Ethernet over DS3 (Ethernet to DS3)
Switch |
|
Product Overview
Orion offers its Ethernet over DS3 Switch (Ethernet to DS3 Switch)
packaged in a 19-inch rack-mountable chassis.
Orion Ethernet over DS3 Switch (Ethernet over DS3 Switch) provides
a four 100BaseT Ethernet and 100Base-FX optical ethernet interfaces on
the user side which may be used to transport Ethernet traffic over a
DS3 link. Both ethernet interfaces may be used simultaneously. The
Switch provides a simple and cost effective method to convert and
transport ethernet data over an DS3 link.
Features and Highlights
- Ethernet interface to DS3 45 Mbps converter
4x100BaseT full duplex fast ethernet
interface in accordance with IEEE802.3

Framed and un-framed DS3 options
available
Local and Remote access and
monitoring with either RS232 or 10/100BaseT for remote management
over TCP-IP network
Power Supply: - 48 V DC or 110 V AC
power supply options available.
Ethernet frame size: 2016 bytes (max)
Supports Jumbo Frames
Accommodates up to 8192 frames with a
maximum frame size of 2016 bytes
Prevents any data overflows, or loss of
packets in the event of a data burst.
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. |
Applications
100 BaseT Ethernet and 100Base-FX optical to DS3 conversion
(Ethernet over DS3).
Indications and Alarm Monitoring
Loss of DS3 frame (in framed DS3
mode)
