We are currectly configured with USR Total Control chassis and we have both
Modems and ISDN shared on the ports... we have configured our 2 PRIs with 47 B
Channels which support 47 Analog and Digital at the same time. We are
extremely pleased with the simplicity of the Install. With the most recent
Codes, the chassis is a plug in and forget system...
