CDM-570/570L Satellite Modem with Optional IP Module
Appendix G
The incorporation of Comtech Streamline Encapsulation results in operational changes from IP
Module V1 FW Ver. 1.6.# and earlier / IP Module V2 FW Ver. 2.1.# and earlier as follows:
•
HDLC addressing modes have been removed
•
HDLC addresses have been removed to reduce overhead and deployment configuration
complexity
•
Rx Header Compression is now automatically determined from the Streamline
Encapsulation information – this removes the need to configure the Rx Header
Decompression feature (these options have been removed)
With IP Module V1 FW Ver. 1.7.# and later / IP Module V2 FW Ver. 2.2.# and later, the Streamline
Encapsulation working modes' operation, which has been centralized in the single Working Mode
configuration parameter, is as follows:
•
Managed Switch – Functions a managed switch with support for VLAN as well as advanced
features such as QoS, Header Compression and Payload Compression. Primarily intended for
operation in a point-to-point topology.
•
Router-Hub – Functions as the Hub side router in a Point-to-MultiPoint network. Allows Sat-to-
sat packets to pass. No longer requires per-route HDLC addresses to be configured.
•
Router-Remote – Functions as a Remote Router in a Point-to-MultiPoint network. Packets from
the WAN are not allowed to be sent to the WAN. No longer requires HDLC receive addresses to
be configured.
•
Router-Point to Point – Functions a point to point router in point to point configurations.
•
Vipersat Router – Hub-Hub router in a Vipersat Network
•
Vipersat Router – Hub Expansion-Hub Expansion router in a Vipersat Network.
•
Vipersat Router – Remote-Remote router in a Vipersat Network
•
Vipersat Router – Remote Expansion-Remote Expansion Router in a Vipersat Network.
The Vipersat "Unit Role" and "Expansion Role" parameters are not read-only.
