HI,

If your router physically has BNC connectors and is G.703 only, then you will need a G.703/E1 (75 Ohm/ 120 Ohm balun) impedance matcher! You can buy these from the likes of Black Box.

But, if you are using the VWIC-1MFT-E1 modules in your routers there is a command line to get around it. Go to the controller context in config mode and change the impedance using the "line-termination" command to what you want. If this is what you do, then all you will need to a PRI cross-over cable (1&2 to 4&5, and vica versa)
