Getting To Know Your Prestige  
         1-3 
 
Dynamic DNS Support 
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing 
the host to be more easily accessible from various locations on the Internet. You must register for this 
service with a Dynamic DNS service provider. 
 
Multiple PVC (Permanent Virtual Circuits) Support 
Your Prestige supports up to 8 PVC’s. 
 
ADSL Transmission Rate Standards 
♦  Full-Rate (ANSI T1.413, Issue 2; G.dmt (G.992.1) with line rate support of up to 8 Mbps 
downstream and  832 Kbps upstream. 
♦  G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream. 
♦  Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.lite (G992.2)). 
♦  TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol. 
♦  ATM Forum UNI 3.1/4.0 PVC. 
♦  Supports up to 8 PVCs (UBR, CBR, VBR). 
♦  Multiple Protocol over AAL5 (RFC 1483). 
♦  PPP over AAL5 (RFC 2364). 
♦  PPP over Ethernet over AAL5 (RFC 2516). 
♦  RFC 1661.  
♦  PPP over PAP (RFC 1334). 
♦  PPP over CHAP (RFC 1994). 
 
Protocol Support 
♦  DHCP Support 
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to 
obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has 
built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default 
gateway and DNS servers to DHCP clients. The Prestige can now also act as a surrogate 
DHCP server (DHCP Relay) where it relays IP address assignment from the actual real DHCP 
server to the clients. 
♦  IP Alias 
IP Alias allows you to partition a physical network into logical networks over the same 
Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical 
Ethernet interface with the Prestige 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.   
♦  PPP (Point-to-Point Protocol) link layer protocol. 
♦  Transparent bridging for unsupported network layer protocols.
