What is a T1 (signal)?

T1 (signal) is a North American digital transmission standard that carries data at 1.544 Mbps by multiplexing 24 DS0 channels of 64 kbps each plus framing over copper or similar media.

What does STS1 (signal) represent?

STS1 (signal) is the basic SONET electrical/frame unit, operating at 51.84 Mbps including overhead, and forms the optical carrier OC-1 for synchronous optical networks.

Why convert from T1 to STS1 signals?

Converting from T1 to STS1 helps relate lower bandwidth North American digital circuits to higher capacity SONET transport systems, enabling integration and multiplexing into modern optical networks.
