Extension in Use notification on the
telephone
Line indicator lights let you know whether a line is
available for you to use. When another extension is using
a line, the line indicator light for that line (located beside
the line key) turns on. To see the location of the Line
indicator lights, refer to The M9617 telephone keys
and lights on page 29.
When you are on a call and someone on an extension
telephone tries to use your line, the set indicator light (the
˚
light above the key) turns on. The light
remains on and the message Extension in use appears
until the person at the other extension hangs up.
Extension in Use and the Fax switch feature
©
When you lift the handset or press , the 9617
telephone automatically selects the prime line (for
information on the prime line feature, see Changing the
prime line on page 240).
If your prime line is Line 2 and a fax switch peripheral
device (e.g,. a fax machine) is using that line, Line 2 is not
selected when you pick up the handset. Instead, the
message Extension in use / Press line key appears on
the telephone display.
ø
Then, if you press , you access Line 1 and can
π
make a call. If you press , you access Line 2
and may interrupt the call to the peripheral.
For more information, refer to Extension in Use
notification in Personal Call Manager on page 73.
