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 256 MB 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
34
of 192 MBU channels are supported in the system. The IX-MBU card
supports the IEEE 802.1p voice prioritization, TOS and DiffServ QoS
34
192 MBU channels supported with G.729 compression. Maximum of 160 MBU channels at
G.711 compression.
