Multiple ISDN Devices
If the NT1 is connected to more than one ISDN device, follow the appropriate procedure below.
75 meters or more
If the connection spans 75 meters (250 feet) or more, set the DIVA T/A 100 Ω switch to the On position. Set the other ISDN devices to 100 Ω of resistance, and the NT1 to no resistance. Consult the manuals provided with the other ISDN devices and NT1 for more detailed instructions.
Note: Some NT1s do not support connections over 75 meters (250 feet). Check your documentation to determine the distance supported.
75 meters or less
If the connection spans less than 75 meters (250 feet), set the DIVA T/A 100 Ω switch to the Off position, and set the NT1 to 50 Ω of resistance. Set the other ISDN devices to no resistance. Consult the manuals provided with the NT1 and other ISDN devices for more detailed instructions.
