for the DDS CSU/DSU. The network configuration is automatically set when
the DTE Rate is set. For example, 56 Kbps DTE Rate sets the network to
DDS I and 64 Kbps DTE Rate sets the network to DDS II CC 64K.

The unit can operate at 56 or 64 kbps.
DTE Clock
The polarity of the clock is either normal or inverted.
