6.Connect the Ethernet interface (refer to section 3.4, “Connecting the 10/100Base-T Ethernet Interface” on page 12).

3.3CONNECTING THE TWISTED-PAIR LINE INTERFACE

The VLINK modem supports communication between two peer Ethernet LAN sites over a distance of up to 6,000 ft (1.83 km) over 24 AWG (0.5 mm) twisted-pair wire.

Note Actual distance and link performance may vary depending on the environment and type/gauge of wire used.

Follow the steps below to connect the VLINK modem VDSL interfaces.

Note The VLINK modem units work in pairs. One of the units must be a CO (Central Office), and the other unit must be a CP (Cus- tomer Premise). It does not matter which end is the CO and which is the CP. The link is always initiated by the CP. As long as the CO is powered on, the CP can establish a link by being pow- ered on or by having its power reset.

1.To function properly, the two VLINK modems must be connected together using twisted-pair, unconditioned, dry, metal wire, between 19 (0.9mm) and 26 AWG (0.4mm). Leased circuits that run through signal equalization equipment are not acceptable.

2.The VLINK modem is equipped with two interface jacks that can be used on the VDSL interface, an RJ-45 or a terminal block. These VDSL interfaces are a two-wire interface. Observe the signal/pin rela- tionships on the VLINK modem's VDSL interface jacks.

The RJ-45 connector on the VLINK modem's twisted pair interface is polarity insensitive and is wired for a two-wire interface. The signal/pin relationship is shown in Figure 4.
