CDM-600L Satellite Modem
EDMAC Channel
11.4
Drop & Insert ++
A new variation of EDMAC is available with D&I++ framing. With this, each frame
contains 2944 bits, with 64 overhead bits and 2880 user data bits. The portion of the
overhead used for the EDMAC link performs identically to that of the EDMAC frame,
but because D&I++ uses a smaller overhead, the two modes are not compatible with each
other.
