Sub-Mux capability can be used with the IP Packet Processor to multiplex a primary serial
synchronous or G.703 traffic stream with IP.
18.2.4 Adaptive Coding and Modulation (ACM)
Chapter 17. ADAPTIVE CODING AND MODULATION (ACM)
Comtech EF Data’s VersaFEC® Adaptive Coding and Modulation (ACM) feature, a patents-
pending technology wholly owned and developed by Comtech EF Data and CEFD sister division
Comtech AHA Corp., can be used with the IP Packet Processor to maximize throughput.
ACM converts available link margin into additional throughput, thereby maximizing throughput
under all conditions, including rain fade, inclined orbit satellite operation, antenna mispointing,
interference and other impairments.
