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.
