DS-3 is the third level in the PDH multiplex hierarchy found in North America. DS-3 has a
bandwidth of 44.736 Mbit/s and carries seven DS-2 channels of 6.312 Mbit/s, these in turn
carry four DS-1 signals of 1.544 Mbit/s.
There are currently four different ways to transmit ATM cells over DS-3. They are:
•
C-bit parity ADM
•
C-bit parity PLCP
•
M23 ADM
•
M23 PLCP
