Your P-870M-I Series (“P-870M-I”) is a VDSL2 modem.
VDSL2 provides high-speed Internet access up to 100 Mbits
per second (each way) through a telephone line. As a result,
your P-870M-I is an ideal modem for Triple Play services,
such as voice, video, high definition television (HDTV), and
interactive gaming.

The P-870M-I Series consists of the following models:

• P-870M-I1, a VDSL2 modem for regular (POTS) lines

• P-870M-I3, a VDSL2 modem for ISDN lines

Make the following connections to set up your P-870M-I.

1 Use a telephone wire to connect the P-870M-I DSL port to

the DSL (or MODEM) port on a splitter. If you do not have
a splitter, connect the DSL port directly to the telephone
jack.

2 Use an Ethernet cable to connect the P-870M-I

ETHERNET port to the computer.

3 Use the included power adaptor to connect the P-870M-I

POWER socket to an appropriate power source.

4 After you’ve made these connections, push in the power

button.

If the POWER, ETHERNET, and VDSL lights are on (or
blinking), you have set up the P-870M-I correctly. Test your
Internet connection by visiting http://www.zyxel.com (or
another web site).

If the lights behave differently or if you cannot connect to the
Web site, make sure the connections are correct. If the lights
are still different, turn off the device, wait a few seconds, and
turn it on again. If the problem continues, contact your local
vendor.

2 Drill two holes for the screws (M3*10). The centers of the

holes should be 108 mm apart.

the wall when drilling holes for the screws.

small gap of about 0.5 cm between the heads of the
screws and the wall.

with the connection cables.
