Castelle's FaxPress Premier™ Analog and FaxPress Premier Digital fax servers represent an advanced, state-of-the-art approach to network faxing. Castelle’s patent pending Premier technology, built on existing FaxPress™ hardware and software features, offers a complete, enterprise-level network faxing solution in one robust, server-class machine.

With integrated file storage for system and fax data files, a multitasking embedded Windows operating system and pre-installed FaxPress Premier client and server software, both the FaxPress Premier Analog and FaxPress Premier Digital can support users in various networking environments including Microsoft Windows, Novell NetWare, Linux/Unix, and Apple Macintosh. FaxPress Premier's powerful and flexible software development kit (SDK) also allows users to develop custom fax applications, while the drop directory and drop fax service offer a straightforward approach to production faxing.

The FaxPress Premier Analog and FaxPress Premier Digital fax servers provide unmatched scalability for the growing enterprise. With Intel® Dialogic® 33.6 analog fax modem boards and driver software pre-installed, the FaxPress Premier Analog is available in 4, 8, 12 or 16 line versions.  The FaxPress Premier Digital fax servers support fractional T1, full T1, E1 and ISDN carrier formats.  The FaxPress Premier Digital Fractional T1 and FaxPress Premier Digital T1 support high-speed digital transmission in the North American market, while the FaxPress Premier Digital E1 and FaxPress Premier Digital ISDN support high-speed digital transmission in the European market. 

The FaxPress Premier Digital Fractional T1 supports 8 fax channels across a fractional T1 line, while the FaxPress Premier Digital T1 supports 24 fax channels across a single T1 line. Upgrade packages enable support for up to 72 fax channels across 3 full T1 boards.

Additional FaxPress Premier servers can be added to the network without having to replace existing units, since the FaxPress Premier is easily configured for load sharing, and is also backward compatible with the existing FaxPress server products.

As dedicated network fax servers, the FaxPress Premier Analog and FaxPress Premier Digital provide client workstations with access to incoming and outgoing faxes, phonebooks, transaction logs and other fax-related data via Faxmain®, the Premier client’s fax transmission and server administration utility. FaxPress Premier’s email gateways provide a variety of fax and email integration options, allowing fax messages to be sent and received directly from a number of mail clients. The FaxPress Premier's Secure Web Interface provides a secure, web-based server configuration, administration, and faxing utility that can be used to manage Premier users and administer Premier units, as well as send and receive faxes.  Castelle’s FaxPress Premier fax servers are currently used in government, manufacturing, financial, automotive, hospitality, construction and health care organizations.
