What does STS3c (payload) represent?

STS3c (payload) is a SONET payload container that provides a contiguous transport channel with a gross line rate of 155.52 Mbps, commonly used to carry high-bandwidth client signals like Ethernet or IP circuits.

What is STS48 (signal) used for?

STS48 (signal) is a high-capacity SONET signal with a transport rate of about 2.48832 Gbit/s, used to carry multiplexed digital payloads over optical fiber in telecom networks.

Why is there a conversion rate between STS3c and STS48?

The conversion helps to understand how multiple lower-rate STS3c payloads aggregate into a higher-speed STS48 signal for effective network grooming and bandwidth management.
