Protocols Supported
TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
PPP (Point-to-Point Protocol) link layer protocol.
SUA™ (Single User Account) and NAT (Network Address Translation).
Multiple Protocol Support
♦ Novel IPX (Internetwork Packet eXchange) network layer protocol.
♦ Transparently bridging for unsupported network layer protocols.
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows you to automatically assign TCP/IP settings to
workstations on your network. Your P681 can act as a DHCP Server or as a surrogate DHCP server
(DHCP Relay) where it relays IP address assignment from the actual DHCP server to the clients.
Networking Compatibility
Your Prestige is compatible with the major SDSL DSLAM (Digital Subscriber Line Access Multiplexer)
providers including Ascend/Lucent and Copper Mountain, making configuration as simple as possible for
you.
Encapsulation
The Prestige 681 supports RFC 1490 (Multiprotocol over Frame Relay) and PPP over HDLC (RFC 1662)
encapsulation. Please see section 4.6 for more information on specific encapsulation methods.
NAT/SUA for single-IP-address Internet Access
The Prestige's SUA (Single User Account) feature allows multiple user Internet access for the cost of a
single ISP account. SUA supports popular Internet application, such as MS traceroute, CuSeeMe, IRC,
RealAudio, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.
Full Network Management
♦
SNMP (Simple Network Management Protocol) support.
♦
Accessing SMT (System Management Terminal) through a telnet connection
♦
Windows based PNC (Prestige Network Commander)
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure since the password is scrambled prior to transmission.
However, PAP is readily available on more platforms.
