What is the difference between STS3 and STS3c signals?

STS3 represents a standard SONET signal with multiple payloads, while STS3c is a concatenated signal that forms a single contiguous payload for high-bandwidth streams.

Does converting from STS3 to STS3c change the data rate?

No, the conversion does not alter the data rate; both have an identical throughput of 155.52 Mbps.

Why would I use STS3c instead of STS3?

STS3c is used to carry high-bandwidth streams as a single channel without byte-interleaving, facilitating efficient transport of Ethernet or packet data over SONET.

Can all network equipment handle STS3c signals?

No, some systems do not support concatenated payloads, so compatibility must be confirmed before using STS3c.

Key Terminology

STS3 (signal): A SONET digital transmission signal with a line rate of 155.52 Mbps composed of three STS-1 channels used for multiplexing multiple low-rate channels.
STS3c (signal): A concatenated SONET signal representing a single contiguous payload with a gross data rate of 155.52 Mbps, designed to carry high-bandwidth streams without byte-interleaving.
SONET: Synchronous Optical Networking, a standard for digital transmission over optical fiber.
