Description
By integrating key functions needed in voice telecom
application, the Integrated Digital Switch (IDX)
provides a solution-on-a-chip for key telephone
systems, PBX applications or CTI designs. Figure 2
shows a typical configuration.
The
interchange capability for B, C and D channels, up to
a maximum of 192 channels. It offers conference call
capability for 15 parties over a maximum of 5
conference bridges. With its integrated PLL, the
MT90812 provides the necessary clocks to support
peripheral
devices,
such
interconnected IDX devices. Integrated into the IDX
is the capability to detect supervisory signalling and
to generate FSK 1200-baud signals. In addition, an
integrated
digital
tone
continuous dual tones, including standard DTMF.

With its programmable gain control, the IDX allows
users to use codecs without gain control and also
centrally manage conference calls.
To support both small and large switching platforms,
a built-in expansion Bus allows the interconnection of
up to 4 IDX devices or external components such as
digital
switches.
When
interconnected, the array is capable of switching 256
channels (64x4), handling 60 conference parties
(15x4) and generating additional tones including
programmable ones. Other functions are also
increased in this configuration. The functional block
diagram is shown in Figure 1.

An evaluation board, MEB90812, is available
complete with software and a user manual, which
demonstrates the layout of a typical application
board and facilitates the use of the MT90812, and
peripheral devices such as Mitel’s DNIC products.
