Assigning Telephone Buttons

Guidelines for Button Assignments

Use the following guidelines for assigning buttons to telephones or to adjuncts
connected to an MLX telephone.
NOTE:
When assigning buttons to telephones or adjuncts, keep in mind that BRI lines
are not automatically assigned to telephones or DLCs.
For multiline telephone users:
You can assign SA Voice, SA Ring, and SA Orig Only buttons and up to
27 SSA/SA buttons to each telephone. However, use the factory setting
of 3 to ensure that when each user is busy on a call at least one
additional button is available to receive a call and another is available to
make a call. This leaves the rest of the buttons on multiline telephones
free for customizing.
NOTE:
On a DLC, there can be 10 System Access buttons (including SA Orig
Only), but no SSA buttons. On a QCC, no buttons can be programmed,
however, if the QCC Voice Announce feature has been enabled, the
Call5 button becomes a VA (Voice Announce) button.
If you plan to use Automatic Route Selection (ARS), consider keeping the
factory-set button assignments. Since ARS picks the appropriate route,
there is no need for Pool buttons.
Consider assigning SSA buttons to small groups of users who need to
answer and distribute each other's calls easily or to join conversations.
Each SSA button you assign corresponds to an SA Ring or SA Voice
button on another telephone. Therefore, to provide complete coverage
within the group, you must be sure that each SA Ring and SA Voice
button assigned to a telephone is also assigned to other members of the
group. Each SA Ring or SA Voice button on a telephone can be
assigned as an SSA button on up to 16 other telephones.
Assign a Pool button when a specific trunk pool (for example, BRI, WATS
or FX) is used frequently. Also consider assigning Pool buttons if you do
not plan to use ARS and the system includes only one or two pools.
Assign personal line buttons when an exclusive private number is
needed, for example, for a company executive. Any line/trunk connected
to the system can be used as a personal line as long as it is not in a trunk
pool.
For single-line telephones, answering machines, fax machines, or any other
device connected to an 012, 016, or 008 OPT module:
The settings for SA buttons can be changed (see below); however,
factory settings should be adequate to meet most user needs, since SA
buttons can be used to make and receive both inside and outside calls.
