ZyXEL Communications Prestige100 Networking Protocol Support, Standard Phone Jack, Dial On Demand

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.
