Assigning Telephone Buttons
For non-operator multiline telephones, you can assign SA Voice, SA Ring,
and SA Orig Only buttons to the first 10 buttons on each telephone, and up
to 27 SSA buttons to each telephone. However, it is recommended that the
factory setting of 3 SA buttons be used 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.
An extension can have SSA buttons for another extension, but it must have
at least one SA button for itself. For example, Extension A has 10 SA
buttons. Extension B can have SSA buttons for up to 9 of the 10 SA
buttons on Extension A; the remaining button is for B's own SA button.
On a DLC, there can be 10 SA buttons (including SA Orig Only), but no
SSA buttons. The factory setting for SA buttons is 2. It is recommended
that additional SA buttons be added to ensure that the operator can
transfer calls.
On a QCC, no buttons can be programmed. However, if the QCC Voice
Announce feature has been enabled, the Call 5 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 join conversations. Each
SSA button you assign corresponds to an SA Ring or SA Voice button on
another telephone. To provide complete coverage within the group,
therefore, 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. Do not
assign network pools to telephones.
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.
Do not assign network trunks to telephones.
For single-line telephones, analog modems, fax machines, or any other device
connected to an 012 (T/R), 016 (T/R), 016 ETR, 008 OPT, or 412 LS-ID-ETR
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.
