IMPORTANT SAFETY INSTRUCTIONS
CHAPTER 1 INTRODUCTION
Important Safety Instructions
WARNING: Before attempting installation, read the 3300 ICP Safety Instructions available on the Mitel
Customer Documentation web site.
WARNING: Failure to follow all instructions may result in improper equipment operation and/or risk of elec-
trical shock.
3300 ICP Overview
The Mitel 3300 ICP is a converged Voice over IP (VoIP) solution that manages calls from IP devices
connected to an IP network and from TDM (time division multiplexing) devices on existing telephony
New Controller: MXe III-L The MXe III-L (L = LAN) 3300 ICP
controller is introduced to replace
the MXe III because controller
parts for the latter are no longer
available.
The MXe III-L controller requires
MiVoice Business Release 9.1 or
later.The MXe III-L controller uses
the same RTC/E2T compute
cards and MMC cards that the
MXe III controller supports with
MiVoice Business 9.1; the
performance of the MXe III-L
controller is the same as the MXe
III controller.
The MXe III-L controller is different
from the MXe III controller in the
following ways:
•No WAN support
•No LAN Port 2 support
•No L2 redundancy
•No IGMP filtering
•No 1G Ethernet speed for LAN
port
Global
The MXe III-L controller supports
MiVoice Business 9.1 or later only.
If you have to replace your MXe III
controller with an MXe III-L
controller, follow the instructions in
KMS article S05142.

NEW HARDWARE
CHAPTER 1 INTRODUCTION
networks. The 3300 ICP controller provides IP and TDM call processing. The 3300 ICP system may also
include Analog Services Units and peripheral cabinets to provide connectivity for analog and digital trunks
and telephones.
New Hardware
Mitel MiVoice Business Release 9.1
The AX controller now requires a single 16 GB Compact Flash (CF) for the system software, database,
and embedded voice mail, instead of the 2 GB/4 GB CF combo in pre-9.0 release. See Standard Config-
uration for AX.
MXe III-L Controller
The MXe III-L (L = LAN) controller was developed because some hardware parts of the MXe III controller
will no longer be available.
The MXe III-L controller supports MiVoice Business 9.1 and later only. The MXe III-L controller will be
available in Q1, 2020 only for the following regions: North America, UK, Middle East, Africa, Australia, and
New Zealand.
The MXe III-L controller uses the same RTC/E2T compute cards and MMC cards that the MXe III supports
with MiVoice Business 9.1; the performance of the MXe III-L controller is the same as the MXe III
controller.
The MXe III-L controller is different from the MXe III controller in the following ways:
•No WAN support
•No LAN Port 2 support
•No L2 redundancy
•No IGMP filtering
•No 1G Ethernet speed for LAN port
If you have to replace your MXe III controller with an MXe III-L controller, follow the instructions in KMS
article S05142.

DESCRIPTION
CHAPTER 2 3300 ICP CONTROLLERS
3300 ICP Controllers
Description
The 3300 ICP Controller contains the logic, processor, memory, communication interfaces, and call
control software for managing call processing on the system.
NOTE: Refer to the 3300 ICP Release 7.0 version of the Hardware Technical Reference Manual for details
on the older controllers; 100-user, 250/700-user, LX and MX.
Controller Types
•AX Controller
•MXe Controller
•CX II and CXi II Controllers
The Controller consists of the following main components:
• Real Time Complex (RTC): stores Call Control software and provides main control
• Ethernet to TDM (E2T): converts Time Division Multiplex voice streams to IP packets.
• Mid-plane: a circuit board that holds functional circuit blocks such as Ethernet devices and LEDs
• Echo Canceller: provides echo cancellation on IP calls.
• Quad Digital Signal Processor (DSP): provides telecom functions and G.279 compression
• Hard Disk (CXi II/MXe) : stores database, configuration data, and embedded voicemail.
•Compact Flash (AX) : stores database, configuration data.
•System i-Button: contains a unique serial number that identifies the controller for licensing purposes.
•Firewall (CXi/MXe excluding MXe III-L): secures the WAN port against unauthorized access by drop-
ping or rejecting unknown packets, allowing or disallowing IPSec and PPTP pass-through, and
performing many-to-1NAT (IP masquerading)
The WAN port and firewall in the CXi and MXe (excluding MXe III-L) is intended to be used either as
an access point for performing remote diagnostics and maintenance (similar to a MODEM) or, if the
Firewall function is disabled, as internal router to transparently route packets between the WAN port
and the controller's LAN ports.
NOTE: The WAN port and internal firewall should only be used as a network router in situations
where the amount of internet access is very low. For most installations, the Administrator should
employ a dedicated internet router/firewall.
• Stratum 3 Clock: provides synchronization for digital connections to external networks.
• Power supply: supplies power to the controller
Optional Components
The following modules can be installed to increase capacity, expand functionality or improve reliability
(see Field Upgradable and Replaceable Controller Modules):
•Quad Digital Signal Processor (DSP) Mitel Mezzanine Card (MMC)

The AX controller is ideal where a high density of analog devices is required. There are two typical system
configurations, standalone and networked, although as with any system, these functions may be mixed.
•The AX supports up to 48 T1 or 60 E1 on-board digital trunks, up to 112 IP phones, and 288 analog
phones (maximum 400 devices).
•The AX controller will support a second AC Power Supply Unit.

