Network Address Translation (NAT):
 Single networks can connect to 
the Internet with this function.  The  Express 4110/4120 translates out-
going IP packets over the ISDN to the IP router at the Internet  Service 
Provider. Popular Internet applications are supported.

POTS: 
The POTS interfaces can be used for interfacing to dual tone 
multi-frequency (DTMF) analog devices such as telephones, modems, 
fax machines, etc. 
Demand Routing and Bridging with the Express 4110/4120
The Express 4110/4120 is a dial-up ISDN IP Router and Transparent 
Learning Bridge that provides Dial-On-Demand and Dynamic Bandwidth 
Management.  Its features can be easily configured and used once several 
basic concepts are understood.  
Factory Default
The Express 4110/4120 comes from the factory configured for MAC 
Bridging, IP routing, and IPX routing with no filters or connection infor-
mation defined. An IP address of 10.0.0.1 with a network mask of 
255.255.255.0 is preloaded. Dynamic Bandwidth Management features are 
disabled.  Although dynamic assignment of a B-channel for the analog 
(POTS) ports on the Express 4110/4120 is always available, link idle time-
out and adding/removing of B-channels based on traffic is initially dis-
abled.
