What is the conversion rate from STS3c (payload) to T3 (signal)?

The conversion rate is 1 STS3c (payload) equals approximately 3.3605150215 T3 (signal).

Why do STS3c and T3 data rates include overhead?

Both STS3c and T3 signals have framing and overhead bytes that affect the actual usable payload data rate.

Can all equipment directly convert between STS3c and T3 signals?

No, not all equipment supports direct conversion; synchronization and protocol interworking are often necessary.

Key Terminology

STS3c (payload): A concatenated SONET transport signal payload offering a contiguous channel near 155.52 Mbps, used in optical networks.
T3 (signal): A North American T-carrier digital transmission format carrying multiplexed voice and data at 44.736 Mbps through aggregation of 28 DS1/T1 channels.
Framing and Overhead: Additional bytes in transmission signals used for synchronization and control, which reduce the effective payload data rate.
