Highlights
Compact, 30 GSM terminals (90 SIMs per E1) in a 19-inch chassis.
GSM is integrated to the E1 PRI ISDN (Euro ISDN) Interface.
Exceptional voice quality. The two wire trans-hybrid analog path (present in the Fixed Wireless Terminals) is eliminated in the innovative design, resulting in improved voice quality, clearer voice and superior channel separation by reducing the susceptibility to echoes that result from the analog two wire trans-hybrid VF paths.
