[. . . ] · WiFi handsets to extend network-based VoIP service throughout the home. Particularly attractive is the use of existing broadband networks (DSL, cable, FTTH) for backhaul to the service provider's core network to reduce costs while delivering more services. But service providers face significant challenges in delivering high-quality voice services over broadband networks and home networks over which they have no control: · Voice calls have no guarantees with retail and unspecified broadband home routers. [. . . ] It automatically detects a routed IP or PPPoE WAN and configures itself. · The service provider device can connect to the VersaLink 7501 via Ethernet cable or as an 802. 11b/g WLAN client. · The VersaLink 7501 automatically identifies the service provider device and assigns an IP address. The 7501 uses this address to identify device-specific traffic. · Wireless push button configuration and 2nd SSID for handsets enable automatic pairing of approved devices with WEP, WPA, or WPA2 security. Handsets may be pre-provisioned with an SSID and security key, or easily paired with push-button or PIN setup. · TR-069 support and remote GUI capabilities enable a truly managed solution. The service provider can remotely configure the 7501 and run diagnostics.

It supports multiple IPSec and VPN tunnels. · On uplink traffic: As a WLAN-connected or LAN-connected voice device sends packets simultaneous with other WLAN clients and LAN devices (e. g. , bandwidth hogs like file transfers or gaming apps), packets from the voice device are identified based on IP address or WMM voice tags. They are prioritized and routed first to the broadband connection. · Packets from other devices that have the same DiffServ value as packets from the voice device can be remarked to a lower DiffServ value, so that voice device traffic can maintain a higher priority on a DiffServ-enabled WAN. · On downlink traffic: Unlike common routers, the 7501 can remark WAN-to- LAN packets based on specific settings such as IP address, port range, or DiffServ. [. . . ] VersaLink provides high-performance 802. 11b/g wireless and routing, four 10/100 Ethernet ports, and a USB host port for printer- and filesharing. For VoWLAN applications, advanced QoS features ensure that voice quality is unaffected by data traffic in the home. With a simple-to-use Web-based interface and built-in setup wizard, WAN auto-detection and LAN network map, the gateway is easily managed. [. . . ]
