Selecting a LAN interface protocol
This section provides details about how to select a remote interface protocol to connect to the Series
3700A. The Series 3700A provides three LAN interfaces with three associated LAN protocols (each
interface uses a different protocol). Select the interface based on the protocol needed. The dead
socket termination interface (DST) is provided to solve connection problems; it is not a protocol
