MXe Controller
The MX Expandable Controller (MXe), introduced in Release 7.0, is scalable from 40 to 1400
users. The MXe Controller replaces the MX and LX controllers, allowing a smaller system to
be expanded to increase capacity rather than requiring a platform upgrade. The initial
configuration supports 200 active users.
• The MXe controller ships with one 450 MHz RTC processor, a 128 channel echo canceller
and DSP resources (equivalent to two Quad DSP modules), a hard drive, and an Analog
Main Board (AMB).
• The MXe controller can be upgraded with the addition of a second processor, E2T, to
increase capacity.
• Redundancy is available with the addition of a RAID controller and two hard disks, and a
second AC PSU.
• The MXe supports the same Analog Main Board (AMB) as the CX/CXi with six analog trunks
and four analog extensions. It does not support the Analog Option Module (AOB).

The Controller front panel consists of the following components:
• Four expansion modules
•Alarm port
• Two DB-9 ports, connected to the RTC, for maintenance and printer purposes
• Two 10/100/1G BaseT Ethernet LAN ports (RJ-45 connector)
• One 10/100 BaseT Ethernet WAN port (RJ-45 connector)
• Four CIM ports
• Remote alarms on/off
