                            The FEP-4600 is a powerful,   cost effective solution capable of replacing many of the traditional 3745/46 FEP   features. It eliminates costly NCP/SSP or EP software licenses, and provides   SNA, Non-SNA, and IP support to communicate with a variety of remote devices. In   addition, both cross-domain (PU4/SNI) communications and BiSync protocol   conversion are provided.

                         IBM 3745/3746 FET 已經停產很久了,目前維護成本很高,Visara 提供解決方案由FET4600 或者 Visara 1174-25S取代。  
                              Windows TN3270 Server不穩定、需要每天upgrade及資料備份,還有軟體License費用,須要加強人工照顧及維修費時等問題,很麻煩。Cisco CIP 價位超高,每增加Session又要License費用,真是無底洞。Visara 1174-25S 硬體升級空間大、可靠性高、維修快速、不須要資料備份、沒有TN3270  軟體License費用、節省人力及價格適中等優點。  
                              上傳方式提供ESCON光纖 或Parallel BUS & TAG與主機連接,下傳方式Ethernet、Token Ring 、 Coax三種選擇方式連接至TN3270 PC 、 Coax Terminal 、 Thin Client,提供32 up to 128個Coax Session、提供1024 up to 4048個 Ethernet  Session、。
