Adding, Removing,
and Modifying
Telephones
This section describes how to add, remove, and modify system telephone
devices. You can also review the status of each device and configure
button mappings for NBX telephones.
Adding a New
Telephone
You can configure a new telephone in two ways: using Auto Discovery or
manually.
■
Auto Discovery method — Auto Discovery is the simplest and most
common method of adding a new telephone. When you enable Auto
Discovery and then connect a new NBX Business or Basic Telephone to
the LAN, several messages pass between the Call Processor and the
telephone. The result is that the new telephone receives a default
telephone number, which appears on the telephone’s display panel.
The telephone receives the next lowest available extension and a
default set of properties. For instructions on how to connect a
telephone to the LAN, see “Connecting the NBX Business or Basic
Telephone” later in this section.
■
Manual method — You can disable Auto Discovery and configure
telephones manually using the NBX NetSet utility. However, if you
have many telephones to configure, manual configuration can be a
tedious and error-prone process.
For either method of adding a telephone, you must connect the
telephone to the network. If you use Auto Discovery, you must enable the
Auto Discover Telephones check box
before you connect the telephone. If
you add a telephone manually, it does not matter whether you connect
the telephone before or after you use the NBX NetSet utility to add it.
Connecting Power to the Telephone
Connect the AC power converter provided with each telephone to the
power connection on the underside of the telephone and then connect
the other end of the power converter to an AC power outlet.
Connecting the NBX Business or Basic Telephone
To connect the telephone:
1 Connect a Category 5 Ethernet cable to an available hub port or wall jack
that is connected to the same subnetwork as the NBX Network Call
Processor.
2 Connect the other end of the Ethernet cable to the LAN connector on the
underside of the telephone, as shown in Figure 44.
