36
288 analog sets and 288 IP sets, for a combined total of 576 devices. Up to 300 IP devices
can be supported under low traffic conditions.
• MXe III Standard Controller: supports a maximum of 300 IP devices or 350 ONS devices
(or a combined maximum of 350 IP/ONS devices)
• MXe III Expanded Controller: supports a maximum 1400 IP devices or 1500 ONS (or a
combined maximum of 1500 IP/ONS devices)
Controllers can be networked together over an IP infrastructure to deliver solutions for large or
multi-site organizations.
Modules are field replaceable units (FRUs) that expand the functionality and capacity of the
controller. Modules are installed in external and internal slots in the controller. The number of
available slots depends on the controller model. Communication interface modules, such as
Dual FIM, Dual T1/E1, T1/E1 Combo Card, and Quad BRI modules, are installed in slots that
are accessible externally from the front or rear panel of the controllers.
The controllers have the following common physical features:
• External casing: all of the components may be stacked or rack-mounted (in a 19-inch rack).
• Power supply: each unit has its own standard male IEC AC input connector for power.
• LEDs: the LEDs are located on the front or rear of the units for indication of circuit status.
• LAN/WAN ports: RJ-45 connectors
• Maintenance port: DB-9 (RS-232)
The following sections provide an overview of the controller variants. For detailed information
on controller capacities, refer to the controller configuration tables in the 3300 Integrated
Communications Platform Engineering Guidelines.
CX II and CXi II Controllers
The CX II/CXi II comes with an embedded Analog Main Board that supports 6 analog trunks
and 4 analog extension ports. The CX II/CXi II includes the required DSPs in the base
configuration. You need to add cards and DSP resources only for additional functionality, not
for performance scaling.
The CX II and CXi II Controllers support
• Up to 150 IP devices, or up to 150 combined IP/ONS devices
• The Analog Main Board (AMB): provides six LS trunk ports with CLASS support (CLASS
is available in North America and Latin American only), four ONS ports, a single Mu-
sic-on-Hold port (one source supported), a single Paging port (one paging zone), and two
System Fail Transfer circuits.
• The Analog Option Board (AOB): provides six LS trunks ports with CLASS support, four
ONS ports, one System Fail Transfer circuits and one paging circuit
• One 10/100 BaseT WAN port (RJ-45 connector)
• One 10/100 BaseT LAN port (RJ-45 connector)
