3 TELEPHONES AND ATTENDANT CONSOLES This chapter explains how to install: ■ 3Com Telephones ■ 3Com Attendant Consoles For information on how to add a 3108 Wireless Telephone or a generic SIP telephone to an NBX system that is running in SIP mode, see the NBX Administrator's Guide. WARNING: 3Com Telephones are intended for connection only on internal Local Area Networks. Do not install them outside of buildings. Adding Telephones There are two ways to add a new telephone: Auto Discover, and manual configuration. Auto Discover Telephones Auto Discover is the simplest and most common method of adding a new telephone. When you enable the Auto Discover feature and then connect a new 3Com Telephone to the LAN, the telephone receives the next lowest available extension and a default set of properties. You can then move the telephone to another location on the LAN and it retains its extension number. For instructions on connecting a telephone to the LAN, see "Connecting the Telephone to the LAN" on page 126. It is good installation practice to add telephones one at a time, label each with the extension number assigned by the Auto Discover process, and then disconnect them. Extensions are assigned in sequence starting with extension 1000 on a four-digit dial plan and extension 100 on a three-digit dial plan. You can see the extension associated with the new telephone on the telephone's display panel (except for the 3100 Entry Telephone). You can see and change the extension number in the Telephone Configuration > Telephones page of the NBX NetSet utility. You can use the telephone's MAC address to match a physical telephone
