Definition
Adaptive Coding and Modulation / Variable Coding and
Modulation
This Advanced VSAT Network Working Mode configures the Traffic
ports of the CTOG-250 and CDM-840 to function as a Bridge.
Bridge Point-to-Multipoint Mode
CEFD Proprietary protocol that automatically synchronizes the
CTOG-250's Route table with the CDM-840's LAN connected
routes – i.e., the routes that are directed to the LAN ports of the
CDM-840.
Comtech Traffic Optimization Gateway 250.
Shared Aloha channel used in Vipersat dSCPC Mode that allows a
remote terminal to gain access to the Network.
A network in which all devices are directly connected to each
other and all devices are on the same IP subnet.
Internet Group Management Protocol
This Advanced VSAT Network Working Mode configures the Traffic
ports of the CTOG-250, CDD-880, and CDM-840 to function as a
Router.
This CEFD technology allows for dynamic creation of Single Hop
Mesh connections from one CDM-840 to another CDM-840. SHOD
requires the Vipersat Management System (VMS).
This mode, only available in the CDM-840, forces the Traffic
Interface to carry traffic for only one user-configured VLAN.
This is the default mode for BPM, where all packets (with and
without VLAN tags) arriving at the CTOG-250 and CDM-840 pass
through the system without modification. A trunked port can pass
two or more VLANs on the interface.
