Ethernet over E3 Switch (Ethernet over E3)

Product Overview

Orion Telecom Networks Inc. offers its Ethernet to E3 Switch (Ethernet over E3 Switch) packaged in a 19-inch rack mountable chassis.

Orion Ethernet to E3 Switch (Ethernet over E3 Switch) 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 Switch (Ethernet over E3 Switch) packaged in a 19-inch 1U (44mm) high rack-mountable chassis.

Orion Ethernet to E3 Switch (Ethernet over E3 Switch) 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 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.

  • 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 1500 / 1968 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 Switch simply interconnects two LANS over a E3 link. The Ethernet over E3 Switch 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.
