  1. Install a TN760 or a non-United States tie trunk circuit pack in the assigned carrier slot (if an additional circuit pack is required).

  2. For customer-owned (not leased) tie-trunk facilities (such as campus environments), TN760 circuit packs provide signaling capabilities beyond those specified by the industry-wide E & M standard. Use Tie Trunk Circuit Packs (Component Side) and Tie Trunk Option Switch Settings and Administration to choose the preferred signaling format, set switches on the TN760 circuit pack, and administer the port.

  3. Administer forms listed under Tie Trunk Group in DEFINITY Enterprise Communications Server Administrator's Guide.
