Product Overview |
 |
Orion offers its Ethernet to E3 converters
(Ethernet over E3 Converters) packaged in a 19-inch rack mountable chassis.
Orion 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.
Orion offers its Ethernet to
E3 converters (Ethernet over E3 Converters) packaged in a 19-inch 1U (44mm)
high rack-mountable chassis.
Orion 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......
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 competition 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 packets 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. |
