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: La fiche ISDN est destinée uniquement pour la connexion 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. 8
