By default, the facility is Admin down. When a cross-connect is provisioned
with a PDH/DSn facility, its Admin status is automatically changed to Admin
Up. When you change a facility from Admin Up to the Admin Down state, the
following occurs:
• STM facility
— traffic will not be carried on the port
— Tx laser is shut off
— alarms present on the port are cleared
— alarm conditions are not declared
— performance monitoring is terminated
— DCC will be disabled
• E1/E3/DS1/DS3 facility
— traffic will not be carried on the port
— alarms present on the port are cleared
— alarm conditions are not declared
— performance monitoring is terminated
• 10/100BT Ethernet facility
— traffic will not be carried on the port
— Client Signal Fail will be sent on the WAN facility
— alarms present on the port are cleared
— alarm conditions are not declared
— performance monitoring is terminated
• Gigabit Ethernet facility
— traffic will not be carried on the port
— Tx laser is shut off
— Client Signal Fail will be sent on the WAN facility
— alarms present on the port are cleared
— alarm conditions are not declared
— performance monitoring is terminated
Note: The WAN state follows the state of the associated 10/100BT
Ethernet or Gigabit Ethernet port. If a 10/100BT Ethernet or Gigabit
Ethernet facility is placed in admin down state, the corresponding WAN
state will automatically be placed to admin down.
