Special Information About
Square Systems
In a square system you must give special attention to the way 5-button voice terminals
operate. These voice terminals accommodate a maximum of three outside lines, and
the same three must be assigned to all 5-button voice terminals in your business.
The three lines are those that are plugged into control unit jack numbers A0, A1, and
A2. You cannot assign different sets of lines to different 5-button voice terminals. This
means that people who have 5-button voice terminals cannot use any lines other than
these three to answer or make calls. Furthermore, calls that come in on other lines
cannot be transferred to 5-button voice terminals by the normal Transfer method. Here
are some tips on maximizing the usefulness of your 5-button voice terminals:
If you expect people with 5-button voice terminals to answer incoming calls, either
directly or via transfer, make sure that most outside calls come in on the lines
connected to control unit jacks A0, A1, and A2. You can do this by listing the
number of the line connected to intercom jack A0 in the telephone directory as
your business telephone number. This works particularly well if you have the
type of arrangement with your local telephone company whereby one number
is listed in the telephone directory, but if that number is busy, incoming calls
are automatically transferred to any of several other lines.
If people who use 5-button voice terminals need to place many outside calls,
you can make the lines on their voice terminals more available to them by pro-
gramming the Automatic Line Selection sequence on larger voice terminals
"backwards" — that is, selecting lines other than those on 5-button voice ter-
minals first. For example, you would select the lines plugged into control unit
jacks A3, A4, B0, B1, B2, etc. before those plugged into jacks A0, A1, and A2.
If any 5-button voice terminal users need access to a special line such as a WATS
line, be sure that it is plugged into control unit jacks A0, A1, or A2; otherwise
it won't appear on 5-button voice terminals.
There is a way to switch a call to a 5-button voice terminal from a line that it
does not have:
—The person who wants to transfer the call can use the Conference button
with Intercom to conference together the line the call came in on and the
5-button voice terminal user. Once everyone is connected, the person who
received the call originally can put the conference on hold, then hang up and
the other two people can continue speaking with one another.
If you have many 5-button voice terminals in your business and find that having limited
line access is a problem, you can solve the problem by switching to a pooled line
arrangement.
