What is the main difference between STS3c (signal) and STS3c (payload)?

STS3c (signal) represents the gross transport rate in SONET, while STS3c (payload) indicates the usable contiguous payload after accounting for framing and overhead.

Why is the conversion from STS3c (signal) to STS3c (payload) important?

It enables precise bandwidth allocation and network planning by reflecting the actual payload capacity available for high-bandwidth client signals.

Can I use this conversion for non-SONET data rates?

No, this conversion is specific to SONET concatenated signals and payloads and does not apply to non-SONET interfaces.

Key Terminology

STS3c (signal): A SONET electrical transport signal representing a contiguous payload formed by concatenating three STS-1 channels, with a gross data rate of 155.52 Mbit/s.
STS3c (payload): The concatenated SONET payload container providing a single contiguous transport channel at 155.52 Mbps, reflecting usable bandwidth after framing and overhead are considered.
SONET Framing Overhead: Protocol-specific bytes and structures in SONET responsible for managing signal transmission but reducing the actual payload capacity.
