receive all streams compressed or not compressed. The
modem has no way to distinguish between compressed
or not compressed.
C This option allows a stream of traffic to be payload
compressed. Payload is considered everything inside
the HDLC satellite frame. Therefore, IP headers could
be compressed as well. Note that in easyConnect™

Router mode, Payload compression will show Available,
and one must set the option Per Route in Routing table.
