Our modems are extremely flexible and powerful, and incorporate a large number of optional features that can be purchased at the initial order or while in the field. The FAST technology facilitates on-location upgrade of the operating feature set without removing a modem from the setup. With FAST technology, users have maximum flexibility for enabling functions as they are required. FAST allows a user to order a modem precisely tailored for the initial application. When service requirements change, the operator can upgrade the topology of the modem to meet those requirements within minutes. FAST permits the purchase and installation of options through special authorization codes loaded into the unit either via the front panel keypad or entered remotely via the remote port located on the modem rear panel. This accelerated upgrade can be accomplished because of FAST’s extensive use of the programmable logic devices incorporated into our products.
