Description
• 10/100Base-T connectivity between the local craft PC and the
OME6130.
• Central office LAN provides switched 10/100Base-T
connectivity between the carrier's DCN and the OME6130.
• Two external synchronization inputs for timing generation
references which enable the OME6130 to be timed from an
external timing reference of G.813 Option 1 or better quality.
Both clock and data formats are supported.
• External synchronization outputs for timing distribution
references which enable other network elements to be timed
from the OME6130.
• Alarm output port enables the customer to monitor the shelf
level alarms (Critical, Major and minor) onto external equipment,
such as lights or sirens.
• These contacts are normally open.
• Seven telemetry inputs enable the customer to connect external
environmental monitoring equipment to the OME6130 (for
example, door open indicator, fire alarm, and flood alarm).
• The alarm inputs are operating as follows:
open circuit = no alarm
closed circuit = alarm
• Remote dial-in access through modem to the OME6130.
• F1 user byte access (for clear channel access)
