Config: Misc  Stats (Statistics); Config: Misc  Meo (Medium Earth Orbit) - Comtech EF Data CDM-425 Installation And Operation Manual

6.2.1.10.4 CONFIG: Misc  Stats (Statistics)
Link Statistics Logging Interval:
The Logging Interval is the period over which performance statistics are to be measured. Use the
▲▼ arrow keys either to set this interval as 00 to disable the feature (i.e., no logging), or to select
a logging interval, in 10-minute increments, from 10 through 90 minutes. Press ENTER.
Access the 'SELECT: Monitor  Statistics' menu (Sect. 6.2.3.4) to view compiled Statistic logs.
6.2.1.10.5 CONFIG: Misc  MEO (Medium Earth Orbit)
MEO: Enable/Disable
(MEO requires ACM, PaP, and no Cnc)
MEO is non-functional when CnC is enabled.
CDM-425 Advanced Satellite Modems are configurable for continuous pairing as Primary and
non-Primary Modems in an Antenna Handover System when the MEO (Medium Earth Orbit)
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 → Antenna Handover
delay).
Press ENTER to open the Enable/Disable menu.
CONFIG: Misc  MEO  Enable/Disable
MEO Features: Enabled (Enabled,Disabled)
On the top line, the ▲▼ arrow keys to select the MEO feature as Enabled or Disabled. Press
ENTER. Once the MEO feature is enabled, you may now use the ◄ ►arrow keys to navigate to
the bottom line. Select Antenna Handover, and then press ENTER to continue.
