Ethernet over DS3 (Ethernet to DS3) Converters

Valiant offers its Ethernet to DS3 converters (Ethernet over DS3 Converters) packaged in a 19-inch 1U (44mm) high rack-mountable chassis. Provides framed and un-framed DS3 options.

Ethernet to DS3 converters (Ethernet over DS3 Converters) Valiant Ethernet to DS3 converters (Ethernet over DS3 Converters) provides a 100BaseT data interface on the user side which may be used to transport Ethernet traffic over a DS3 link. The converter provides a simple and cost effective method to convert and transport 100BaseT ethernet data over a DS3 link.

Valiant offers its Ethernet to DS3 converters (Ethernet over DS3 Converter) packaged in a 19-inch rack-mountable chassis. Valiant Ethernet to DS3 converters (Ethernet over DS3 Converter) provides a 100BaseT data interface which may be used to transport Ethernet traffic over an DS3 link. The converter provides a simple and cost effective method to convert and transport 100BaseT ethernet data to an DS3 stream. The converter may be accessed by the user for configuration and monitoring through a Windows based GUI that is shipped with the system. It may be also accessed remotely over a TCP-IP network.

Applications:

  • 100 BaseT Ethernet to DS3 Conversion (100BaseT over a DS3 interface)
  • Remote LAN applications
  • Remote LAN over Wireless DS3 application
 


Why we are better:

Our Ethernet over DS3 equipment offers the following necessary features that similar equipment from the other manufacturers do not offer or support......

  • We offer the option of Framed DS3 as well as Un-Framed DS3 option. The framing option is user programmable and use may select the DS3 interfaces as Framed DS3 or Un-Framed DS3.

    Note: Enabling the Framing option becomes essential when you inter-connect and use the equipment over an Sonet/SDH network. If you connect an Un-Framed DS3 interface of the equipment to a Framed DS3 network interface, the network is likely to show an error on the DS3 interface.

  • Our equipment allows the user to connect to, configure and manage the equipment remotely over a TCP-IP network. Most of  the equipment being offered by the competetion does not offer this feature.

  • Our equipent supports efficient handling of data, even during data bursts. Our product design provides a very large buffer data storage capacity to allow for and handle any data bursts very efficiently.

  • Supports Jumbo Frames: Our equipment is equipped with a Committed Information Rate controller (CIR) which manages any data overflows through its 100MHz SDRAM controller which interfaces to a 32-bit wide 128 Mbit SDRAM. The SDRAM is used to buffer the data from the Ethernet and WAN ports for transport. It can accommodate up to 8192 frames with a maximum frame size of 2016 bytes to prevent any data overflows, or loss of packates in the event of a data burst.

    Flow control is a part of basic ethernet communication protocol and the TCP-IP flow control protocol ensures that an optimum flow control is maintained at all times.

    Note # 1: It is essential that the two routers / servers be operating in the same IP domain (subnet), since the Ethernet Over DS3 converter simply interconnects two LANS over a DS3 link. The Ethernet Over DS3 converter does not do any routing function. It simply provides a bridge to inter-connect two LANs over a DS3 link.

    Note: The equipment should always be installed and used in pairs - with each unit to be installed at either end of the DS3 link.
