AM200 Modem 22
6.3 ETHERNET
6.3.1 CONFIGURATION AS A BRIDGE
The User's PC and the Network are connected directly together and so must be on the same IP subnet.
Figure 12 AM200 to PC Connection
Figure 12 shows a PC connected to a local LAN. If the user wishes to connect a remote PC to the LAN then
a pair of AM200s may be used to bridge between them as shown in Figure 13.
Figure 13 AM200 Bridge
Bridging is the default mode of operation of the AM200.
Connect the AM200 over the transmission line to form the wide area link. Connect the LAN to the 'CO'
AM200 with a straight cable. Connect the PC to the 'CPE' AM200 with a crossover cable.
AM200s are supplied with a default address and subnet mask as follows.
IP address 10.254.254.253
Subnet Mask 255.0.0.0
The IP address of one of the AM200s will have to be changed so that the two don't clash. If the address
clashes with something else on the network then both will have to be changed.
