facture, garantie, date d'achat ?

dans le titre tu parles de switch.
modifies le titre ou ton matos vendu pour que ca reste coherent

facture oui probablement mais il a deux ans donc sans garantie, 1ere main (si vous faites une recherche dans le forum j'en ai acheté un autre pour un ami d'occasion mais celui-là était neuf).
Zyxel c'est Zyxel, c'est le top et çà tombe rarement en panne.

Features of the Prestige 642R
 
Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.
 
�� High Speed Internet Access
The P642 ADSL router can support downstream transmission rates of up to 8Mbps and upstream
transmission rates of 640Kbps. The P642 also supports rate management; rate management allows ADSL
subscribers to select an Internet access speed that best suits their needs and budgets.
 
�� PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a Dial-Up connection. It allows your ISP to use
their existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver
on the Prestige is transparent to the PCs on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual PCs.
 
�� Transmission Rate Standards
♦ Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2)) 1.
♦ Full-Rate (ANSI T1.413, Issue 2; G.dmt(G.992.1)) with line rate support of up to 8Mbps
downstream and 1024kbps upstream.
♦ G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream.
 
�� 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 Multicast
Traditionally, IP packets are transmitted in two ways: unicast or broadcast. Multicast is a third way to
deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to
support multicast groups. The latest version is version 2 (see RFC2236). Both versions 1 and 2 are
supported by the Prestige
 
�� 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.
 
�� 10/100M Fast Ethernet LAN Interface
The P642's 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or
100Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
 
�� 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 the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has the built-in DHCP
Server enabled by default. DHCP Relay allows the Prestige to act as a surrogate DHCP server where it
relays IP address assignment from the actual DHCP server to its clients.
 
�� Multiple PVC (Permanent Virtual Circuits) Support
Your Prestige supports up to 8 PVC’s.
 
�� Networking Compatibility
Your Prestige is compatible with the major ADSL DSLAM (Digital Subscriber Line Access Multiplexer)
providers, making configuration as simple as possible for you.
 
�� Multiplexing
The Prestige 642R Series supports VC-based and LLC-based multiplexing.
 
�� Encapsulation
The Prestige 642R Series supports PPP (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM, MAC encapsulated routing as well as PPP over Ethernet (RFC 2516).

�� 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 IP account. SUA supports popular Internet applications 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.
 
�� Filters
The Prestige's packet filtering functions allows added network security and management.
 
�� Ease of Installation
Your Prestige is designed for quick, intuitive and easy installation.
 
�� Housing
Your Prestige's all new compact, ventilated housing minimizes space requirements making it easy to
position anywhere in your busy office.
