Hi Groupdstudy, I have a number of sites running ISDN PRI E1. But some of our Channelize E1 card is balance and some of them is unbalance. Can someone highlight to me what is the differece between them? Most of our ISDN switch type is primiary-net5. Can I use balance/unbalance on this switch?.. Thanx a million.... _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
