1.3 Technical Features
Technical charateristics of WebShare 111U:
• ADSL Multi-Mode Standard: supports downstream rates of up to 24
Mbps and upstream rates of up to 1 Mbps. It also supports rate
management that allows ADSL subscribers to select an Internet access
speed suiting their needs and budgets. It is compliant with Multi-Mode
standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2)), G.hs
(G994.1), G.dmt.bis (G.992.3), G.dmt.bisplus (G.992.5)). The Annex A and
B are supported in different H/W platforms.
• Multi-Protocol to Establish A Connection: Supports PPPoA (RFC 2364
- PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM
(bridged or routed), PPP over Ethernet (RFC 2516) and IPoA (RFC1577) to
establish a connection with the ISP. The product also supports VC-based
and LLC-based multiplexing.
• Dual-Port Modem/Router: A 10/100Mbps fast Ethernet router is built
in with automatic switching between MDI and MDI-X for 10Base-T and
100Base-TX ports. An Ethernet straight or cross-over cable can be used
directly for auto detection.
• Network Address Translation (NAT): Allows multi-users to access
outside resources such as the Internet simultaneously with one IP
address/one Internet access account. Many application layer gateway
(ALG) are supported such as web browser, ICQ, FTP, Telnet, E-mail, News,
Net2phone, Ping, NetMeeting, IP phone and others.
• Firewall: Supports simple firewall with NAT technology and provides
option for blocking access from Internet, like Telnet, FTP, TFTP, WEB,
SNMP and IGMP.
• Domain Name System (DNS) relay: Provides an easy way to map the
domain name (a friendly name for users such as www.yahoo.com) and IP
address. When a local machine sets its DNS server with this router’s IP
address, every DNS conversion request packet from the PC to this router
will be forwarded to the real DNS in the outside network.
• PPP over Ethernet (PPPoE): Provides embedded PPPoE client function
to establish a connection. Users can get greater access speed without
changing the operation concept, sharing the same ISP account and paying
