G703

Hi,

 

We have a customer in Mexico who just ordered a new digital E1 PRI.

The only problem is that Telmex (the local telco) hands out these with a G703 interface consisting of 2 coaxial cables out of a Watson sdhl modem.

 

Anybody knows or has experience on how to interface and connect this to a regular sangoma t1/e1 card? We have a balun that goes from the g703 coaxial 75ohms to a rj45 120ohms. Is that enough? what about the rj45 cable then that goes from the balun to the sangoma? should it be a regular ethernet? e1 cable??

 

Any help and ideas are most welcomed.

 

Thanks!

Nathan
