Chapter 5. EP BSC-Attached 3270
The FEP-4600 supports 3270 BSC platforms defined in BTAM applications by means of
a Local Non-SNA to BSC Gateway function. This implementation consists of ESCON or
FICON as the upstream connection, and a serial BSC line on the downstream connection.
For BSC 3270 installations that are currently supported by VTAM on the 37x5, please
refer to the chapter entitled: VTAM BSC-Attached 3270 Platforms
The following illustration shows what the network may look like.
For Non-SNA definitions, the host gen can look very different from one installation to
another, because every attached device requires its own subchannel address and must be
included in the gen. Configuration for the downstream media is performed in the FEP-
4600 configuration. For detailed configuration information, see the FEP-4600 Installation
and Configuration Guide.
