Distribution Line Carrier (DLC) communication. It serves
two major and two minor types of applications:

A Master is a client to the data served by one or
many slaves on the power line. It collects data from
and controls the slave devices. A typical application
is a concentrator system
♦
Slave or Server:
A Slave is a server of the data to the Master. A
typical application is an electricity meter equipped
with a PLC modem.

data that comes across the power line. Only the
physical layer frame correctness is checked. When
the frame is correct, it is passed to the external
