Step 8 Check the Interface Configuration Mode field. This field indicates the clock configuration and the
administrative status of the interface.
Step 9 Check Sonet Overhead fields. These fields indicate the following:
• k1/k2—used for Automatic Protection Switching (APS)
• s1s0—(2 bits) not used by SONET, may need to be configured for SDH
