Ethernet to E3 (Ethernet over E3) Converters
Valiant offers its
Ethernet to E3 converters (Ethernet over E3 Converters) packaged in a 19-inch
rack-mountable chassis. Provides framed and un-framed E3 options.
Valiant Ethernet to E3 converters (Ethernet over E3 Converters)
provides a 100BaseT data interface on the user side which may be used to transport
Ethernet traffic over a E3 link. The converter provides a simple and cost effective method
to convert and transport 100BaseT ethernet data over a E3 link.

Valiant Ethernet to E3 converters (Ethernet
over E3 Converters) provide a 100BaseT data interface which may be used to transport
Ethernet traffic over an E3 link. The converter provides a simple and cost effective
method to convert and transport 100BaseT ethernet data to an E3 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. |

Why we are better:
Our Ethernet over E3 equipment offers the following necessary features that similar
equipment from the other manufacturers do not offer or support......
We offer the option of Framed E3 as well as
Un-Framed E3 option. The framing option is user programmable and use may select the E3
interfaces as Framed E3 or Un-Framed E3.
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 E3 interface of the
equipment to a Framed E3 network interface, the network is likely to show an error on the
E3 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 equipment 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 E3 converter simply interconnects two LANS over a
E3 link. The Ethernet Over E3 converter does not do any routing function. It simply
provides a bridge to inter-connect two LANs over a E3 link.
Note: The equipment should always be installed and used in pairs - with each unit to be
installed at either end of the E3 link.
