5.3.2.2 Modem-to-User IP (10/100 Ethernet) Interface Examples
5.3.2.2.1 Data Interface Connections using IP Sub-Mux
• Chapter 15. IP SUB-MUX in CDM-625 Advanced Satellite Modem Installation
and Operation Manual (CEFD P/N MN-CDM625)
• Appendix N. IP SUB-MUX in CDM-625A Advanced Satellite Modem Installation
and Operation Manual (CEFD P/N MN-CDM625A)
Subsystem Multiplex – referred to by CEFD as Sub-Mux – is a secondary framing structure that
combines one to four ports of IP (10/100 Ethernet) traffic (see Figure 5-11) with any currently
available combination of framing and interface type (see Figure 5-3 through Figure 5-10) –
excluding IP itself. The composite data rate to the modulator and from the demodulator is
referenced to the primary, non-IP data interface rate by a specific user-selected ratio.
5.3.2.2.2 Managed Switch Mode (with/without IP Packet Processor)
Figure 5-11 shows the block diagram for the CDM-625/A diversity switching configuration using
the IP (10/100 Ethernet) Interface in Managed Switch (Ethernet Bridge) Mode. Figure 5-12
shows the cabling example for this setup.
This configuration requires no cabling kit – you must use user-provided Ethernet cables and
Layer 2 switches for direct connection to the modem via one to four RJ-45 ports. This cabling
example shows use of all four Ethernet ports.
