2.

IP Router:  

The Express L128/L128T can function as an IP router using the 

Routing Information Protocol (RIP) for advertising and learning routes 
among other routers.  Static routes may also be entered into the routing ta-
ble.

3.

IPX Router:

 IPX routers and services can be exchanged between the Ex-

press L128/L128T and other devices using RIP and Service Advertising 
Protocol (SAP). Watch dog serialization filtering and spoofing can permit 
the ISDN to be idle during no application traffic periods.

4.

Network Address Translation (NAT):

 Single networks can connect to the 

Internet with this function.  The  Express L128/L128T translates outgoing 
IP packets over the ISDN to the IP router at the Internet  Service Provider. 
Popular Internet applications are supported.

5.

POTS: 

The POTS interfaces can be used for interfacing to dual tone multi-

frequency (DTMF) analog devices such as telephones, modems, fax ma-
chines, etc.  The Express L128T POTS option is available on part number 
1202070L2 only.

Demand Routing and Bridging with the Express L128/L128T

The Express L128/L128T is a dial-up ISDN IP Router and Transparent Learn-
ing Bridge that provides Dial-On-Demand and Dynamic Bandwidth Manage-
ment.  Its features can be easily configured and used once several basic 
concepts are understood.  

Factory Default

The Express L128/L128T comes from the factory configured for MAC Bridg-
ing, IP routing, and IPX routing with no filters or connection information de-
fined. 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.  Al-
though dynamic assignment of a B-channel for the analog (POTS) ports on the 
Express L128T model is always available, link idle time-out and adding/re-
moving of B-channels based on traffic is initially disabled.
