I have a customer that will have a Modular ICS in each of two adjacent buildings. We can run cable between the two locations. What are the options to connect the two MICS units? I know about using T1/PRI to connect through the T1 provider, but I'm looking for a simple less expensive solution to connect via a cable connection without using T1 cards. Ideally they'd like to be able to dial station to station between the buildings. I've heard you can connect two MICS units via an ATA II on each system with limited functionality, but don't know how that would work. Any help?
