The following features are not supported when in BPM Mode:
• The standalone CDM-800* does not support BPM due to packet per second limitations.
• Single Hop on Demand (SHOD) Mesh.
• CDD-880 Port Diversity.
*Starting with Firmware Ver. 1.5.1.X, the CDM-800 no longer supports standalone
mode. The CDM-800 must be paired with a CTOG-250.
The Advanced VSAT BPM Working Mode has the following detailed specifications:
Attribute Value Comments
