E1 in South America

[MB501334048]

Have an E1 in South America, carrier is presenting Coax pair - which is a slight problem in itself, but am having a hard time verifying if the E1 is 75 Ohms or 120 Ohms. Cisco used to make the cable CAB-E1-RJ45TWIN (75Ohm) or CAB-E1-TWINAX-3M (120Ohm) Anyone have an idea on the standard setups for South America?

Most E1's I have seen in most of south america are 75ohm coax or 120 ohm rj48 (twisted pair)

I'm not sure anyone delivers 120 ohm over coax anymore but you never know.

If the coax is a issue many of the providers will put in a balun to convert it to 120ohm twisted pair. There are many vendors that sell these even cisco does CAB-ADPT-75-120