CX II and CXi II Controllers
The CX(i) II controllers are next-generation versions of the original CX and CXi controllers. Featuring
increased processing power, the CXi II can support up to 150 users and with fewer limitations on resource
(DSP) intensive applications. In fact, the base configuration of the CXi II has all the DSP resources the
system requires. You only need to add more DSP resources for enhanced functionality—for example,
T.38 fax support—not performance scaling. For more information on resource-related improvements to
the CXi II, see the “Engineering Guideline Updates” on page 14. Other key enhancements of and CXi II
include:
•choice of an 8 GB solid state (Flash) drive or a 80 GB spinning drive for mass storage media.
•two 21363 DSPs on the main board providing sufficient resources to support main telephony functions
(tone generation, tone detection, voice mail, record a call, 30-party conference) and 32 channels of
Echo cancellation.
•support for the new Application Processor Card (APC) which offers additional deployment options for
MiCollab solutions.
•redundant fans
The CX(i) II controller front panel consists of the following components:
•Three slots for expansion modules
•DB-9 RS-232 Maintenance Console Port used to access the operating system shell. Also supports
hardware flow control for an external modem. All other directed I/O function such as the virtual printer
port and embedded CPU serial port are accessed through either secure telnet or a TCP/IP socket.
•Dual USB 2.0 ports (for future use)
•CXi II only; 10/100 BaseT WAN port (RJ-45 connector) with built-in firewall
The WAN port and firewall is intended to be used either as an access point for performing remote di-
agnostics and maintenance (similar to a MODEM) or, if the Firewall function is disabled, as internal
router to transparently route packets between the WAN port and the controller's LAN ports.
NOTE: The WAN port and internal firewall should only be used as a network router in situations
where the amount of internet access is very low. For most installations, the Administrator should
employ a dedicated internet router/firewall.
•CXi II only; 10/100/1000 BaseT LAN port (RJ-45 connector)
•CXi II only; 16 10/100 BaseT 802.3af LAN ports connected to an internal Ethernet Layer 2 switch.
•Reset button
NOTE: The Reset button, resets the Ethernet/POE module and the main processor.
•Status LEDs - Power, media access, and alarm

CX II AND CXI II CONTROLLERS
CHAPTER 2 3300 ICP CONTROLLERS
10/100 802.3af LAN Ports (CXi II)
The CXi II includes a 16-port managed Layer 2 Ethernet switch. Each port supports auto-negotiation and
is able to connect to 10Base-T or 100Base-TX devices and determine the appropriate data rate from infor-
mation provided to it. Duplex mode and flow control are also programmable for each port. The ports use
8-way RJ-45 connectors that conform to Category 5 wiring standards. Although CAT5 cabling is recom-
mended, Category 3 can be used for limited installations. Refer to Appendix A and the Engineering Guide-
lines for CAT3 Cabling details.
The 16 ports comply with the 802.3af Power over Ethernet specification, which enables them to deliver
power to IP phones and other Ethernet devices over Category 3 or 5 cabling. As a minimum, the PoE
module provides enough power for 16 IP phones, some of which may be fitted with PKMs. For details
about PoE and planning a PoE installation, see the Engineering Guidelines on the Mitel Edocs web site
(http://edocs.mitel.com).
The internal switch uses 802.1p/Q VLAN prioritization to ensure the quality of voice calls, forwarding
packets with priority value 6 (from IP phones) ahead of packets with priority value 0 (from PCs and other
IP devices). Programming is required only if an expansion switch is connected. Refer to the CXi II Specific
Guidelines in the Engineering Guidelines document.

CX II AND CXI II CONTROLLERS
CHAPTER 2 3300 ICP CONTROLLERS
Standard Configuration for CXi II
•One 400 MHz MPC8360E processor
•1 GB of RAM
•Analog Main Board (AMB) for analog trunks and lines
•Embedded L2-PoE Ethernet switch with 16 ports (CXi II only)
•Stratum 3 clock
•Two 21363 DSPs on main board
Mass storage (spinning hard disk drive or solid state drive) is provided in a separately orderable kit. The
kit includes factory-installed Mitel MiVoice Business software.
The standard configuration does not support compression. Compression channels can be added using
the DSP-II card. The DSP II module provides up to 64 G.729 voice compression channels. This module
is also required for T.38 FAX. The DSP II module DOES NOT PROVIDE additional telephone resources
(tone detectors and receivers, voice mail, or conference).
Optional Configuration
You can add
•DSP II module for G.729 voice compression and FAX Relay (T.38)
•One or two T1/E1 Combo cards for digital trunking
•One or two Quad BRI Framer modules
•Analog Option Board (AOB)
•Quad CIM.
Dual or Quad DSP modules are supported but not required as the embedded 21363 DSPs provide suffi-
cient telephony resources .
