3.1 CONNECTING THE DSL INTERFACE

The LB510A-R2 supports communication between two DTE devices as follows.

Using 24 AWG (0.5 mm) wire up to:

•18,000 feet (5.48 km) at 192 kbps

•11,000 feet (3.5 km) at 5696 kbps Two things are essential:

1.These units work in pairs. Both units at the end of the twisted pair DSL span must be set for the same DTE rate—one unit set as CO, the other as CP.

2.To function properly, the LB510A-R2 needs one twisted pair of metallic wire. This twisted pair must be unconditioned, dry, metallic wire, between 19 (0.9mm) and 26 AWG (0.4mm) (the higher number gauges will limit distance). Standard dial-up telephone circuits, or leased circuits that run through signal equalization equip- ment, or standard, flat modular telephone type cable, are not acceptable.
