COMMON CONTROL CARDS
Common control cards are the core of system operation and are always
required in the IX-CME Gateway Controller. These cards include the
Central Processing Unit, Expansion Memory and Highway Expansion Cards
(Highway Expansion Cards are only required for Iwatsu Enterprise-CS to
ADIX expansion).
IX-CCU Central Control Unit
The IX-CCU Central Control Unit contains a 64-bit processor that controls
all Iwatsu Enterprise-CS functions. At a maximum capacity, this processor
will support up to 1024 TDM+IP devices. On board features of the IX-CCU
include a 1024-address DHCP server, and SIP call control servers, two
RS232C serial ports for system event output and administration access, 32
conference circuits that will each support a 4-party conference, an external
alarm indicator connector, and an external Background Music / Music On
Hold source connector, an FTP server and client for system software
upgrades, and an internal web server for SNMP (Simple Network
Management Protocol) access. The IX-CCU has connectors for the IX-
CCSU which is a required component for all ECS applications.
IX-CCSU Central Control Sub Unit
The IX-CCSU is a required component in all Iwatsu Enterprise-CS
applications. This card mounts on the IX-CCU and contains 128MB
compact flash memory which stores the master and backup database files.
This card also has two 10/100 Ethernet connectors one of which is
connected to the IX-MBU and provides the TCP/IP signaling data for the IP
devices. The other Ethernet connector is used for system programming
access. All licensing information for the ECS system is stored on the IX-
CCSU card.
IX-MBU Media Bridge Unit
The IX-MBU card provides media gateway services to/from any IP device
to/from any TDM station, trunk, or miscellaneous port. The IX-MBU,
installed in one of five 96-channel slots on the IX-CME, provides 24
channels for IP/TDM conversion in a base configuration. With the addition
of one or more IX-EMBU 24-channel DSP daughter cards, the IX-MBU
card may be expanded to provide up to 96 channels for IP/TDM conversion.
A maximum of 192 MBU channels are supported in the system. This will be
expanded to 480 MBU channels in a future release. The IX-MBU card
supports the IEEE 802.1p voice prioritization, TOS and DiffServ QoS
standards.
