With these extenders, you can increase connections from the demarc to equipment in your building, and save money by linking remote PBXs over existing dry copper. If you’re a service provider, you can use the extenders to reach a larger subscriber base with less copper and at longer distances—without the need for repeaters.
Plus, they’re easy to set up and use, delivering TDM circuit extension with no configuration. Just take them out of the box, place them on opposite sides of the dry copper, and plug in your T1 or E1 line. The circuit is now ready for communications. Because the two active pins on the extenders’ RJ-45 connector are polarity sensitive, you don’t even have to worry about which wire is connected to the line interface.
Intuitive LEDs alert you to any possible line or circuit problems. For instance, a solid green Link LED indicates a good end-to-end link, and a solid green Frame LED indicates valid framing on the link. For further troubleshooting, the T1 Extenders for Copper also feature a V.52 511/511E pattern generator that enables you to run Remote Digital Loopback (RDL) and Local Analog Loopback (LAL) line tests.
