Analog Tie Trunk Example

3.Choose a port circuit on the port circuit pack (such as Port 02).

4.Set option switches on the port board (TN760 tie trunk) as described in Appendix H, "Option Switch Settings".

5.Install cross-connect jumpers to connect the named pinouts from the tie trunk circuit pack to the appropriate leads on the external Tie Trunk. Names of the Tie Trunk leads must be determined from the manufacturer or supplier of the external trunk circuit. The example in Figure 9-5and Table 9-4shows a DEFINITY System Tie trunk connected to a DEFINITY System tie trunk. For tie trunk TN760, refer to Table 9-8and Table 9-9.

6.Administer on the Trunk Group Screen of the terminal. See the DEFINITY G3 Implementation Guide for more details.

The wiring designations for this example are listed in Table 9-4and are illustrated in Figure 9-5.
