PD 7002:1996 - Essential requirements for connection of terminal equipment to 2-wire analogue interfaces, without capacitive termination, of public switched telecommunication networks using either the earth calling, the loop calling-disconnect clearing, the loop calling-guarded clearing or the loop calling-unguarded clearing signalling method

Here are some key points that might be addressed in PD 7002:1996:
Terminal Equipment Interface: The specification likely defines the essential requirements for the interface between terminal equipment and the 2-wire analog interfaces of public switched telecommunication networks.
Analog Interface Characteristics: It may describe the characteristics of the 2-wire analog interfaces, including the absence of capacitive termination. Capacitive termination is the practice of using capacitors to improve signal transmission and reception, and the absence of it may have implications for signal integrity.
Signaling Methods: The document may provide details on the signaling methods mentioned—earth calling, loop calling-disconnect clearing, loop calling-guarded clearing, and loop calling-unguarded clearing. These signaling methods are likely associated with the establishment, maintenance, and termination of voice or data communication.
Connection Requirements: PD 7002:1996 may specify the requirements for establishing and maintaining connections between terminal equipment and the telecommunication networks using the specified signaling methods.
Compliance and Certification: The specification might include information on compliance with the outlined requirements and possibly recommendations or requirements for certification processes to ensure that terminal equipment meets the specified standards.
Interoperability: Considerations related to interoperability between different terminal equipment and the public switched telecommunication networks may be addressed to ensure seamless communication.
Safety and Regulatory Compliance: The document may include considerations for safety and regulatory compliance to ensure that the terminal equipment and its connection to the telecommunication network meet relevant standards and regulations.
