1.Plug the single-line telephone into each central office trunk jack (either at the network interface or at the cross-connect field).

3.

4.

Pick up the handset.

You should hear a dial tone.

Ground the ring lead by pushing the ground key (or button) or by grounding one side of the trunk.

Remove the ground from the ring lead.

5.Dial a known telephone number to verify dialing.

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

6.If you find a central office trunk that does not have a dial tone, check for a bad adapter or loose connections.

7.If adapters and wiring are in working order but you still don’t hear a dial tone, notify the customer.

8.If outward dialing is not possible on any of the trunks, notify the customer.

NOTE:

It is the customer’s responsibility to report service outages to the local telephone company.
