DH+

ll.rrr.ss

lllocal bridge address

or

ll.rss

lllocal bridge address

rsscombined remote bridge address and
remote station address

The address ll.rss is an offlink address shortened by
combining the remote bridge and remote station addresses
into one three–digit number. The system reads only the first
digit of the remote bridge address, and adds the two–digit
remote station address to produce a shorter address that still
points to the same node.
