2. Operation Process
There are two-way of MM-5500PRO operation. One is PPP (Point to Point Protocol) mode
and the other one is PPPoE(PPP over Ethernet) mode.
and the other one is PPPoE(PPP over Ethernet) mode.
2.1 PPP mode
On PPP mode MM-5500PRO has the IP from ISP (Internet Service Provider) itself, so MM-
5500PRO can share the IP with many Host PCs. Below figure 3 shows PPP mode operation.

[Figure 3. PPP mode operation]
First, Host PCs get each private IP(hereby IP-1) from MM-5500PRO via DHCP server.
Second MM-5500PRO gets public/Private IP(hereby IP-2) from ISP via CDMA 1x EVDO
modem. Now MM-5500PRO has two kinds of IP, one is from ISP and the other ones are to
Host PCs. Third, MM-5500PRO convert network data between IP-1 and IP-2 via NAT.

2.2 PPPoE mode
On PPPoE mode MM-5500PRO has no IP, just the Host PC gets IP from ISP.
[Figure 4. PPPoE mode operation]
Different on PPP mode, the IP from ISP goes to Host PC directly. MM-5500PRO
converts protocol from PPP to PPPoE or on reverse direction, the Host PC processes all
network protocols.
