What is a T3 (signal)?

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

What does Virtual Tributary 1 (payload) represent?

Virtual Tributary 1 (payload) is a sub-rate container within SONET/SDH frames used to carry lower-bit-rate signals multiplexed into a higher-rate optical stream, standardizing slots for signals such as DS1/T1.

Why convert T3 signals to Virtual Tributary 1 payloads?

Users convert T3 signals to VT1 payloads to map high-capacity channels into multiple lower-rate containers for efficient transport, switching, and bandwidth management over SONET/SDH networks.
