Features
Voice over IP compliance with SIP standard
The router supports cost-effective, toll-quality voice calls over the Internet. It complies with the most popular
industrial standard, SIP protocol, to ensure the interoperability with SIP devices and major VoIP Gateways.
The VoIP ADSL router supports call waiting, silence suppression, voice activity detection (VAD), comfort noise
generation (CNG), line echo cancellation, caller ID (Bell 202, V3) and so on.
Lifeline Support
The router integrates RJ-11 FXO port for inbound and outbound calls transmitted through the PSTN. Users
can receive phone calls from the PSTN while enjoying VoIP call service at the same time. In addition, the
device automatically falls back to lifeline POTS to enable making normal phone calls when there is a power
outage, or when the Internet connection is down.
Express Internet Access
The router complies with ADSL worldwide standards. It supports downstream rate up to 12/24 Mbps with
ADSL2/2+, 8Mbps with ADSL. Users enjoy not only high-speed ADSL services but also broadband multimedia
applications such as interactive gaming, video streaming and real-time audio more easily and faster than ever.
It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (ITU G.992.1); G.lite (ITU G.992.2);
G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3); G.dmt.bisplus (ITU G.992.5)).
802.11g Wireless AP with WPA Support
With an integrated 802.11g Wireless Access Point in the router, the device offers quick and easy access to
wired networks, wireless networks and broadband connections (ADSL) with single device simplicity, and as a
result, mobility to users. In addition to 54 Mbps 802.11g data rate, it also interoperates backwardly with
existing 802.11b equipment. The Wireless Protected Access (WPA) and Wireless Encryption Protocol (WEP)
supported features enhance the security level of data protection and access control via Wireless LAN.
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI and MDI-X for
10Base-T and 100Base-TX ports. An Ethernet straight or crossover cable can be used directly for auto
detection.
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.
Quick Installation Wizard
Supports a WEB GUI page to install the device quickly. With this wizard, end users can enter the information
easily which they get from their ISP, then surf the Internet immediately.
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices and PCs from many
different vendors. It makes networking simple and affordable for users. UPnP architecture leverages TCP/IP
and the Web to enable seamless proximity networking in addition to control and data transfer among
networked devices. With this feature enabled, users can now connect to Net meeting or MSN Messenger
seamlessly.
