What does T1C (signal) represent?

T1C (signal) is a North American digital carrier signal transmitting 1.544 Mbps by time-division multiplexing 24 voice/data channels typically used on leased or trunk lines.

What is STM-4 (signal) used for?

STM-4 (signal) is a standardized optical transmission frame used in SDH networks with a nominal rate of 622.08 Mbps, mainly for regional or inter-city backbone links aggregating various digital traffic.

Can I physically convert T1C signals to STM-4 with this tool?

No, this tool provides a logical conversion of capacity values. Actual physical conversion requires multiplexing hardware to aggregate multiple T1C signals into an STM-4 frame.
