O VERVIEW
The Syn248Business Phone System from AT&T is for businesses that need up to 24
extensions. This system is scalable from 1 to 8 outside lines, so as your business grows,
your phone system can too. The Syn248 Business Phone System provides simplicity
without sacrifice—it's simple to install, manage, and use, without sacrificing any of the
features you need and expect from a business telephone system.
This chapter introduces the SB35020 Deskset and provides an overview of the Syn248
System and the external features of the Deskset.

Syn248 System Overview
Your Deskset is part of the Syn248 System. Syn248 differs from conventional telephone
systems in that calls are not coordinated by a central controller. Instead, Syn248 uses a
distributed control system over a Local Area Network (LAN). Figure 1 illustrates a sample
system.

Lines and Line Keys
The system administrator can configure your Deskset with up to 8 lines on which you can
make and receive external calls. Each line is assigned to a Programmable Feature Key on
the Deskset. These are called Line keys in this User’s Guide. One Programmable Feature
Key is reserved for “Intercom” calls to other Deskset extensions.
Other Desksets in the system share these lines and display the line status. Incoming calls
on a line ring at all Desksets that share that line. The Line key LED indicates whether a
line is ringing, busy, or on hold.
The Line keys are used for receiving and making calls to external numbers. To call
another extension in your office, you must use an Intercom key. By default, the Intercom
key is the bottom Programmable Feature Key, but your system administrator can
configure additional Intercom keys.

Setting Your Password
You can protect your Deskset by setting a password that prevents other users from
accessing your User Settings and Voicemail. If you create a password, you will need to
enter it before accessing User Settings, Voicemail, and the WebUI.

Soft Keys
Soft keys are a set of three context-sensitive keys that provide functions based on what
you are doing on the Deskset. The top example as illustrated in Figure 5 shows the soft
key labels on the active call screen.
The soft key labels change according to the current task. For example, if you are holding
a call, the key labels displayed are different from those displayed if you are making a call.
See “Appendix A: Soft Keys” on page 110 for an alphabetical list of the labels that appear
above the soft keys.
The top example shows the soft key labels for the soft keys on the active call screen.

M AKING C ALLS
The SB35020 Deskset provides several methods for making a call. If you are in Idle mode
or have calls on hold, you can predial a phone number and then go off hook to call the
number. You can make a call at any time by choosing an off-hook method, then dialing
a number. This is referred to as Live Dialing. You can also predial or live dial using phone
numbers from lists, such as the Directory, Call Log, Redial, Quick Dial, and Messages.
You can dial the extension for the system operator by pressing 0(zero).
