Connecting the BITS Filter Module and Clock Contacts (Optional)

The Cisco 10000 series router supports a Building Integrated Timing Source (BITS) Filter module. This

module is already installed in a new chassis that is configured with a PRE4. If you are upgrading a Cisco

10000 series router with a PRE4, you can install the Building Integrated Timing Source (BITS) Filter

module on the backplane of the chassis. This module is only required if you are connecting a BITS clock to

the chassis.

The BITS Filter module (ESR-BITS-FLTR) allows you to attach BITS lines to the router using wire-wrap

posts. It has a filter that prevents conducted emissions from the chassis traveling down the BITS lines and

isolates the system from voltage surges.

The BITS Filter module has wire wrap posts to connect two sets of twisted pair (shielded or unshielded)

receive TIP and RING lines from an external source to the system. The pins are associated with specific

PRE slots.
