NBX Tones

As you use your 3Com Telephone to receive voice mail and use the

 

feature codes on the NBX system, you hear these tones:

 

■ Dial Tone — When you lift the receiver to place a call or begin using

 

one of the features, you hear the normal Dial Tone (except for the

 

circumstance described in the next bulleted item).

 

■ New Messages Dial Tone — When your voice mailbox has either

 

new or unsaved messages and you pick up your handset, you hear the

 

New Messages Dial Tone (a repeated short tone, also called the

 

“stutter” tone) until you delete or save every message. Your

 

administrator can turn the New Messages Dial Tone on or off.

 

■ Feature Entry Tone — When you lift the handset and press the

 

Feature button to begin using one of the features, you hear the

 

Feature Entry Tone, which is a steady sound at a lower pitch than the

 

normal dial tone. You must enter data, for instance a feature code

 

number, your password, or an extension, as specified in Table 9.

 

■ Confirmation Tone — After certain steps, as when you add a party

 

to a conference call, you hear a short Confirmation Tone or “beep,”

 

which confirms that you have completed the action.

 

■ Error Tone — You hear the “fast busy” tone, also called the

 

“congestion” tone, when no circuits are available. In addition, you
