Notebook modems communicate with analog signals. Currently, many newer telecommunication installations in hotels and offices use digital signals. These conflicting circumstances create two problems. First, your modem may simply refuse to work with a digital phone signal. Second, the higher power of digital signals may damage or destroy your modem. We offer several products to safeguard your modem and on-line communications from damage or interruption. Our modem saver products provide you with a range of options - from basic over-current and polarity testing to surge protection and line filtering - now available in the same component!
