Chapter 18 — Connecting the trunks

This chapter describes how to connect trunks directly to the trunk card, with or without the use of a Power Failure Transfer Unit (PFTU). This chapter contains the following procedures:

•Procedure 39: “Connecting trunks without a PFTU” on page 254

•Procedure 40: “Connecting trunks with a PFTU” on page 254

•Procedure 41: “Activating a default model trunk” on page 275

•Procedure 42: “Activating a selected model trunk” on page 276

The QUA6 PFTU operates with loop start and ground start CO trunks. However, with ground-start trunks the related telephone set must have a ground-start button.

During initial software installation on the Option 11C Mini, you can load a default database, containing preprogrammed trunk data, into software. If necessary, you can modify the default data at any time to meet the specific needs of a customer. For a description of how to modify preprogrammed trunking data, refer to “Appendix A – Preprogrammed data” on page 285 in this Guide.

WARNING

Always use caution when installing or modifying telephone lines. Avoid installing telephone wiring during a lightning storm. Do not install telephone jacks in wet locations unless the jack is designed for wet locations. Never touch uninsulated telephone wiring unless the line is disconnected at the network interface.
