Ethernet over DS3 (Ethernet to DS3) Switch

Product Overview

Orion Telecom Networks Inc. 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
  • 3x + 1x100Base-FX full duplex optical ethernet interface 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: 1500 bytes (max)
  • Accommodates up to 8192 frames with a maximum frame size of 1500 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...

  • We offer the option of Framed DS3 as well as Un-Framed DS3 option. The framing option is user programmable and use may select the DS3 interfaces as Framed DS3 or Un-Framed DS3.

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.

  • 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 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.
