VPN
Establish a Virtual Private Network (VPN) to connect with business partners and branch
offices using data encryption and the Internet to provide secure communications without the
expense of leased site-to-site lines. The Prestige VPN is based on the IPSec standard and is
fully interoperable with other IPSec-based VPN products.
DHCP (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has
built-in DHCP server capability, disabled by default, which means it can assign IP addresses,
an IP default gateway and DNS servers to all systems that support the DHCP client.
SNMP
SNMP (Simple Network Management Protocol) is a protocol used for exchanging
management information between network devices. SNMP is a member of the TCP/IP
protocol suite. Your Prestige supports SNMP agent functionality, which allows a manager
station to manage and monitor the Prestige through the network.
Firmware Upgradeable
The firmware of the Prestige can be upgraded via the web configurator.
1.3 Applications
Here are some examples of what you can do with your Prestige.
1.3.1 Internet Access
The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/
IP protocol, which the Internet uses exclusively. It is compatible with all major DSL DSLAM
(Digital Subscriber Line Access Multiplexer) providers. A DSLAM is a rack of DSL line cards
with data multiplexed into a backbone network interface/connection (for example, T1, OC3,
DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack for SHDSL.
