AT&T Partner II - Manual (Page 59)

Some features require buttons with lights. Other features do not require buttons
with lights, but do use the lights to show status information if they are available.
For features that can be turned off and on by the user (such as Do Not Disturb
and Privacy), the features are on whenever the lights are on.
NOTE:
The lights on MLS-model phones do not show status information for Centrex
features.
Information on programming equipment features is provided on page 5-16.
Here are some specific features you might want to store on programmable
buttons:
■

■
■

Voice paging of specific extensions
Voice paging of Calling Groups
Extension jack numbers for frequently-dialed extensions inside your
system (so that users can call with one touch, talk without tying up their
primary lines, and monitor the status of that extension).
Message Light On and Message Light Off
Privacy and Do Not Disturb, which require buttons with lights
Recall, to send a switchhook flash for accessing Centrex features while
on a call.
Intercom Calling
If you store an extension jack number on a programmable button at an MLS- or
MLC-model phone, you can use the button as a Direct Station Select (DSS)
button, to call the extension with one touch, simply by pressing the button. This
enables you to call the extension using the intercom, so you can make an inside
call without tying up your primary line (as well as the primary line for the person
you are calling). (See Appendix B for details on intercom calling.)
In addition, the lights next to the button act as Busy Lamp Fields (BLF) that show
calling activity for the extension:
Idle (no lights) ■
■ Busy (red on)
■ Calling you using the intercom (green flash).
If the extension is identified as a fax extension, the button also shows a red
broken flutter when the fax is not responding (for instance, when it is out of
paper).
This equipment feature is called Call Viewing. You may wish to use Call Viewing
at any covering extension (for example, at the receptionist’s phone), so the
person at the covering extension can monitor calling activity at covered
extensions by looking at the Intercom Calling buttons. Since Call Viewing
requires buttons with lights for each extension covered, an MLS-34D, MLS-12,
or MLS-12D phone is recommended for this function.
