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>`

This is a namespace holding a library of typical AT commands used by supported devices.
Please refer to the :ref:`c_api` for the list of supported commands.
