Connecting to a LAN
through UB Access/One
You can use X25AM to connect a Tandem system to a local LAN through an
Ungermann Bass (UB) gateway (Figure 2-8). The LAN can consist of different types of
terminals and printers. The various terminals and printers can all communicate
through the UB Access/One interface to a Tandem system over a single X25AM line.
The subdevices in this type of configuration should be defined with the ITI protocol,
just as the remote or local subdevices that connected through a PAD.
