Flexible dialing restrictions and permissions so you can control telephone activity and phone bills.

Special hospitality features that let Bed and Breakfast proprietors, for example, regulate phone use in guest rooms and schedule wake up calls for guests.

Easy-to-use programming procedures, making it simple for you to manage your system and telephones. System display phones provide feedback during programming.

Two system programming extensions, allowing you to program the system from one extension without interrupting call activity at the other programming extension—usually the receptionist’s extension.

Modular connections to the control unit, making it simple to reconfigure your system or to add lines and/or extensions as your business grows.

Direct connections for industry-standard devices—including most standard phones, fax machines, answering machines, modems, and credit card scanners.

Optional equipment support, including doorphones, loudspeaker paging systems, music on hold*, call reporting (often referred to as Station Message Detail Recording or SMDR) devices, PARTNER Attendants, and extra alerts.

System Components

Modular hardware design makes the system easy to install and expand. Figure 1-1shows an example of system components.

Control Unit

The control unit is the heart of the system; it is made up of one or two carriers, and it houses the system modules. You can use either the primary carrier, or the primary carrier and the expansion carrier if you need more lines and extensions. Each carrier housing includes a backplane and a cover. All system modules slide into the backplane, which channels power to the system. The cover slides onto the front of the backplane after all the system modules have been installed.

WARNING:

There are no customer-serviceable components inside the system modules or backplane. There are hazardous voltages within that can cause severe or fatal personal injury. DO NOT OPEN THE MODULES.
