The table below describes types of link that the Rumba Router supports.
| Link Type | Function |
|---|---|
| APPN | Connects to an AS/400 host by using an existing network connection as a node. For example, an APPN connection between your PC and an AS/400 host can be used to access another AS/400 host that does not have a direct physical connection to your PC. |
| MPTN (SNA over TCP/IP) | Connects to an AS/400 host using SNA or APPC to communicate over TCP/IP networks. The full capability of the Rumba APPC engine is used over an existing TCP/IP backbone, linking client workstations to the host and providing transparent access to functions such as AS/400 printing and file transfer. |
