Any system with NS transport has TCP/IP available in the form of
NetIPC intrinsics. This goes back to before MPE iX. For a long
time, the transport was actually bundled with the hardware. Network
Services, however, is a different story; NS Services include
DSCOPY (NFT or Network File Transfer), RFA (remote file access),
VT (virtual terminal), and a few others.
