This chapter focuses on connecting two pods via a T1 connection as well as a serial port connection. T1 connectivity simulates connectivity between two different companies. A serial connection is more indicative of connectivity between two sites of the same company. Lab 7-2 introduces the idea of class of restriction (COR).
