Functional Description

Figure 1-2. Advanced VSAT Series Network Topology Example
Figure 1-2 illustrates the CDM-840 Remote Router as deployed in a typical satellite-based
communications network – in this example, a hub-and-spoke IP Network.
The CDM-840 utilizes a high performance processor and a real-time operating system (RTOS)
combined with multiple Field Programmable Gate Arrays (FPGAs) for optimal performance. All
non-volatile memory is provided onboard. Field upgrades are easily uploaded via satellite or the
Ethernet port; software-based options are added to the unit via FAST (Fully Accessible System
Topology) upgrade.
The CDM-840 runs on an embedded operating system and does not have moving parts for media
storage. This design provides carrier class reliability and high speed, purpose-driven processing.
The unit can be managed through multiple interfaces providing options for both in-band and out-
of-band monitor and control:
•
SNMP MIB II and Private MIB
•
HTTP Web-based Management
•
EIA-232 serial remote control
