when the prime is faulted, the backup will not take over. Also, the user will have the
option to do force switching.

Comtech EF Data proprietary framing is included. The framing permits the bi-directional

backwards compatible with the CDM-500, CDM-550, CDM-550T, CDM-600 and
CDM-600L. EDMAC-2 is a reduced overhead version of EDMAC, and is not backwards
compatible with the modems listed above.
