Because mixed timing can cause timing loops, Cisco does not recommend using the Mixed
Timing option. Use this mode with care.
"DLP-B69 Set Up External or Line Timing" task on page 3-17
The BITS Facilities section sets the parameters for your BITS1 and BITS2 timing references.
Many of these settings are determined by the timing source manufacturer. If equipment is timed
through BITS Out, you can set timing parameters to meet the requirements of the equipment.
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. If you attach equipment to the MIC 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.
If the changes do not appear, repeat the task. Refer to the Cisco ONS 15327 Troubleshooting
Guide, as needed.
