1. What is ZyNOS?

ZyNOS is ZyXEL's proprietary Network Operating System. It is the platform on all Prestige routers that

delivers network services and applications. It is designed in a modular fashion so it is easy for

developers to add new features. New ZyNOS software upgrades can be easily downloaded from our FTP

sites as they become available.

2. How do I access the Prestige SMT menu?

The SMT interface is a menu driven interface, which can be accessed via a RS232 console or a Telnet

connection. To access the Prestige via SMT console port, a computer equipped with communication

software such as HyperTerminal must be configured with the following parameters.

● VT100 terminal emulation

● 9600bps baud rate

● N81 data format (No Parity, 8 data bits, 1 stop bit)
