Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such cases, a notice will be given in the installation instructions.

Do not attempt to tamper with any carrier-provided equipment or connection hardware.

Electromagnetic Compatibility (EMC)

The equipment is designed and approved to comply with the electromagnetic regulations of major regulatory bodies. The following instructions may enhance the performance of the equipment and will provide better protection against excessive emission and better immunity against disturbances.

A good earth connection is essential. When installing the equipment in a rack, make sure to remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an external grounding lug is provided, connect it to the earth bus using braided wire as short as possible.

The equipment is designed to comply with EMC requirements when connecting it with unshielded twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on certain cables. In such cases, special instructions are provided in the manual.

Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.

The compliance of the equipment with the regulations for conducted emission on the data lines is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss (LCL).

Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary protection against surges on the data lines. Primary protectors should be provided in the building installation.

The equipment is designed to provide adequate protection against electro-static discharge (ESD). However, it is good working practice to use caution when connecting cables terminated with plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist strap.

FCC-15 User Information

This equipment has been tested and found to comply with the limits of the Class A digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the Installation and Operation manual, may cause harmful interference to the radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

T1, E1 specifications

RAD Data Communication specializes in providing advanced networking solutions, particularly for E1 and T1 lines. These digital transmission systems are pivotal in telecommunications, allowing for efficient data transfer, voice communication, and multimedia services.

E1 and T1 lines are standardized digital circuits offering capacity for multiple channels. A T1 line, commonly used in North America, accommodates data transmission at a rate of 1.544 Mbps, while an E1 line, predominantly used in Europe and other parts of the world, supports a rate of 2.048 Mbps. Each line can carry multiple voice channels—up to 24 for T1 and 32 for E1—making them suitable for both voice and data services.

One of the main features of RAD's E1 and T1 solutions is their versatility. These lines can be utilized in various applications, including traditional telephony, private branch exchanges (PBXs), and modern Voice over IP (VoIP) networks. RAD's solutions enable users to seamlessly migrate from older systems to more integrated and efficient digital networks without sacrificing performance.

RAD Data Communication focuses on ensuring reliability and robustness in their E1 and T1 offerings. With built-in error detection mechanisms, such as cyclic redundancy check (CRC), these systems maintain high levels of data integrity. In addition, RAD’s devices often incorporate advanced features like Adaptive Rate Control, allowing for dynamic adjustments to accommodate varying network conditions.

Technology-wise, RAD integrates advanced protocols and features, such as Frame Relay and Multiprotocol Label Switching (MPLS), into their E1 and T1 equipment. This flexibility supports the transmission of diverse data types, ensuring users can transition smoothly between legacy systems and modern technologies.

Another characteristic that sets RAD's products apart is their management capabilities. Many devices come equipped with SNMP (Simple Network Management Protocol) support, enabling remote monitoring and management. This feature is essential for network administrators seeking to maintain optimal performance and quickly address potential issues.

Moreover, RAD's E1 and T1 solutions are designed for easy integration into existing network infrastructures. Their compact and modular design allows for straightforward installation and scalability, accommodating future growth and technology advancements without major overhauls.

In summary, RAD Data Communication’s E1 and T1 solutions are characterized by their reliability, versatility, and advanced management features. Designed to meet the evolving needs of communication networks, they ensure that users can take full advantage of both traditional and modern telecommunications technologies.
