FLEXIBLE CONNECTIVITY

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.
