Getting to Know Your Bridge/Router
This chapter describes the key features and applications of your Prestige 153/153X WAN
Bridge/Router.
1.1 Prestige 153/153X WAN Bridge Routers
Congratulations on the purchase of your ZyXEL Prestige 153/153X Remote Access Router. Your
Prestige integrates the routing and bridging functions in a single package, and is ideal for
everything from Internet browsing to receiving calls from telecommuters to making LAN-to-LAN
connections to remote networks.
Both Prestige 153 and 153X are equipped with three WAN (Wide Area Network) ports that can be
connected to the PSTN (Public Switched Telephone Network) via modems or to the ISDN
(Integrated Service Digital Network) via TAs (Terminal Adapters).
In addition, the Prestige 153X supports synchronous mode on two of the WAN ports, allowing it
to connect to FT1/FE1 (Fractional T1/E1) leased lines via CSU/DSUs (Channel Service Unit/Data
Service Units).
1.2 Features of Prestige 153/153X
The following are the key features of the P153/P153X.
•
Multiple WAN Ports
Your Prestige 153 features three WAN ports (WAN-1, 2 and 3). Each WAN port can be connected
to a dial-up/leased line modem or to an ISDN TA (Terminal Adapter). The WAN ports can be
used independently, or they can be bundled to support PPP Multilink Protocol (PPP/MP ) to boost
bandwidth.
Two of the WAN ports on P153X also support synchronous mode operation for leased lines.
•
Leased Lines Backup
For leased lines, the Prestige provides backup support in the event of leased line failure with dial-
up lines.
