Synchronization Cable
The synchronization cable is connected to the SYNC port on the faceplate of
the 3930 system. This port is used for the BITS interface, 1PPS or Time of Day
and has an RJ-45 jack.
Note: The BITS interface can be configured to be either BITS-IN or BITS-
OUT. It cannot do both BITS-IN and BITS-OUT simultaneously.
Ciena offers two optional cables for this interface that are 6 foot long shielded
cables with the following specifications:
• 100 Ohm cable with RJ-45 connectors is cable 170-0083-900
• 120 Ohm cable with RJ-45 connectors is cable 170-0084-900
One end has a shielded RJ-45 connector and the other end is un-terminated.
When using this cable, the shield of the un-terminated end must be
connected.
A customer supplied cable can also be used provided it is shielded, the cable
is CAT 5 or better and the shield is terminated at both ends. This interface is
classified as intra-building only.
See “Installing a Sync Cable (Optional)” on page 2-25 for a procedure.
