D.1 Sample Applications
The following section provides brief application notes for operating the modem and explains by
example how to configure the modem for some of the most popular configurations.
The following information illustrates the allowable combinations for Mode and Data Rate.
Allowable Combinations: Mode/Rate/Framing.
IBS:
2.048 Mbps or below 1/2, 3/4, 7/8 Rate
Closed Network:
8.448: No Framing, 3/4, 7/8 Rate FEC
6.312: No Framing, 1/2, 3/4, 7/8 Rate FEC
2.048: 1/15 Framing or No Framing, 1/2, 3/4, 7/8 Rate FEC
1.544: 1/15 Framing or No Framing, 1/2, 3/4, 7/8 Rate FEC
Any Rate 2.048 & lower: 1/15 Framing or No Framing, 1/2, 3/4, 7/8 Rate FEC
