THE AMIS- -49587
IEC 61334- -5- -1. The MAC layer is implemented by the
AMIS- -49587, the LLC layer should be implemented by the
external processor (See Figure 29).
on the power line (Physical Layer Frame) is composed of a
MAC Layer Frame, taken care of by the AMIS- -49587,
encapsulating a LLC Layer Frame that should be provided
by the external processors LLC layer.
*An unsolicited message is a message that is originating from the AMIS--49587, based upon an AMIS--49587 internal event. The message is

length of a MAC layer frame is only 38 bytes. The
maximum number of bytes that the AMIS- -49587 accepts in
one transmit command is 242 bytes. The AMIS- -49587
takes care of splitting these 242 bytes in smaller chunks,
encapsulate them in correct frames and send them over the
power line.
fields are omitted when the MAC frame is sent to the
external processor since they don’t contain useful
information to the LLC layer.
