BITS Port
The Building Integrated Timing Supply (BITS) port is an RJ-45 interface that provides external
synchronized clocking through a timing signal generator (TSG). The BITS input is an external timing
reference that must be traceable to a stratum 3 clock or better. The BITS port on the switch can be
configured to accept either a T1 or an E1 framed input. Although this clock input is T1 or E1 framed, it
does not carry data and cannot be used for any other purpose than to derive clocking for the system.

Alarm Input Port

The switch supports four alarm inputs. The alarm input is a dry-contact alarm port. Use the CLI to define
each alarm input to respond to a normally open or closed dry-contact closure and to define the alarm
severity as minor, major, or critical. When a condition triggers an alarm, the console displays an alarm
message, and the corresponding Alarm LED responds (see the
