What does T3 (signal) represent?

T3 (signal), also known as DS3, is a North American digital transmission format that carries multiplexed voice and data at 44.736 megabits per second through time-division multiplexing of 28 DS1/T1 channels plus framing overhead.

What is the significance of STS3 (payload)?

STS3 (payload) indicates the user-data portion of an STS-3 frame used in SONET synchronous transport, representing the bytes available for client traffic after subtracting SONET framing and overhead bytes.

Why convert from T3 (signal) to STS3 (payload)?

This conversion helps in accurately determining usable user data capacity within an STS3 frame from a known T3 signal rate, which is essential for evaluating transmission efficiency and resource allocation in telecommunications.
