Digital Tie Trunk Example

Steps 1-3 of each example should have been completed in the Provisioning Plan in Chapter 2, "Plan and Prepare the Site", Step 8.

This example shows how to connect digital tie trunk wiring from one DEFINITY System Generic 3 to another DEFINITY System Generic 3:

1.Choose a peripheral to connect (such as DS1/E1)

2.Choose the port board to use and its carrier and slot number (such as TN464, Cabinet 1, Carrier C, Slot 06).

3.Choose a port circuit on the port board (such as Port 03).

4.Install cross-connect jumpers to connect the named pinouts from the Digital Trunk circuit pack to like-named pinouts on the manufacturer’s or supplier’s external digital trunk as shown in the following example. This pinout information is taken from Table 9-8 on page 9-16and Table 9-9 on page 9-17.

5.Set option switches on the port circuit pack (TN464 digital trunk) according to Appendix H, "Option Switch Settings".

6.Administer on the Digital Service Level 1 (DS1) and Trunk Group Screens of the G3 Management Terminal. See the DEFINITY G3 Implementation Guide for more details.

The wiring designations for this example are listed in Table 9-5,and are illustrated in Figure 9-6.
