ISDN Basic Rate Interface (BRI)
Using either a standard S/T or U Interface (128 uses the S/T
interface and 128U uses the U interface) the Prestige supports a
full range of switch types. The switch type depends on the CO
(Central Office) switch your ISDN line is connected to. See
Chapter 16 for more information on North American, European,
and Asian ISDN firmware and switch types supported by the
Prestige.
The two B-channels can be used independently for two
destinations. Or they can be bundled for one connection to support
bandwidth-on-demand.
Multiple Networking Protocol Support
The Prestige is a multi-protocol router. It supports TCP/IP, Novell
IPX, and Transparent Bridging.
Standard Phone Jack
The Prestige is equipped with two standard phone jacks to connect
to telephones, FAX machines, or modems. This allows the ISDN
line to be used for voice calls as well as data calls.
Dial On Demand
The Dial On Demand feature allows the Prestige to automatically
place a call to a Remote Node whenever there is traffic coming
from any workstation on the LAN to that remote site.
Bandwidth On Demand
The Prestige supports bandwidth up to 128Kbps over a single ISDN
BRI line. It incorporates PPP/MP (Point-to-Point
Protocol/Multilink Protocol) to bundle two B channels over a BRI
line. In addition, the Prestige dynamically allocates bandwidth
between the two B channels, increasing or decreasing speeds as
