 /* 
  * The purpose of the SDT interface is to provide a separation between
  * the SL (Signalling Link) interface which provides SS7 Level 2 (LINK)
  * state machine services and the underlying driver which provides
  * essentially HDLC capablities.  In SS7 the entity providing HDLC
  * services is called the Signalling Data Terminal (SDT).  An SDTI
  * implements the AERM/SUERM/EIM and DAEDR/DAEDT capabilities and
  * communicates upstream to the Signalling Link using the primitives
  * provided here.
  *
  * The SDT interface also recognizes Local Management Interface (LMI)
  * primitives defined elsewhere <sys/ss7/lmi.h>.
