Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

Product Highlights

  • Description

    4-Port T1/E1 Ethernet Network Extender Kit


    Quick Facts

  • Kit includes two extenders.
  • Bridges 10BASE-T/100BASE-TX Ethernet across four T1/E1 lines.
  • Dual Ethernet ports.
  • Supports Fractional T1/E1 in framed and unframed mode.

  • Further Details

  • Supports speeds up to 6.144 Mbps on T1 and 7.936 Mbps on E1.
  • Autosensing, autonegotiating 10-/100-Mbps LAN connections.
  • Auto MDI/MDI-X means you never need a crossover cable on the Ethernet side.
  • RS-232 console port for configuration.
  • Line build-out (LBO) capability.

  • The pair of extenders included with this kit act as a bridge, enabling you to link two Ethernet networks across four T1/E1 lines. Because you’re using leased lines provided by your telco, there are no distance limitations—you can extend your network anywhere you can get a T1 line.

    The T1/E1 Ethernet Network Extender converts protocols and data from Fractional T1/E1 to 10BASE-T/100BASE-TX Ethernet and supports both framed and unframed modes with line codes.

    The extenders multiplex data onto all four lines and automatically maintain the connection if a T1/E1 line goes down. When the line comes back into service, the extenders automatically restore it.
