ATM/SONET/SDH Circuits

ATM (Asynchronous Transfer Mode), SONET (Synchronous Optical Network), and SDH (Synchronous Digital Hierarchy) circuits are high-speed communication technologies used in telecommunications networks.

ATM is a cell-based network technology that enables high-speed data transfer, video and voice communication. It divides data into fixed-size cells and sends them across the network using time-division multiplexing (TDM).

SONET and SDH are both standard protocols for optical telecommunications transport. They use synchronous timing signals to enable high-speed communication over fiber optic networks. SONET is used primarily in North America, while SDH is used primarily in Europe and other regions.

ATM, SONET, and SDH circuits offer several advantages over other communication technologies. They provide high-speed communication with low latency, allowing for efficient data transfer and real-time voice and video communication. They also provide a high level of reliability and fault tolerance, making them ideal for use in mission-critical applications such as banking, healthcare, and defense.

However, these circuits also require specialized hardware and software, and can be more expensive to implement and maintain than other communication technologies. They also require a high level of expertise to configure and manage.
