As an in-kernel STREAMS module supporting the AT&T defined Transport Provider Interface (TPI) at the top and the DLP/LLI (for Ethernet LAN access) and NPI (for RFC 1006) interfaces at the bottom. It also works with both XTI and TLI.

On Ethernet LAN, support is provided for:

transport class 4 including the ISO Connectionless Network Protocol (CLNP)
the ES-IS routing protocol
configurable LSAPs as permitted by the underlying Link Level
RFC 1006. Allows OSI communication over a TCP/IP network
the Fujitsu facility of transport switching, as required by Fujitsu’s multi-processor systems
the facilities required by TOP NetBIOS for use with LAN manager (e.g. loop-back, multi-cast, multiple local NSAPs, transport datagrams).
