What does STS12 (signal) represent in networking?

STS12 (signal) is a SONET transport signal with a line rate of 622.08 Mbit/s that carries multiplexed digital payloads plus overhead for network management.

What is the significance of STS1 (payload) in SONET?

STS1 (payload) refers to the user-data capacity within an STS1 frame, specifically the usable synchronous payload envelope at 50.112 Mbps.

Why convert from STS12 (signal) to STS1 (payload)?

Converting helps determine how many STS1 user payloads fit into an STS12 signal, enabling accurate bandwidth allocation and service provisioning.
