Product Overview |
 |
Orion offers its Ethernet to DS3 converters
(Ethernet over DS3 Converters) packaged in a 19-inch 1U (44mm) high
rack-mountable chassis.
Orion 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.

transport Ethernet traffic over a DS3 link. The converter provides a simple
and cost effective method to convert and transport 100BaseT Ethernet data to
a 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.
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......
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 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 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. |
