FAQsFAQs

Patton's Model 1068 VDSL Modems provide up to 16 Mbps of high speed Ethernet and voice services
between LANs or other network-enabled devices over a single twisted-pair. The Model 1068 is the only
variable-rate asymmetrical/symmetrical standalone modem solution available today. The ability to select
various asymmetrical and symmetrical line rates enables the Model 1068 to satisfy a broad range of
applications. The Model 1068DV's line sharing capabilities allow users to download files from the Internet,
surf the WWW, and answer e-mail messages while talking on the phone or faxing documents.

Other Applications include:

• MTU/MDU Internet Services

• Network Backbones

• Remote Workstations and Equipment

• ISP Last Mile Extension

How is the VDSL connection established?

Four steps are required to establish a communications link between the two Model 1068 Ethernet Extenders
(Local and Remote) and the respective network devices.

1) Connect the 10/100Base-TX devices to the Ethernet port of each 1068 unit.

2) Connect the POTS/ISDN device to the POTS/ISDN port of each 1068 unit (1068DV only)

3) Connect each end of the twisted-pair wire to the Link port of each 1068 unit.

4) Plug the 1068 power supplies into a suitable power source.

5) Plug the output jack of each power supply to the rear power jack of each 1068 unit.

Once powered up, a communications link is established between the two 1068 units and the VDSL LED on
each 1068 unit will glow solid green.

NOTE: If line rates are changed from their original settings, both CO (Central Office) and CP (Customer Premise) units
must be set to the same line rate/dip switch settings.

Does the Model 1068 include any management capabilities or test modes?

No, the Model 1068 does not have any management capabilities or test modes. However, it does feature
seven status LED indicators to provide operational status at a glance and assist with troubleshooting.

Why does the Model 1068 VDSL QOL/error light occasionally flash?

When the QOL/"error” LED flashes it signifies that error correction is taking place and data integrity is
maintained. It is possible for the error light to be constantly lit and the link will still function with data intact.
However, when the QOL/Error LED is continuously lit, the 1068’s are approaching their maximum distance
capabilities under the current environment and line rate. When the QOL is constantly lit, we recommend
switching the modem to a lower line rate to ensure the most reliable connection.

What are the distance limitations of the Model 1068 using different gauge wires?

At the default setting of 12.5 Mbps symmetrical, using 24 AWG (0.5 mm) wire, the Model 1068 is capable of
providing Ethernet extensions up to 4,656 ft (1.42 km) including the potential 328 ft (100 m) Ethernet
connections on both ends of the communications link. Using 26 AWG (0.4 mm) wire, the Model 1068 is
capable of providing Ethernet extensions up to 3,856 ft (1.18 km). Actual distance and link performance will
vary based on the environment (cross talk/noise) and type/gauge of wire used. The chart below shows an
example of how the gauge of wire affects the distance.

Approximate Distances at 12.5 Mbps (Default Setting)

Wire Gauge: AWG (mm) Distance: Feet (km)

26 AWG (0.4 mm) 3856’ (1.18 km)
24 AWG (0.5 mm) 4656’ (1.42 km)

22 AWG (0.64 mm) 5256’ (1.60 km)

20 AWG (0.81 mm) 5556’ (1.69 km)

18 AWG (1.00 mm) 5756’ (1.75 km)

16 AWG (1.29 mm) 5856’ (1.78 km)
