The Mitel SX-200 CX / CXi Controllers have the processing, memory, mass storage, power, and input/output capabilities to support up to 100 IP phones or 100 ONS phones, or a combined total of 150 phones. While both controllers provide a cost-effective solution, the CXi offers the additional benefit of a 16-port Power over Ethernet Layer 2 switch and a 10/100 Base T WAN port. This permits small businesses without an existing switch to effortlessly create an office network with an “all in-one-box” solution.

CX Controller

CXi Controller
The SX-200 ICP CX and CXi controllers have the processing, memory, mass storage, power, and input/output capabilities to support up to 64 IP users. In addition to standard telephony interfaces, the CX includes a complete range of network interfaces. It has a WAN port for connection to the Internet and a Layer 2 switch for connection to the LAN. Each of the switch's 16 ports provides power to IP devices in compliance with IEEE 802.3af. The CX also has an unpowered 1 Gigabit port for connection to another switch on the LAN. For security, the CX can function as a firewall, dropping or rejecting unknown packets, allowing or disallowing IPSec and PPTP pass-through, and performing many-to-1 NAT (IP masquerading). The CX can also function as a PPTP server, enabling a remote client to access the CX on the LAN.

Analog Main Board (AMB) provides six LS (RJ11), four ONS (RJ11), with two PFT ports, a MOH (3mm) port, a Paging (RJ45) port, and a relay port that supports two generic relays.
Analog Option Board (AOB) provides an additional six LS (RJ11), four ONS (RJ11), with two PFT ports. The LS Trunk and ONS ports on the AOB have the same interface characteristics as the ports on the AMB. The PFT function is associated with ONS1/LS1 and ONS2/LS2 pair. The AOB also includes one Pager and a relay port that supports two generic relays for auxiliary bell, door sensor, or alarm.
One AC plug site is provided for the 85-265VAC universal power supply
