When a call comes in to the manager on that extension, the assistant’s 
telephone rings 4 times before the call audibly rings on the manager’s 
telephone. Even during the first silent rings, the line’s status light on the 
manager’s telephone flashes, allowing the manager to answer the call if 
required.

In some locations, analog telephone users must dial telephone calls using 
pulse dialing instead of tone dialing (also called Dual Tone Multi 
Frequency, or DTMF, dialing).

■

Some of your telephone lines are provided by a telephone company 
that supports only pulse dialing while other lines are provided by a 
different telephone company that supports DTMF dialing.

■

Your organization’s telephone service provider offers low-cost, 
pulse-dialing-only service.

■

In some situations, you must switch to DTMF dialing during a call. For 
example, if your call is answered by an automated attendant that 
requires that you enter information from your telephone keypad, you 
must typically enter the information using DTMF dialing.

To change from pulse dialing to DTMF during a call:

1 Press the Feature button and 891.

2 Your connection is switched from pulse to tone (DTMF) for the remainder 

of the call. When you hang up, the port you were using on the Analog 
Line Card reverts to pulse dialing mode.

Your administrator can map a button on your telephone so that you can 
press the button to change from pulse dialing to DTMF during a call. 
When you hang up, the port that you were using on the Analog Line 
Card reverts to pulse dialing mode.

You can configure a personal speed dial in the NBX NetSet utility to dial a 
number in pulse dial mode and then to switch to DTMF. Use the left 
angle-bracket character (<) in the NBX NetSet utility as the command to
