Operation Manual

1.3 The DC-214/216 ADSL Homestation Features

The DC-214/216 ADSL Homestation provides the following features:

ADSL Multi-Mode Standard: Supports downstream transmission rates of up to 8Mbps and

upstream transmission rates of up to 1024Kbps. 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)).

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 ISP. The product

also supports VC-based and LLC-based multiplexing.

Network Address Translation (NAT): Allows multi-users to access outside resource such

as Internet simultaneously with one IP address/one Internet access account. Besides, many

application layer gateway (ALG) are supported such as web browser, ICQ, FTP, Telnet, E-

mail, News, Ping and others.

Domain Name System (DNS) relay: Provides an easy way to map the domain name (a

friendly name for user such as www.yahoo.com) and IP address. When local machine sets

its DNS server with this router’s IP address. Then every DNS conversion request packet

from the PC to this router will be forwarded to the real DNS in outside network. After the

router gets the reply, then forwards it back to the PC.

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 for one access account. No PPPoE client software

is required for local computer. The Automatic Reconnect and Disconnect Timeout (Idle

Timer) functions are provided, too.

Virtual Server: User can specify some services to be visible from outside users. The router

can detect incoming service request and forward it to the specific local computer to handle

it. For example, user can assign a PC in LAN acting as WEB server inside and expose it to

the outside network. Outside user can browse inside web server directly while it is protected

by NAT. A DMZ host setting is also provided to a local computer exposed to the outside

network, Internet.

Bridge Filtering: Filters the packet based on MAC address. It will increase the performance

in LAN and WAN, also provide a higher-level security control.

Dynamic Host Control Protocol (DHCP) client and server: In the WAN site, the DHCP

client can get an IP address from the Internet Server Provider (ISP) automatically. In the

LAN site, the DHCP server can allocate multiple clients IP addresses and distribute them

including IP address, subnet mask as well as DNS IP address to local computers. It provides

an easy way to manage the local IP network.

Web based GUI: Supports user-friendly web based GUI for configuration and management.
