SpeedStream® 4200 Specifications and Technical Details

Technical Specifications

SpeedStream® 4200 Circuit Board Bridging
  • RFC 2684 (formerly 1483) Bridged Ethernet over ATM PVCs
  • IEEE 802.1d transparent, learning bridge
  • Dynamic learning of up to 255 addresses
  • Spanning Tree Algorithm
AAL and ATM Support
  • Precise Peak Cell Rate traffic shaping on a per-VCC basis
  • Up to 8 active VCCs across VPI 0-255
  • VCI 0-65535 address range
  • ATM Forum UNI3.1/4.0 PVC
  • OAM F4/F5
Media Interface
  • RJ-11 ADSL connection
  • 10/100 Base-T RJ-45 Ethernet connection
  • Auto-MDI/X
  • Standard USB connection (4200 model only)
Features and Benefits
  • Web-based (HTTP) configuration of PPPoE parameters allows easy deployment (PPPoE Modems and Routers)
  • 10/100 Ethernet provides full-rate LAN performance.
  • Features simultaneous Ethernet and USB connectivity, allowing two PCs with discrete IP addresses or PPPoE clients to share a DSL line
  • Up to 24 Mbps downstream and 1.5 Mbps upstream provides true broadband experience for subscribers. (I would question it's ability to achieve ths speed personally!)
  • Support for G.lite and full-rate ADSL, ADSL2, ADSL2+ and RE-ADSL ensure compatibility with most DSL networks.
  • Concurrent NAT and NAPT (Routers only)
  • WHQL (Windows Hardware Quality Labs) certified, ensuring plug-and-play USB installation on any PC running Window® 2000, Me, or XP
  • Password protection prevents unauthorized users from modifying the Router’s configuration settings.
  • Firewall security with four conveniently pre-set standard levels of security (Off, Low, Medium, High), an ICSA-compliant mode, and a custom setting for advanced users.
  • Universal Plug and Play (UPnP) allows automatic discovery and configuration of the SpeedStream Router. UPnP is supported by Windows Me, XP, or later, operating systems.
  • One computer on your local network can be configured to allow unrestricted two-way communication with servers or individual users on the Internet. This provides the ability to run programs that are incompatible with firewalls.
  • Port Forwarding provides flexibility by allowing you to change internal IP addresses without affecting outside access to your network. (Does not work well for VoIP!)

About the AR7 Chipset

AR7 ChipThe Texas Instruments AR7 device (TNETD7300) is a fully integrated single-chip Asymmetric Digital Subscriber Line (ADSL) bridge/router solution, integrating a broadband communications processor and peripherals, ADSL physical layer, ADSL line driver, USB physical layer, Ethernet physical layer and power management for use in Customer Premise Endpoint (CPE) modems for residential and small-office applications. The TNETD7300 can be used in modems ranging from simple Ethernet bridges to integrated access devices (IADs) and Residential Gateways.

The TNETD7300 includes features to enhance ADSL throughput when connected to a compatible central office ADSL modem. ADSL+ provides downstream transmission rates far beyond the 12Mb/s limit of S=1/2. Extended-Reach (ERADSL) and All Digital Loop ADSL allow 384-kb/s/128-kb/s service to be provided on loops as long as 6.4km. These features allow the TNETD7300 to greatly surpass the downstream throughput limit of 8 Mb/s and the 5.3km reach limits generally seen in previous ADSL modems, thus granting ADSL service providers access to a larger subscriber pool without requiring replacement of the local loop infrastructure.

The TNETD7300 includes a new VLYNQ™ peripheral bus extension that allows VLYNQ-enabled devices to be gluelessly interfaced to TNETD7300 for advanced applications such as voice-over-packet (VOP) telephony or ADSL-to-WLAN (802.11) bridging and interfaces such as USB 2.0 and PCI.
