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
