What does STS3c (payload) represent in data transfer?

STS3c (payload) is a SONET payload container with a line rate of 155.52 Mbps used to carry high-bandwidth client signals across optical transport networks.

Why convert STS3c (payload) to OC1 units?

Converting to OC1 helps understand how many base optical carrier signals correspond to the higher-bandwidth container for bandwidth allocation and network planning.

Can the conversion rate vary in real usage?

While the formula is fixed, actual payload capacity can differ slightly due to overhead and synchronization in practical network implementations.
