An Introduction to Switch Integration
and DCIU
Switch integration refers to the sharing of information between a voice
messaging system and a switch to provide a seamless interface to callers and
subscribers. A fully integrated voice messaging system answers calls with
information taken directly from the switch.
To create an integrated environment for the Lucent I
NTUITY system and System 85
or DEFINITY® Communication System Generic 2 (G2) switch, the system uses a
Digital Communications Interface Unit (DCIU) link to the switch. The DCIU link
transfers digital call information, such as called and calling party information, to
the Lucent I
NTUITY system. The system exchanges analog voice information with
the switch through analog telephone lines.
DCIU acts as a processor with nine physical links. One of the links connects to
the switch processor. The remaining eight links can connect to external
processors, such as a Lucent I
NTUITY system, an AUDIX® system, another switch
on a Distributed Communications System (DCS), or a Call Management System
(CMS). Each of the DCIU physical links has 64 logical channels. The 64 channels
can be distributed to the external adjuncts using various methods.
When integrated through a DCIU link, the Lucent I
NTUITY system sends message
packets to the switch using the BX.25 protocol at 9.6 Kbps. The messages
received by the DCIU from the Lucent I
NTUITY system can be routed to something
else, such as the host switch, or they can be routed on another outgoing channel.
This processing power allows a remote switch on a DCS, a host switch, and a
Lucent I
NTUITY system to work together.
Switch Releases Supported by the
