CDM-570/570L Satellite Modem with Optional IP Module
Typical IP Module Operation Setups
16.3.1 easyConnect™ Working Mode
This is the default Working Mode of the IP Module. easyConnect™ only operates in
Point-to-Point Mode, meaning that it is only communicating with one other
Comtech EF Data IP modem. This mode allows the modem to be setup with minimal
configuration (no specific routes need to be configured). In this mode, the IP Module is
acting as a "smart wire" over a satellite link between two Comtech EF Data IP modems.
This allows the IP Module to simultaneously forward IP traffic and non-IP traffic, such
as IPX.

This diagram shows a 256 kbps Point-to-Point duplex link in easyConnect™ Mode. Note
that both sides of the link are on the same IP subnet - 10.10.0.0/16. There are no routes or
HDLC addresses to configure. When the system is powered-up, all packets from each
subnet (local and remote) will be sent over the satellite interface. Each Comtech EF Data
IP Modem learns which devices are attached to their local Ethernet interfaces and will
only send packets over the satellite that are not destined for the locally attached devices.
The default setting in easyConnect™ Mode is 10BaseT/Half Duplex. Only 10BaseT
operation is allowed in easyConnect™, but Half or Full Duplex can be selected. In
Router Mode, the default setting allows the Ethernet port to auto-negotiate its link
