RAD BE-1 Balun (coax to twisted pair converter)
The BE-1 Balun (coax to twisted pair converter) enables any E1 equipment with coax interface to operate over two twisted pairs (4-wire interface). This miniature, lightweight E1 Balun from RAD provides conversion between a coax interface and twisted pairs for E1 applications ( 2.048 Mbps ). The RAD BE-1 operates without AC or DC power and provides up to 1000V isolation voltage for protection against AC and DC over-voltage on the line. The RAD BE-1 Balun supports ITU G.703 pulse mask on unbalanced and balanced sides. The unbalanced coax E1 interface is 75 Ohm on 2 x BNC (female or male) connectors. The balanced interface is 120 Ohm, RJ-45, 8-pin connector. The RAD BE-1 can also be used to extend ISDN PRI over existing coax cabling. The BE-1 is available from Cutter Networks www.bestdatasource.com .
