The force DTE acknowledge setting. This object is only applicable to
HDLC interfaces directly over a high speed serial interface (HSSI).
This is set to force Cisco compatibility mode, and is only valid when
the lower interface is configured for internal (DTE) clocking.
At creation, if a value for this object is not specified, a default will
be chosen that is suitable for the type of lower interface on which this
interface is stacked. If the lower interface is not HSSI, then the
default value will be forceDteAckUnsupported(0); if the lower
interface is HSSI then the default value will be
forceDteAckNormal(1).
