B.1
Hardware overview/installation
IVX C-Class starts out as a three-line, six-station, two-analog-portsystem, but can expand to handle as
many as six lines and 12 digital stations (and two analog ports).
Base Cabinet I
The wall-mounted Base Cabinet I measures 81/2″W 11″H 3″D, and is designed for easy
installation and easy component access. It houses the Memory Module and Main Board (3x6x2), one
multi-purpose serial port, a MOH connector and another port card slot — which accepts an additional
360 port card.
Main board
The main board combines leading-edge hardware components — including a Motorola♦ColdFire♦
processor and Texas Instruments♦DSP structure — along with proprietary operating system software.
The board provides: system control of the Memory Module and port cards1; a standard RS-232C DB9
serial port; a built-in 33.6 Kbps modem for remote access; an external paging-device interface; and
MOH interface. The C-Class main board has a three-line, six-digital station, two-analog port configuration.
The CO line ports support standard CO and Centrex loop-start lines; ground-start CO lines are not
supported. The analog ports provide a standard 24-volt,two-wire connection to fax machines, analog
phones, and modems. Only one analog device can be connected to each analog station port.
Port card
There is only one port card type, 360, available for IVX C-Class.1The 360 port card is equipped with a
standard female Amphenol connector for easy wiring to a standard 66 or 110 block. This C-Class port
card cannot be used on any other ESI phone system. The 360 port card provides circuits to connect up
to three loop-start CO lines and six Digital Feature Phones.
Note: The system must contain a 360 portcard to access both conference bridges.
Wall-mount transformer
The System Cabinet requires a 1.25-amp transformer (supplied).
Memory Module
The Memory Module2consists of a CompactFlash®card. The memory module on IVX C-Class
contains all system programming and configuration data, including pre-loaded voice prompts.
1Generation II only. IVX C-Class Generation I systems are configured 6x12x2 and don’t support additional port cards.
2Memory Modules are packaged separately and are mounted in the cabinet during installation.

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.

Here is the layout of a typical IVX C-Class installation:
IVX C-Class typical installation

Hardware overview/installation IVX C-Class with voice mail: Installation Manual
B.6
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 IVX.
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.
Replacingthe Memory Module erases all its configuration data and custom recordings.
(Prompts stay intact, however.)

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 the 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 (see “UPS,”
below) 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 (UPS, or
“battery back-up”) is STRONGLY recommended. A UPS rated for 200 VA will provide approximately
two hours of uninterrupted service for an IVX C-Class system.
Note: The remaining information under “UPS” comes from Technical Update #216.
Most people have heard about UPSs, but seem to think that there is just one kind of device that goes by
that name. In fact, there are several different major designs in use by today’s major UPS manufacturers.
These makers share much of the blame for confusing UPSs’ end users by, far too often, lumping
different designs under the “UPS” name.
UPSs can first be broken down into system types:
• Stand-by — A very simple design that affects power only when either a lag/brownout occurs below,
or a spike/surge occurs above, a certain threshold. When either occurs, the unit trips — i.e., goes into
battery mode. This "cleans" the voltage and helps to keep any load safe. Industry average "trip" times
are 2–8 ms. No other filtration of AC power is performed.
• Line interactive — Constantly monitors inbound voltages, and uses special circuitry to boost low
voltages and clamp high voltages without having to use the batteries. Indeed, the batteries are used
only if the input voltage drops below acceptable levels (typically about 12% below normal), goes out
completely or rises to dangerous levels (typically about 14% above normal) at which components will
be damaged if line voltage is not removed. Industry average transfer time is 1–3 ms. (If voltage stays
within its normalwindow, this unit continues to pass voltage, unaltered, from the wall.)
• On-line (or full on-line) — Constantly filters the power and performs a function known as double
conversion (AC to DC to AC). This assures that the load — in this case, phone equipment — will
receive not only uninterrupted, true sine wave output butalso the cleanest, steadiest power possible
throughout any foreseeable power disruptions or voltage irregularities. According to industry specs, it

Hardware overview/installation IVX C-Class with voice mail: Installation Manual
B.8
is not unusual for these types of units to be able to regulate utility power, even when it drops to 27%
below or rises to 33% above normal, all without using their batteries.
From this point, UPSs can be further broken down by inverter types, which determine output. These are:
• Square wave.
• Modified sine wave (or quasi sine wave).
• Sine wave.
Most devices with wall-mounted chargers, such as cordless drills or screwdrivers, can behave erratically
— sometimes not allowing the charge circuit to engage at all — when operating with modified sine or
square wave inverters. Small wall-based transformer-style power supplies, similar to those ESI phone
systems use, can experience overheating problems with modified sine or square wave outputs, which
occur while some UPSs are operating in battery mode. This overheating could eventually cause
damage to the power supplies; and, in time, the damage could cause a spike through the phone system
— seriously damaging some of the static-sensitive components inside the casing.
While the true sine wave UPS output power curve smoothly increases to its peak, then smoothly
decreases (allowing connected loads and equipment to operate the same as they would from utility
supplied wall power), the modified sine wave and square wave UPS output power curve will shoot
straight up, level off at peak voltage and then drop straight down. Additionally troublesome is that the
modified sine wave sits at zero voltage for a short period during the transition to or from batteries —
which is the main difference between it and the square wave output of some UPS. Please note that this
short interval during which the modified sine wave UPS sits at zero voltage can directly affect the
transfer time of the UPS and could, theoretically, be enough to cause the phone equipment to reset or
even “freeze.”
Though it is hard to predict exactly when different ESI systems will have problems with modified sine
wave or square waveform UPSs (meaning during a power failure event or the recovery from one), it’s
fair to assume that a problem will eventually arise from the use of such UPSs. Therefore, ESI
recommends that only true sine wave output UPSs provide backup power to our phone systems
and equipment.
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 with voice mail: Installation Manual Hardware overview/installation
B.9
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), nordoes it support CO ring
through the port.

Hardware overview/installation IVX C-Class with voice mail: Installation Manual
B.10
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. The connector closest to the wall is the first port card
(which is the main board on the C-Class).
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 six 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 (“Worksheet,” page B.13).
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.
