This attribute specifies the maximum number of Data Direct SVCs
which this LEC can have active at any one time. When operating at
the maximum, an SVC setup request releases the oldest 10% of the
Data Direct SVCs of this LEC.
A SET alarm is issued when currDataSvcs rises above 95% of this
value and is CLEAR-ed when it falls below 85%.
Set maxDataSvcs as low as acceptable since a fixed amount of
memory is consumed proportional to this value on every LP with
this feature present.
