CDM-840 Remote Router MN-CDM840
Appendix H Revision 3
H–9
The CDM-840 supports header compression for Ethernet, and Layer 3, 4, and 5 headers.
The CDM-840 currently supports Router Mode operation only, so Layer 2 headers are
not transmitted over the satellite link. Therefore, there is no need for Layer 2 header
compression.
