i2022 ISDN Teleset

In the following application, the NT1 is equal in distance to both i2022 phones. The Terminating Resistors are set to “On” at one of the phones and at the NT1.

i2022 EQUIPPED WITH A U INTERFACE MODULE

The i2022 is available with an optional U Interface Module. Actually, the U Interface Module is an NT1 device, therefore, the Teleset does not require an external NT1 device. Fig. 9 shows the i2022 equipped with a U Interface Module. The U Interface is connected to the power adapter. The U Interface and power connection cable is connected to the “Line-In” jack located on the U Interface Module in the rear of the Teleset.

TERMINATING RESISTORS

The i2022Teleset U Interface module has built-in Terminating Resistors. The Terminating Resistor switches are located on the top of the Interface Module.

NOTE: The Interface Module must be removed from the Teleset to gain access to the switches.

When the switches are in the On position, the Terminating Resistors are installed. The value of the resistors is 100 Ohms.
