4.3 CONNECTING THE TWISTED PAIR INTERFACE

The Model 3088RC supports communication between two DTE devices as follows:

	The interconnecting cables shall be acceptable for
	external use and shall be rated for the proper applica-
CAUTION	tion with respect to voltage, current, anticipated tem-
	perature, flammability, and mechanical serviceability.

Using 24 AWG (0.5 mm) wire up to:

•32,000 feet (9.7 km) at 192 kbps

•18,500 feet (5.6 km) at 2.312 Mbps Using 26 AWG (0.4 mm) wire up to:

•23,000 feet (7 km) at 192 kbps

•13,200 feet (4 km) at 2.312 Mbps 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 Model 3088RC 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 equipment, or standard, ßat modular telephone type cable, are not acceptable.
