ACTUAL SEQUENCE MODULUS

         Sequence number modulus in use on the link. Until negotiation is
         complete, this attribute has the value 128. However, if the value of
         the characteristic sequence modulus is 8, the modulus always appears
   	as the value 8.

     INTERFRAME DELAY

         Time required between frames to enable the local station to
 	successfully receive them.

     LINE TYPE

         Defines whether the underlying physical line is switched or
 	nonswitched.  This status affects the subset of port states that are
 	related to a given link.

     MAXIMUM PDU SIZE

         Maximum frame size in octets that can be used on the link. Until
 	negotiation is complete, the value of this status attribute is the
         same as the characteristic preferred maximum data size.

     NEGOTIATED CRC TYPE

         CRC mode that has been negotiated with the remote station. This mode
 	will not be used until the station is next enabled.  Until
         negotiation
 	is complete, the value of this is 16-bit.

     PHYSICAL PORT

         Name of the port in the Physical layer associated with the
 	communications link.

     RESPONSE ADDRESS

         Address that the remote station puts in response frames.

     STATE

         State of the HDLC link. This reflects the last enable or disable
 	command issued.

         OFF - The link is disabled.

         ON -  The link is enabled.

     WINDOW SIZE

         Maximum number of I-frames that can be outstanding before an
 	acknowledgment must be received. Until negotiation is complete, the
 	value of this status attribute is the same as the characteristic
 	preferred window size.
