Connecting the 10/100Base-T Ethernet Port to a Hub
The Model 1068 10/100Base-T interface is configured as DTE (Data Ter- minal Equipment), just like a 10/100Base-T network interface card in a PC. Therefore, it “expects” to connect to a 10/100Base-T Hub using a straight-through RJ-45 cable. Figure 7 diagrams the cable wiring for con- necting the Model 1068 to a 10/100Base-T hub.

Connecting the 10/100Base-T Ethernet Port to a PC (DTE)
The Model 1068 10/100Base-T interface is configured as DTE (Data Ter- minal Equipment). If you wish to connect the 1068 to another DTE devices such as 10/100Base-T network interface card in a PC (or 1068s in a back-to-back arrangement), you must construct a 10/100Base-T crossover cable as shown in Figure 8.

2 | (TX-) | 2 (TX-) |
3 | (RX+) | 3 (RX+) |
6 | (RX-) | 6 (RX-) |

3.5 CONNECTING THE POTS/ISDN LINE
The RJ-45 port labeled “POTS/ISDN” is the POTS/ISDN interface. A tele- phone or an ISDN device may be connected to this port and carried over the VDSL line. The units do not need power for the POTS interface to
