XtendLan

The XL-GDB SHDSL access system provides high-speed data access over single-pair copper wires. It can transmit up to 2.304 Mbps V.35 or Ethernet signal without a repeater for more than 7km (24 AWG line) at a Bit Error Rate of less than 10^-7. Using SHDSL transmission technology, the XL-GDB SHDSL network access system allows fiber quality transmission on a single pair of copper wire. Using lower gauge larger copper wire may allow you to attain greater distances.

XL-GDB desktop SHDSL modem is part of the XtendLan SHDSL access system. Used in conjunction with the XL-GDB shelf type CO (Central Office) line card or desktop SHDSL modem, the unit provides repeater less data transport of up to 2.304 Mbps, over a single pair of unconditioned copper wire. Also models with 2-pair transmitions provide rates up to 4.096 Mbps. The rate is automatically adjusted to synchronize at specified rates, corresponding to the distance between the local and remote units. For instance, under the E1 transmission specification, the data rate is software selectable at any of the available Nx64 kbps rates where N is from 3 to 32. More parameters are presented in manual.
