Description 
Receive 3XDES Decryption 
Read 
Only 
This feature must be purchased. 
Available allows the 
IP M
odule to decrypt packets being 
received from the Satellite Interface.  
When Unavailable the 
IP M
odule cannot decrypt 
packets received from the Satellite Interface. This option 
is auto-sensed by a bit carried in packet headers. This 
option is always available if the option is purchased. 
Tx Header Compression 
This option will compress headers. Headers available 
for compression can be referenced in the IP Header 
Compression section. Note that in easyConnect
™ mode 
all Ethernet Headers will be compressed whether or not 
this feature is enabled. In Router mode, this screen will 
show Available, and the option must be enabled per 
route in Route table. 
Rx Header Compression 
This option tells the system to expect received streams 
to be Header compressed. Note a CDM-IP modem must 
receive all streams compressed or not compressed. The 
modem has no way to distinguish between compressed 
or not compressed. 
Tx Payload Compression 
This option allows a stream of traffic to be payload 
compressed. Payload is considered everything inside 
the HDLC satellite frame. Therefore, IP headers could 
be compressed as well. Note that in easyConnect
™ 
mode, the option is enabled/disabled for all traffic. In 
Router mode, Payload compression will show Available, 
and one must set the option Per Route in Routing table. 
Rx Payload Compression 
Read 
Only 
Receive payload compression option allows a unit 
receiving a stream of data that has been payload 
compressed to be correctly uncompressed. This option 
is auto-sensed by a bit carried in packet headers. This 
option is always available if the option is purchased. 
Vipersat Feature Codes 
This option allows a user to enter a Vipersat features 
enable code that has been provided by Comtech 
Vipersat for modem configured to operate under VMS 
control. 
Save Parameters 
This option allows a user to save the current 
configuration to permanent storage. This configuration 
will be restored on each successive power cycle. 
Exit 
This option allows a user to exit the current menu and
