at this time i do have the ext in that field but i've tried with and without neither makes a difference.

also my primary clock source i have set to 020501 which is where my PRI card is, but again i have put no data and it doesn't make a difference the system works the same with are without.

another thing is should i be set to master are slave, once again ive tried both and again makes no difference system works the same either way. so what are the programms for if it dosen't change the way the system acts???
