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).

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.
• RIP I/RIP II
• IGMP Proxy
