Connecting the TA128 to Your ISDN Line

The TA128 comes with a choice of two types of ISDN line
interfaces:
S/T interface - This can only connect to your NT-1 (Network
Termination) device.
Warning: Do not under any circumstances connect directly to the ISDN
wall jack.
U interface - This allows you to connect directly to your ISDN
wall jack.
Warning: The ISDN jack is for ISDN line connection only. Connection of a
phone line may result in damage to your Terminal Adapter.
Attention:
sur une ligne RNIS. La connexion sur une ligne téléphonique
peut endommager votre adaptateur de terminal.

U Interface Model

If you have purchased the TA128 U-interface model, you can
connect the U-Interface directly to the wall jack.
In most cases, the ISDN jack installed by the phone company is a
RJ-11 jack (except in Canada, where RJ-45 jack will be installed),
and the U-Interface jack on the back of the TA128 is a RJ-45 jack.
A RJ-45 to RJ-45 (or RJ-11 to RJ-45, depends on your regional
distributor's request) phone cable is included with your TA128.
To connect the TA128 to your ISDN line:
Connect the RJ-45 connector to the "ISDN U" jack on the
back of the TA128.
Connect the other end of the RJ-45 cable (or RJ-11) to your
wall jack.
