SONET Payloads
1
Table A-1 shows the digital signals that can be transported as SONET payloads.
DS1 and DS3 signals are the most important of these signals in the current
network. Broadband payloads, such as asynchronous transfer mode (ATM) and
fiber distributed data interface (FDDI), with rates of 150 Mb/s and higher, are also
important. Other payloads may be defined for specific applications.
