+Input from Michael Buenter, Jan Ceuleers, Chris Lueders, and others. Thanks!

+The proposed new information text in nodelist trailer is as follows:
+
+   Nodelist  Specification of minimal support required for this flag;
+   flag      any additional support to be arranged via agreement between users
+   ========  =================================================================
+   V110L     ITU-T V.110 19k2 async ('low').
+   V110H     ITU-T V.110 38k4 async ('high').
+   V120L     ITU-T V.120 56k async, layer 2 framesize 259, window 7, modulo 8.
+   V120H     ITU-T V.120 64k async, layer 2 framesize 259, window 7, modulo 8.
+   X75       ITU-T X.75 SLP (single link procedure) with 64kbit/s B channel;
+               layer 2 max.framesize 2048, window 2, non-ext.mode (modulo 8);
+               layer 3 transparent (no packet layer).
+   ISDN      Other configurations. Use *only* if none of the above fits.
+   ===========================================================================
+   NOTE: No flag implies another. Each capability MUST be specifically listed.
+   If no modem connects are support, the nodelist speed field should be 300.
+
+   Conversion from old to new ISDN capability flags:
+   - Nodes in the USA currently use the 'ISDN' flag.
+     Most will be able to change to V120H (64k lines).
+     Also many to V120L,V120H (64k lines) with autodetecting equipment.
+     Some to only V120L (still with 56k lines).
+   - Nodes in Europe currently use the ISDNA, ISDNB and ISDNC flags.
+     A simple translation will do the trick here.
+     ISDNA -> V110L
+     ISDNB -> V110H
+     ISDNC -> X75
