13. Check all wiring to verify good connections between the two test ports.
14. Place a call from one voice terminal to another voice terminal using the Tie
Trunk ports assigned. Dial TAC and extension. For example, if TAC of Tie
Trunk group is 110 and station number is 5012, then dial 110 5012. If the
call cannot be made, either one of these ports could be defective. There
are four ports on TN760B (port 1, 2, 3, and 4), try different combinations to
determine defective ports.
15. If there is a defective port on the circuit pack, try to switch to an unused
port. However, if all ports are normally used, then replace the circuit pack.
16. Disconnect the jumpers between two ports. Then use administration
terminal and trunk printouts to restore all trunk group changes to normal
values.
