CDM-570/570L Satellite Modem with Optional IP Module 
Revision 4 
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.

Figure 16-1.  easyConnect
 Diagram 
 
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. 
 
IMPORTANT
 
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 
speed on power-up.
