DESCRIPTION
The MTC20136 is a dedicated controller chip, spe-
cifically designed to control operations of the ST-
Microelectronics DynaMiTe chipset. The
MTC20136 offers direct glueless interfaces to the
MTC20135 and MTC20455 DMT/ATM transciever
and implements a complete control interface for
parameters and commands exchange between
transceiver and system management. All real time
ADSL-related functions (including EOC process-
ing) are completely handled by the MTC20136.
