Preliminary Information
them to the local streams, the MT90866 satisfies
these higher bandwidth applications.
Depending on the application, the CPE or access
equipment may need to terminate internet traffic and
switch the traffic to the appropriate destination. Most
of these applications employ banks of DSP’s to
handle the modem calls. When the local streams are
used to route traffic to these DSP cards, the
MT90866
application requires a high local switching capability
on each card. This requirement is easily handled by
the MT90866, with its local switching capacity of 2,
432 channels.
