The Rutenbeck ISDN termination resistor, type 681072, is a 100-Ohm single resistor specifically designed for use in ISDN termination boxes and UAE connection boxes. It serves as a termination resistor in the ISDN network to ensure signal quality and prevent reflections at the end of the line. Compliance with the prescribed termination impedance is essential for stable and error-free data transmission in the ISDN network. The resistor is designed for use in telecommunications technology, particularly in connection boxes, where it ensures the electrical termination impedance of the ISDN line.

Applications

The ISDN termination resistor is used in ISDN connection boxes and UAE connection boxes to electrically terminate the line. This is necessary to minimize signal reflections that could lead to transmission errors. The resistor is used in the field of analog and digital telephony, particularly with ISDN basic rate interfaces (BRI), where the termination impedance is standardized at 100 Ohm. The application typically occurs during the installation or maintenance of telecommunications systems by qualified personnel.

Functions and Features in Detail

The resistor has a nominal value of 100 Ohm with a tolerance of +/- 5 %. This means the actual resistance value can range between 95 and 105 Ohm, which is within the technical specifications for ISDN connections. The power dissipation is 0.33 Watt, sufficient to handle thermal load under normal operating conditions.

Technology Explained Simply

An ISDN termination resistor is used to electrically terminate the line at the end to compensate for the cable's impedance. For ISDN connections, the prescribed impedance is 100 Ohm. Without a termination resistor, signals can be reflected at the end of the line, leading to interference, distortion, or data loss. The 100 Ohm resistor ensures the line is closed and signals are transmitted correctly. The tolerance of +/- 5 % is sufficient for operation in the ISDN network, as systems are designed to tolerate a certain deviation. The power rating of 0.33 W is sufficient to handle thermal load under normal use.

Compatibility and Accessories

The resistor is designed for use in ISDN termination boxes and UAE connection boxes. It is specifically designed for use in telecommunications systems that support ISDN basic rate interfaces (BRI). It is typically used as a single component within the connection box.

Mounting and Installation

Installation is typically carried out within the ISDN or UAE connection box. The installation is performed by qualified personnel during the mounting of the connection box or during maintenance work. No additional tools or components are required, as the resistor is designed as a single unit.

Advantages in Operation

Using the Rutenbeck ISDN termination resistor ensures stable and error-free signal transmission in the ISDN network. Compliance with the required impedance of 100 Ohm minimizes signal reflections and interference, thereby increasing the reliability of telephony and data transmission. The tolerance of +/- 5 % and power dissipation of 0.33 W are sufficient for operation in the ISDN network and meet common standards. The resistor is robust and designed for use in connection boxes, enabling a long service life under normal operating conditions.
