Four versions of PESIT have been defined,
allowing it to operate in the following environments :
- over an X25, X32 or PAD network layer (PeSIT.F')
- over an ISO Session layer above a public network (PeSIT.F)
- over an ISO Session layer above an Ethernet 802.3
LAN (PeSIT.F"')
- over an hyperchannel LAN (PeSIT.F")
In each case, the protocol is identical; only the
interface with the lower layers is different.
This interface is defined in the PESIT technical
specifications.
