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.
: Refer to the 3300 ICP Release 7.0 version of the Hardware Technical Reference Manual for details
NOTE
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.
: The WAN port and internal firewall should only be used as a network router in situations
NOTE
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)
