isdnutils-xtools 1:3.10.20070306-0ubuntu2 (i386 binary) in ubuntu gutsy

 These are the graphical utilities for ISDN, xmonisdn and xisdnload.
 They provide, each in their own way, a visual indication of the status of
 the ISDN lines, so that it is directly obvious when there is a connection,
 for example.
 .
 This has been separated out of the main isdnutils package so that if you
 don't run X but do need ISDN, you don't have to include the X libraries
 unnecessarily.
