Ethernet over T1 Converters

Product Overview

Orion’s Ethernet over T1 Converter allows the user to send Ethernet data, between two points, over T1 links. T1 Interface is 100 Ohms. Ethernet Interface options may be ordered as 10/100 Base-T Electrical Ethernet or 100Base-FX Optical Ethernet over 850nm/1310nm/1550nm single mode optical fiber.

The equipment be always installed and used in pairs, with one terminal being installed at either end of the T1 link.

The VCL-Ethernet over T1 Converter is an Ethernet extension device utilizing TDM telecom infrastructure (the telecom network of T1, or of PDH, Sonet and T1/DS3/SDH microwave etc. carrying T1). It converts the Ethernet data into T1 frame format for transmission over the existing TDM (T1) link and then re-converts the T1 back into Ethernet data the far-end terminal, to BRIDGE two Ethernet LANs over the existing T1-based telecom network. The device can effectively utilize the existing TDM network to transport Ethernet data with low investment.

Applications

The equipment may be used for the following purposes:

  1. Bridging Ethernet LANs over existing TDM (T1) telecom network.
  2. Extending Ethernet networks utilizing TDM (T1) landline based telecom infrastructure.
  3. Using telecom network of T1/PDH/SDH microwave etc. carrying T1 to transport Ethernet Data.

In all cases the equipment must be always installed and used in pairs, with one terminal being installed at either end of the network.
