Chapter 1 Getting To Know the ZyXEL Device
Multiple PVC (Permanent Virtual Circuits) Support
Your device supports up to 8 Permanent Virtual Circuits (PVC’s).
IP Alias
IP alias allows you to partition a physical network into logical networks over the same 
Ethernet interface. Your device supports three logical LAN interfaces via its single physical 
Ethernet interface with the your device itself as the gateway for each LAN network.
IP Policy Routing (IPPR)
Traditionally, routing is based on the destination address only and the router takes the shortest 
path to forward a packet.  IP Policy Routing (IPPR) provides a mechanism to override the 
default routing behavior and alter the packet forwarding based on the policy defined by the 
network administrator. 
Packet Filters
Your device’s packet filtering function allows added network security and management.
Ease of Installation
Your device is designed for quick, intuitive and easy installation. 
Housing
Your device's compact and ventilated housing minimizes space requirements, making it easy 
to position anywhere in your busy office. 
1.3  Wireless Features (“W” models only)
IEEE 802.11g Wireless LAN 
IEEE 802.11g is fully compatible with the IEEE 802.11b standard.  This means an IEEE 
802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa) 
at 11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps 
between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation 
are as follows:
