A multistation access unit (MSAU) is a central device/hub used in computer networking to connect network nodes or computer or devices with local area networks. MSAU provides a means of data-sharing between different computing devices in an organization.
The working mechanism of MSAU is based on token-ring network topology in which all computers and computing devices are connected with each other in a logical circle. In this system, connectivity with other computers remains stable and users continue to communicate with each other when one computer or computing device fails.
Also known as a media access unit (MAU), which is often called an Ethernet transceiver.
Techopedia Explains Multistation Access Unit
A multistation access unit is a standalone device or connector that is used to connect devices attached to a network over a token-ring network. Each MSAU includes eight ports.
There are two types of MSAU:
Active MSAU
It does not provide any kind of power to the network or to signals.
It is powered and is used to regenerate or boost network traffic signals.
An MSAU has the following characteristics:
Fault Tolerance -An MSAU provides fault tolerance in an established network. This can prevent many network device failures.
Traffic Bypass-If any computer goes down, the MSAU bypasses the network traffic to provide uninterrupted communication between network nodes.
