Before you begin:
Verify that the following items came with your DSL kit:
Documentation
R-11 DSL cable
RJ-45 Ethernet cable
straight-through
RJ-45 crossover
(Xover) Ethernet cable
Line filter(s)PCI Ethernet adapter
Wall-mount line filter
Power supply
Two-to-one adapter(s)
Your service provider may include a wall-mount filter, two-to-one adapter(s), line filter(s), and an Ethernet
adapter in your DSL kit. If you received any of these items, follow the instructions provided in this guide for

Two-to-One Adapter
If your DSL modem and another device will share the same phone jack, install a two-to-one adapter:
1. Plug adapter into the phone jack.
2. Plug a line filter into one of the sockets of
the two-to-one adapter. The other socket will
be used to connect the DSL cable.
3. Plug the telephone (or other device) cord
into the line filter.
For each device that shares the DSL phone number:
1. Unplug the device’s cord from the phone jack.
2. Plug the filter into the phone jack.
3. Plug the phone cord (or other device cord)
into the filter.
