U models include a built-in NT1. Optional external ISDN S/T Terminal
Equipment may share the telephone's ISDN line by connecting to the
S/T jack on the telephone.

If you are not using external Terminal Equipment, no termination switch
setting is required.

Set the Termination Switch on the Telephone

If external Terminal Equipment (TE) is connected, set the termination
switch on the bottom of the telephone to match the termination
impedance to your premises wiring configuration. Two typical wiring
configurations for connecting external TE are shown below, with the
appropriate switch settings.

Available switch settings are 50
and 100 ohms.

We recommend the use of Category 3 or better unshielded twisted pair
cable with T568A or T568B connector wiring. Distances shown are the
maximums for 24-gauge cable, and may vary for other cable types.
