Caution: Never connect your ISDN TA to a standard analog
telephone jack or an external NT1 device.
Note: Your phone company may have installed an RJ-45 wall
outlet. The RJ-45-to-RJ-11 that came with your ISDN TA will
work with the RJ-11 end plugged into the wall outlet. However,
multiple phone lines are not supported through the ISDN interface.

Connecting Analog Equipment to Your ISDN TA
You can connect analog equipment (such as a touch-tone phone,
answering machine, or fax machine) to your ISDN TA and use them on
your ISDN line even while you are online.
Note: To find out how to set up supplementary services for these
analog devices (such as Call Waiting or Caller ID), see the chapter
“Voice Features.”
To install an analog device:
1
Insert one end of a standard phone cable (RJ-11) into one of the
ports on the back of the ISDN TA labeled with the picture of a
telephone, as shown in Figure 2-6.
You must provide a standard phone cable (RJ-11) for each analog
device you want to install.
2
Insert the other end of the phone cable into the appropriate jack on
the analog device, as shown in Figure 2-6.
3
Repeat steps 1 and 2 to connect another analog device.
Note: Two phone lines are supported through the Analog Device
Ports.
