Zoom Telephonics: Zoom ADSL Modem, PCI Model 5505 The Zoom ADSL Modem PCI Model 5505 is an Asymmetric Digital Subscriber Line (ADSL) data modem that delivers up to 8 Mbps data transport over existing copper wire lines. The Zoom ADSL Modem supports several ADSL protocols. An adaptive data rate capability can automatically set transmission speed using algorithms that detect the signal quality of the telephone line. The variable data rate and line code capability supports a broad range of infrastructure conditions, including loops with bridge taps, significant crosstalk, and AM radio interference. Downstream and upstream data rates can also be fixed with a manual mode. The Zoom ADSL Modem PCI is designed for easy installation in a Windows 98 or Windows 2000 computer's PCI slot. The Zoom ADSL Modem is capable of transmission of ADSL without disturbing phone service on the same telephone line. Additionally, the Zoom ADSL Modem PCI is software upgradeable to support service and performance enhancements. Up to 8 Mbps Internet / data access across existing copper phone lines Easy, fast Windows (R) installation and configuration; plugs into PCI slot Needs no external voice/ data splitter in G.Lite mode Supports up to 8 simultaneous ATM virtual connections Software upgradeable Traditional Zoom quality and value The ADSL protocols supported include ANSI T1.413 issue 2, G.DMT (ITU G992.1), G.Lite (ITU G992.2).
