ANF10 is spoken by the DN87 on a DL10 or a DN87S on the PDP11 
front end. Standard was DQ11 on the DN87. 
I can talk async DDCP on a DH line.
2020 uses a DUP/KMC combination to talk ANF 10.
And RDH did a Ethrnet driver for the NI.
With the DDP hack you can use a DDCMP device on the 
frontend to talk DEcnet4 or IP to a VAXen with BSD unix.

  Yes, ANF10 also uses Ddcmp.
 On simh Anf10 also uses the Dmr/Dmc implementations.
