Dear All,

I have bought a digium TE205p in order to move our E1 pri from a siemens pbx to an asterisk server platform, I have already gathered the data needed to configure the card but I am troubled by one thing that seems unclear on all the documents I read.

The E1 is currently inserted in a modem and from the modem goes out a cable to the siemens pbx so should I take the E1 from that modem or take the E1 directly from the provider, plus is there any special pin assignment.

Your Help will be very much appreciated.

If you really mean to say modem then what you are doing will not work. Maybe you mean a CSU/DSU? If it is a CSU/DSU or "the box that the telco owns, take the cable coming out of it. Plug it into your asterisk box and see if you get a green light. I suspect you will since it is working with your Siemens box. If not, make an E1/T1 crossover cable. Pinout is:
1 -> 4
2 -> 5

Thanks,
Steve Totaro

Thanks,
Steve
