FEATURE DESCRIPTION
High Speed Internet
Access
The ZyXEL Device supports transmission speeds of up to 43
Mbps upstream and 30 Mbps downstream. Actual speeds
attained depend on your cable operator’s CMTS (Cable Modem
Termination System).
Note: The standard your cable operator supports
determines the maximum upstream and downstream
speeds attainable. Actual speeds attained depend on
the distance from the cable operator’s central office,
noise, and so on.
Network Address
Translation (NAT)
Each computer on your network must have its own unique IP
address. Use NAT to convert your public IP address(es) to
multiple private IP addresses for the computers on your
network.
Port Forwarding If you have a server (mail or web server for example) on your
network, you can use this feature to let people access it from
the Internet.
DHCP (Dynamic Host
Configuration Protocol)
Use this feature to have the ZyXEL Device assign IP addresses,
an IP default gateway and DNS servers to computers on your
network.
Management Use the built in web configurator to configure and diagnose
your ZyXEL Device.
IP Multicast IP multicast is used to send traffic to a specific group of
computers. The ZyXEL Device supports version 1 IGMP
(Internet Group Management Protocol) used to join multicast
groups (see RFC 2236).
Wireless Functionality
(P-974HW Only)
Allow the IEEE 802.11b and/or IEEE 802.11g wireless clients to
connect to the ZyXEL Device wirelessly. Enable wireless
security (WEP, WPA(2), WPA(2)-PSK) and/or MAC filtering to
protect your wireless network.
