ECM Remote Configuration
• Mode: – Use the drop-down list to select operation as Disabled, Offline, Wait, or Online.
Each ECM state establishes a different role for the CDM-840 in the overall Advanced VSAT
Network operations:
o Online – This is the most common ECM state, whereby the CDM-840 powers up,
requests network registration, and switches to dSCPC at the minimum site policy data
rate setting.
o Wait – Allowing all CDM-840s in the network to automatically request dSCPC bandwidth
can result in oversubscription, where some percentage of CDM-840s wait their turn for
SCPC pooled resources. To avoid oversubscription, the ECM Wait State provides the
network operator with the ability to selectively control the CDM-840s through manual,
scheduled, or externally switched request commands.
With the CDM-840s set to Wait, they continue to send their health status update
messages to the VMS and to the CTOG-250 Comtech Traffic Optimization Gateway (with
integrated CDM-800 Gateway Router). The VMS messages update connected link status;
