+DCE Internal implementation
+===========================
+
+This chapter provides a detailed description of the classes and building blocks of the esp-modem component and their responsibilities.
+
+The esp-modem actually implements the DCE class, which in turn aggregates these thee units:
+
+- :ref:`DTE<dte_impl>` to communicate with the device on a specific Terminal interface such as UART.
+- :ref:`Netif<netif_impl>` to provide the network connectivity
+- :ref:`Module<module_impl>` to define the specific command library

+DTE abstraction
+---------------
+
+DTE is a basic unit to talk to the module using a Terminal interface. It also implements and uses the CMUX to multiplex
+terminals. Besides the DTE documentation, this section also refers to the
+
+- :ref:`Terminal interface<term_impl>`
+- :ref:`CMUX implementation<cmux_impl>`
