The following illustration shows an RJ-48C to BNC apir splitter cable (P/N 83229):
Some countries require different adapter cables. Dialogic offers a BNC splitter cable with the shield connected to transmit and receive outer conductors:
Note: This cable does not convert impedance. To connect a CG board with RJ-48C interfaces to a 75-ohm connection, you must either use this cable and configure the board as G703_75_OHM, or use an external balun and configure the board for 120-ohm operation.
