Once the Model 3088 is properly conﬁgured, it is ready to connect to the

twisted pair interface, to the serial port, and to the power source. This

section tells you how to make these connections.

The Model 3088 supports communication between two DTE devices

as follows:

Using 24 AWG (.5 mm) wire:

• up to 32,000 feet (9.7 km) at 192 kbps

• up to 18,500 feet (5.6 km) at 2.312 Mbps on

Using 26 AWG (.4 mm) wire:

• up to 23,000 feet (7 km) at 192 kbps

• up to 13,200 feet (4 km) at 2.312 Mbps on

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 3088 needs one twisted pair of

metallic wire. This twisted pair must be unconditioned, dry, metallic

wire, between 19 (.9mm) and 26 AWG (.4mm) (the higher number

gauges will limit distance). Standard dial-up telephone circuits, or

leased circuits that run through signal equalization equipment, or

standard, ﬂat modular telephone type cable, are not acceptable.
