ZyXEL Communications Prestige 100, User Manual

Page: 14 / 130

2 Introduction
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. Please see Chapter 13 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.
Networking Protocol Support
The Prestige offers support for TCP/IP.
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
needed to allow for greater efficiency in data transfer. It supports
BAP (Bandwidth Allocation Protocol) and BACP (Bandwidth
Allocation Control Protocol) to manage the number of links in
multilink bundle.
