Key Features BALUN MATE 10/7/2003 #20998 Ordering Information ITEM CODE Choose the complete solution… Balun Mate..................................................................MT243A …or choose the chassis and buy as many modules as you need… Balun Chassis.............................................................RM243A Balun Module..........................................................MT243C-F provide 120-ohm terminations to their customers (in keeping with European ONP requirements). If you need a lot of connec- tions right away, order the Balun Mate (MT243A)—you’ll get the panel plus 16 installed balun modules. Or you can order an empty Balun Chassis (RM243A) and add as many Balun Modules (MT243C-F) as you need for your application. Supporting E1 data rates of up to 2.048 Mbps, the panels bi- directionally match not only signal impedance, but also the pulse shapes of the signals according to the ITU G.703 standard. Also, no AC power or batteries are required. The Balun Mate and Balun Chassis are designed to occupy only 2U in a standard 19-inch (48.3-cm) rack.
