Chapter 6. Support of PU 4 Connections
The FEP-4600 supports PU 4 platforms by means of a PU 4 Gateway function. These PU
4 platforms include a 3745 or another platform that is emulating a 3745 such as IBM’s
CCL product, another FEP-4600, an Integrated Communications Adapter (on some
mainframes), or a router passing PU 4 traffic. It can also support another Visara FEP-
4600 operating in a PU 4 gateway mode. Both same SNA network and different SNA
network (SNI) connections are supported over any of the specified interfaces. Following
is a summary of connection types that are supported on the FEP-4600:
 SDLC connection to a remote 3745
 Token Ring (LLC) connection to a remote 3745 direct or using a DLSw router
 Ethernet (LLC) connection to a remote 3745 direct or using a DLSw router
 ESCON Channel-to-Channel connection either direct or through a clustered (FEP-
4600 to FEP-4600) connection
 Ethernet (IP) connection to a remote FEP-4600
A variety of implementation scenarios are described below.
