7.5.4.3.12 Configuration | MEO
The optional IP Packet Processor must be installed and active, with IP-ACM or
V2-ACM selected as the active operating mode, and Carrier-in-Carrier disabled for
any MEO Operational Modes to be accessible. Otherwise, this page is
nonfunctional.
CDM-425 Advanced Satellite Modems are configurable for continuous pairing as Primary and
non-Primary Modems in an Antenna Handover System when the MEO feature is enabled.
Ethernet data traffic is transmitted and received via the Primary and Non-Primary CDM-625’s four
10/100 Ethernet ports. The Antenna Handover signal received from the user-provided IF/RF
switch determines which modem is the ONLINE or OFFLINE unit:
•
The ONLINE unit transmits traffic only to the WAN side while, at the same time, the
OFFLINE unit’s Tx is muted.
•
Both the ONLINE and OFFLINE units receive the satellite traffic, but only the ONLINE
unit forwards traffic to the LAN side while the OFFLINE unit drops the packets.
•
Any time a unit switches from the OFFLINE to ONLINE state, the traffic destined for the
WAN is buffered, preconfigured in milliseconds (base modem

delay).
