We are talking to a customer who has 2 sites, Magix 1.5 in one and Magix 2.0 in the second - they are networked with a point to point T1 that i believe is being used for both voice and data between the sites (cisco 11720's at each site). Each system has 3 or 4 analog lines into 412 TDL cards and i am assuming that they are getting additional circuits off a second T1 at one of the sites. I am trying to figure out how that is configured and was hoping to get some insight as to what i need to look for to determin exactly how they are configured. I know this description is somewhat limited so please tell me what other info i need to provide to help you guys answer my questions. Ultimate goal is to remove Magix and go to IP system due to some functionality issues but i need to know how they are configured before i quote the upgrade. Thanks!
