Step 4 Connect one end of each asynchronous/synchronous cable to the asynchronous/synchronous ports
(labeled Serial n (A/S)), and then connect the other end to a CSU/DSU or asynchronous device. (See
Figure 3-14.)
For asynchronous/synchronous port pinouts, refer to the appendix "Cable Specifications."

Step 5 Connect the ISDN BRI port (RJ-45) to an NT1 device. (See Figure 3-15)
