Testing Trunks
If you find a central office trunk that does not have dial tone, check
! 
for a bad adapter or loose connection.
If adapters and wiring are in working order but you still do not hear a dial
tone, notify the Lucent Technologies Service Center acting as the
customer's agent.
When you hear a dial tone, dial a known telephone number to verify
! 
dialing.
After the central office completes the connection, check that you have
good two-way transmission.
If you cannot dial out on any of the trunks, notify the Lucent
! 
Technologies Service Center acting as the customer's agent.
It is the customer's responsibility (or that of the customer's agent) to
report service outages to the local telephone company.
Testing Ground-Start Trunks
To perform this test, you need a single-line telephone with a ground key or a
ground-start button.
NOTE:
If a single-line telephone with a ground key or ground-start button is not
available, ground one side of the trunk.
To test ground-start trunks, follow the steps below:
Plug the single-line telephone into each central office line/trunk jack
! 
(either at the network interface or at the cross-connect field).
Pick up the handset.
! 
You should hear a dial tone.
Ground the ring lead by pushing the ground key or ground button,
! 
or by grounding one side of the trunk.
Remove the ground from the ring lead.
! 
Dial a telephone number to verify dialing.

Also check that you have good two-way transmission after the central
office completes the connection.
