Before you begin, you will need the following in addition to the ISDN LAN Modem
which was provided in the package:
If you have the ISDN LAN Modem with an S/T interface you received an RJ-45
(8-pin) to RJ-45 (8-pin) cable labeled ISDN. If you have the ISDN LAN Modem
with a U interface you received an RJ-11 (6-pin) to RJ-45 (8-pin) cable labeled
ISDN.
10BASE-T Ethernet cable (8-pin to 8-pin connectors) labeled Ethernet which
was provided in the package. It is recommended that you use the cable
provided. If, however, you choose to use another cable it must be a
straight-through 10BASE-T Ethernet cable. It cannot be a crossover cable.
Power adapter provided (you must use the power adapter provided in the
package for your geographic area).
To install the ISDN cable:
1 Connect the RJ-45 (8-pin) connector end of the ISDN cable to the port labeled
ISDN on the back panel, as shown in Figure 13.

2 Connect the opposite end of the ISDN cable into an ISDN wall box that contains
an NT1 if you have the S/T version of the ISDN LAN Modem. If you have the U
version, you do not need an NT1 (one is provided in the LAN Modem); simply plug
the opposite end of the ISDN cable into the wall outlet.
