CDM-625A Advanced Satellite Modem
Appendix L
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.
L.2.4 Subsystem Multiplex (Sub-Mux)
Appendix N. IP SUB-MUX
Sub-Mux is a secondary framing structure that combines IP traffic with any currently available
combination of framing and interface type (excluding IP itself). A specific, user-selected ratio
references the composite data rate to the modulator and from the demodulator to the primary,
non-IP interface rate.
Sub-Mux capability can be used with the IP Packet Processor to multiplex a primary serial
synchronous or G.703 traffic stream with IP.
