabinet.
Mounting the cabinet
Use three #8 hex-head screws. Note the position of the three mounting holes in the IVX cabinet.
1. Screw in the top screw to the backboard (at least half-inch thick
plywood) leaving about one-eighth-inch clearance between the
screw head and the plywood.
2. Hang the unit using the keyhole at the top of the case.
3. Level the unit and install the bottom two screws.
Attach the power transformer to the wall, allowing sufficient length in
both cords to reach the power connector on the upper right side of
the cabinet and to reach a UPS or a dedicated 110 VAC outlet.
Memory Module
Note: The Memory Module has a proprietary formatting scheme — do not attempt to install a non-ESI
CompactFlash. Contact ESI for a replacement Memory Module, if needed.
Adding or replacing the Memory Module will require that the system be powered down.
Replacing the Memory Module erases all its configuration data and custom recordings.
(Prompts stay intact, however.)

Hardware overview/installation IVX C-Class Installation Manual
B.6
Grounding instructions
System grounding (supplemental ground) is as follows:
• The conductor wires can be no smaller than the ungrounded branch-circuit supply conductors
(usually 16-gauge or larger).
• Acceptable wire: bare or covered with green (or green-and-yellow-striped) jacket.
• Conductors (and power receptacles) shall connect to earth ground at the service equipment (usually
a cold water pipe or copper ground rod).
• The supplemental ground must: be used regardless of power cord ground, be connected to the
ground lug on the bottom of the IVX cabinet, and retain ground connection when IVX power supply
module is unplugged.
Note: IVX C-Class system lines are protected against a 10 KV surge only if the earth ground procedures
described above are followed.
Power
The system cabinet requires a 120 VAC outlet (if possible, a dedicated outlet). Use only the Class-2
power supply module provided. A clean, isolated power source in conjunction with a UPS is
STRONGLY recommended. The system draws a maximum of 25 watts.
If AC power is interrupted, the system will drop all connections. When power is restored, the system
will resume normal operation in approximately one minute, having retained its full programming and
clock setting.
UPS
For system protection and to maintain uninterrupted operation, an uninterruptible power supply is
STRONGLY recommended. A UPS rated for 200 VA will provide approximately two hours of
uninterrupted service for an IVX C-Class system.
LED functions
The unit's various LEDs are designed to provide visual feedback as follows:
Power LED
The Power LED is located on the top-right side of the cabinet and is illuminated when power is being
applied to the system. This LED blinks periodically to indicate that the main processor is operational.
Memory Transfer LED
This LED is located inside the cabinet in the center of the main board. It serves as a diagnostic aid by
flashing as data is transferred to and from the Memory Module.

IVX C-Class Installation Manual Hardware overview/installation
B.7
MOH port
The MOH (messages-, or music-, on-hold) connector on the upper right side of the cabinet is a standard
1/8″monophonic mini-jack, used for loading custom MOH recordings or for playing live music-on-hold
from an external source such as a radio or CD player.
Maintenance/SMDR serial port
The Maintenance/SMDR port is a standard DB9 serial connector located on the side of the cabinet.
Use a standard shielded serial cable, DB9-to-DB9, for printer-to-computer (this is usually male-to-female).
Note: The maximum distance from the cabinet is 100 ft.
The output from the Maintenance/SMDR port is, 8 data bits, 1 stop bit, and no parity. The pinout is:
Data Transmit Pin 2
Receive Pin 3
Ground Pin 5
Range: Programmable for 300, 1,200, 2,400, 4,800, 9,600, 19,200, or 38,400 bps.
Default: 38.4K.
SMDR
The IVX C-Class system continuously outputs real-time SMDR call records to the port.
Note: The system will buffer up to 1000 SMDR records (80 KB) in non-volatile memory (CompactFlash) when
the maintenance port is in use for programming or uploading. When the buffer reaches capacity, the
oldest records are discarded.
External paging device connection
A dry contact overhead-paging device can be connected to the system through the port card's 66 block.
The overhead paging port is fixed (located on the main board) as extension 199 for programming
purposes and user access.
Audio connection
The audio pair is connected to the 66 block at terminal 33 and 34. The pair’s impedance is 600 ohms.
Dry contact control
The manner in which the dry contact pair is punched down on the 66 block sets the pair as normally
open (sending a page to the port will close the contacts) or normally closed (sending a page to the port
will open the contacts).
Connect the dry contact pair of the device to IVX as follows:
• Terminals 35 and 36 to provide normally open operation
or
• Terminals 35 and 37 to provide normally closed operation.
The port can be used with zone paging units.
Note: The port doesn’t support talk-back paging (which requires a CO port), nor does it support CO ring
through the port.

Hardware overview/installation IVX C-Class Installation Manual
B.8
Amphenol cable connections
Connect a standard 66 block using a male 50-pin amphenol cable to the port card’s female connector
located on the bottom-right side of the cabinet.
CO line connection
Local loop
The IVX C-Class system's advanced CO line circuitry provides for open loop detection and the system’s
built-in Caller ID interface.
Note: Observe correct order of connection to preserve proper rotary hunting of the CO lines.
Station connection
The first 12 pairs on the amphenol are station ports.
All stations are connected using a single pair. Each port position is pre-numbered and fixed as indicated
in the 66 Block Wiring Diagram.
Note: The station runs can be up to 1,000 ft.
Digital stations
The digital station wiring is not polarity-sensitive. Only one phone can be connected per digital port.
Analog ports
The analog ports do not require that tip-and-ring polarity be observed. The analog ports can be used for
2500 type sets or for devices such as fax machines, cordless phones, etc., that can be connected via a
normal tip-and-ring pair. Each analog port will support only a single analog device.
