Chapter 1 Getting To Know Your ZyXEL Device
4-Port Switch
A combination of switch and router makes your ZyXEL Device a cost-effective and viable
network solution. You can connect up to four computers to the ZyXEL Device without the
cost of a hub. Use a hub to add more than four computers to your LAN.

Auto-negotiating 10/100 Mbps Ethernet LAN
The LAN interface automatically detects if they are on a 10 or a 100 Mbps Ethernet.
Auto-crossover 10/100 Mbps Ethernet LAN
The LAN interface automatically adjusts to either a crossover or straight-through Ethernet
cable.
cable.
Call Scheduling
Configure call time periods to restrict and allow access for users on remote nodes.
Network Address Translation (NAT)
NAT (Network Address Translation - NAT, RFC 1631) allows the translation of multiple IP
addresses used within one network to different IP addresses known within another network.
addresses used within one network to different IP addresses known within another network.
SNMP (Simple Network Management Protocol - Versions 1 and 2)
SNMP, a member of the TCP/IP protocol suite, allows you to exchange management
information between network devices. Your ZyXEL Device supports SNMP agent
functionality that allows a manager station to manage and monitor the ZyXEL Device through
the network.

IP Alias
IP Alias allows you to partition a physical network into logical networks over the same
Ethernet interface. The ZyXEL Device supports three logical LAN interfaces via its single
physical Ethernet interface with the ZyXEL Device itself as the gateway for each LAN
network.

ISDN Data Link Connections
The ZyXEL Device supports two types of ISDN Data Link Connections: point-to-point and
point-to-multipoint.

ISDN Basic Rate Interface (BRI) Support
The ZyXEL Device supports a single BRI. A BRI offers two 64 Kbps channels, which can be
used independently for two destinations or be bundled to speed up data transfer.
