SONET Advantages
The big advantage of SONET is that it was designed to provide the following functions needed in
networking at that time:
Single-step multiplexing
Access to low-level signals directly

Synchronous timing to eliminate bit stuffing
Overhead room for acceptable network management information
Allow transmission of data at higher speeds (50 Mbps+)
