CDD-562L/564 Demodulator with IP Module Revision 2
CDD-56X CLI and Telnet Operation MN/CDD564L.IOM
8–10
Selection Entry Description
IGMP I Toggles [Enabled] or [Disabled]. If Enabled:
• The receive portion of a demodulator utilizes the demodulator
as an IGMP server.
• The transmit portion of a demodulator utilizes the
demodulator as an IGMP client.
• The IGMP Information page configures the demodulator to
report an interest to join a Multicast group on an IGMP server.
• The IGMP protocol regulates the Multicast traffic on a LAN
segment to prevent information of no interest from consuming
bandwidth on the LAN.
Downlink Route All Available
Multicast
M Toggles [Enabled] or [Disabled]:
• When Enabled, the demodulator routes all Multicast packets
coming from the Satellite interface to the Ethernet LAN
regardless of the Route Table entries.
• When Disabled, the demodulator does not automatically
forward all Multicast packets. This demodulator will only
forward multicast traffic received from the satellite to the
Ethernet port if the multicast route exists in the Route Table.
Receive 3XDES Decryption [RO] This option is always available if purchased.
• When Available, the demodulator decrypts packets being
received from the Satellite Interface.
• When Unavailable, the demodulator cannot decrypt packets
received from the Satellite Interface. This option is auto-
sensed by a bit carried in packet headers.
Rx Header Compression (Per
Demod)
K Toggles [Enabled] or [Disabled].
This option is set per Rx Channel. For each Rx Channel:
• Enabled – Perform Header Decompression.
• Disabled – Does not perform Header Decompression.
When Enabled, the system expects received streams to be Header
compressed.
Note: A CDM-IP modem (or demodulator) must receive all
streams as compressed or not compressed – the unit has no
way to distinguish between the two.
Rx Payload Compression [RO] This option is always available if purchased.
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.
FAST Feature Code V Allows the entry of a FAST Option Pruchase Access Code that has
been provided by the Comtech EF Data Sales Representative
upon purchase of a specific option/upgrade.
Vipersat Feature Codes F Allows user to enter a Vipersat features activation code that has
been provided by Comtech Vipersat for modems (or demodulators)
configured to operate under VMS control.
