BE-1 Coax to Twisted Pair Converter for E1
BE-1 Coax to Twisted Pair Converter for E1
The BE-1/F and BE-1/M Balun (coax to twisted pair converter) from RAD enables any E1 equipment with coax interface to operate over two twisted pairs (4-wire interface), as shown in Figure 1.
Two BE-1 units back-to-back allow 4-wire ISDN equipment to operate over existing coax cables.
BE-1 is insensitive to the direction of the signal, allowing transmit and receive lines to be reversed without affecting operation.
BE-1/F and BE-1/M are a miniature, lightweight Balun. It operates without AC or DC power and provides up to 1000V
isolation voltage for protection against AC and DC overvoltage on the line.
