Step 5
In the Reference Lists area, you can change the following information:
Note
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 BITS Out pins on the backplane. If you attach equipment to 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.
•
NE Reference
•
BITS 1 Out
•
BITS 2 Out
