| Overview:
The EU24BL is an add-on
unit that works in association with a 4620, 4620SW, 5620 and 5620SW.
The EU24BL provides an additional 24 programmable buttons with associated
display label and status icons. Only one EU24BL per phone. The EU24BL
provides a backlit display. Although the EU24BL Expansion Module
supports an additional 24 Call Appearance/Feature buttons, it displays
only the button labels for one column of 12 buttons at a time.
A dotted
line separates the left column from the right column. When you view
the labels and icons for the left column, the icons for any active or
selected right column features display to the right of the dotted line.
To view the column not currently displayed, press the Alternate Display
button. You can alternately press any Call Appearance/Feature button
on the column not currently displayed. Doing so displays that column
and selects the line/feature associated with the button you pressed.Each
IP Office DS module, including control units with integrated DS ports,
supports a maximum of eight EU24 or eight EU24BL or two XM24
or two 4450 units only. If using an EU24BL with only IP telephones the
IP Office will support up to 8 EU24BL modules per IP Office switch.
Note:
The EU24BL does NOT work with either the 5420 or 2420.
