"DLP-H45 Set Up External or Line Timing" task on page 16-61
Reference lists define up to three timing references for the node and up to six BITS Out
references. BITS Out references define the timing references used by equipment that can be
attached to the node's Mechanical Interface Cards (MICs). If you attach equipment to the BITS
Out pins, you normally attach it to a node with Line mode because equipment near the external
timing reference can be directly wired to the reference.
