Non-Vipersat Multipoint Modes
Item Description
Multipoint Hub Router
When in static SCPC (non-Vipersat mode), the option exists for configuring the
modems into a hub and spoke network with a shared outbound at the hub. All of the
modems at the hub should be put in “Multipoint Hub Router” mode.
Note: If a modem at the remote is configured to be a Hub router there will be
significant degradation to network performance due to the potential for routing loops.
Multipoint Remote Router
Select Multipoint Remote Router for all remote modems in a non-Vipersat multipoint
network. A Remote router would be classified as a modem which receives the shared
outbound and transmits back to the hub on a dedicated SCPC channel
Non-Vipersat Point-to-Point Mode
Item Description
Point-to-Point Router
Select for use in a Point-to-Point SCPC link where there are different IP subnets on
either side of the link.
Routing Mode
Item Description
Gigabit Ethernet Bridge
Select for use in a Point-to-Point SCPC link when you wish to bridge traffic (no IP
network routing).
Note: This mode is currently only compatible with the Gigabit Ethernet bridge card for the
SLM-5650A. Ethernet communication between the Base Modem and the NP Interface
is disabled, as the Base Modem does not support secure network management
interfaces
Router
When the modem is operating in Router Mode, a number of Base Modem M&C
parameters are available via the NP HTTP Interface. Similarly, a limited number of
status-only NP parameters are viewable over the Base Modem HTTP Interface.
BPM
When BPM Mode is selected, the NP Interface Ethernet ports P1 through P4
transparently bridge data traffic, and network management is only possible using the
Base Modem’s J5 Ethernet port.
Note: In BPM Mode, the Gigabit Ethernet Bridge option becomes inaccessible and the
appearance of the Routing Mode section changes as follows:
