This setting must match the line encoding of the CSU/DSU at the other
end of the point-to-point link.
7. Click S

Use T1 framing to divide the data stream into 64Kbps channels and to
synchronize with the remote CSU/DSU. This setting must match the
frame format used by the CSU/DSU at the other end of the point-to-point
link.
8. Click the 64
to select the DS0 channel speed for the T1 line.
Some older trunk lines use the least-significant bit of each DS0 channel in
a T1 frame for switching-equipment signaling. T1 frames designed for
data transfer can be set to not use the least-significant bit of each DS0
channel. This setting allows data to be sent over these trunk lines without
corruption but at a reduced throughput. This mode is called the 56Kbps
mode because each DS0 channel now has an effective throughput of
56Kbps instead of 64Kbps. All T1 functions still work in the 56Kbps
mode, including all framing modes and fractional T1 configurations.
