WAN Mode
The E7 allows for Ethernet bridge functionality in either a point-to-point (PtP) or a point-to-multipoint
(PtMP) satellite network. This functionality is configured in the menu item
<Intf: Send WAN Mode>
for the transmit modem section and
<Intf: Rcv WAN Mode>
for the receive modem section.
NOTE: The E7 allows for over the satellite interoperability with some legacy Datum modems by
setting the menu item
<Intf: Send WAN Protocol = M500 HDLC>
and
<Intf: Rcv WAN
Protocol = M500 HDLC>
. The default mode is
<Intf: Send WAN Protocol = M7 HDLC>
and
<Intf: Rcv WAN Protocol = M7 HDLC>
for operation in a network that has all M7
modems installed.
Configuration of the proper “WAN Mode” and “WAN Protocol” will automatically set the proper MAC
learning and packet forwarding to prevent duplicate MAC addresses and enable proper network
operation.

Point-to-Point (PtP) Satellite Network
Figure 3-45 shows a typical PtP satellite network that could be used for extending a local LAN and
Internet access to a single remote location.
Figure 3-45 - Point-to-Point Satellite Network
In the PtP example shown in Figure 3-45, the E7 configuration is very simple for the user. The menu
setting would be the same on the modems at both ends of the satellite link.
<Intf: Send WAN Mode = Bridge PTP>
<Intf: Rcv WAN Mode = Bridge PTP>
