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 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 omni 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 TA.

To connect your U-interface omni to your ISDN line complete the steps below:

Connect the RJ-45 connector to the “ISDN U” jack on the omni.

Connect the other end of the RJ-45 cable (or RJ-11) to your wall jack.

S/T Interface

If you have purchased the omni S/T model, you will need an NT-1 device to connect to the network.

To connect your U-interface omni to your ISDN line complete the steps below:

Connect the RJ-45 connector to the “ISDN S/T” jack on the omni.

Connect the other end of the RJ-45 cable (or RJ-11) to your NT-1.
