What does STS48 (signal) represent?

STS48 (signal) is a SONET signal level equivalent to OC-48 providing a synchronous transport rate of 2.48832 Gbit/s, used to carry multiplexed digital payloads over optical fiber.

What is T0 (B8ZS payload)?

T0 (B8ZS payload) is a raw T-carrier bitstream using Bipolar with 8-Zero Substitution encoding, representing time-division multiplexed telephony/data channels as a preserved bitstream.

Why convert STS48 signals to T0 payloads?

Conversion helps break down high-capacity SONET signals into fundamental T-carrier units for transport, testing, or interfacing with legacy telephony equipment that requires B8ZS line coding preservation.
