Compression statistics – the total bytes of the pre-compressed and post-compressed traffic and
effective compression ratio. The CDM-840 supports header compression for Ethernet, and Layer
3, 4, and 5 headers.
The CDM-840 currently supports Routing Mode operation only, so Layer 2 headers
are not transmitted over the satellite link. Therefore, there is no need for Layer 2
header compression.
