The model XE telephone system is full featured, and
supports a specially designed group of multiline and
single-line proprietary telephones (product code series
of 67xxx-xx) described on page 1-6. It also supports
ExecuTech multiline telephones with product codes of:
6614E, 6614T, 6620E, 6620T, 6414 and 64148. (If a
product code 6414S-xx is used, a moderate volume
setting may be required to avoid the possibility of a
squeal being sounded through the station speaker
during call announce and/or background music
operations.) Along with the proprietary telephones,
the XE system supports the use of industry-standard
telephones (such as the Comdial2500) at two of its
station ports (ports 26 and 28).
An LCD upgrade kit that includes an integrated circuit
clock is available for the XE system to allow it to
support the operation of an ExecuTech LCD
speakerphone (product codes 6700s or 6600E). The
product code for this LCD upgrade kit is PCCXI. This
kit is available through normal distribution channels for
field installation by trained technicans. The product
code of the XE system changes from Nxxxx to Kxxxx
when the technician installs the LCD upgrade kit. The
new product codes become K0820 and Ml 024.
The LCD speakerphone provides the following feature
displays for the user’s convenience:
Time and Date
Call Duration Time
Do Not Disturb

A software upgrade kit is available for field installation
by trained technicans. The EPROM chip supplied in
this kit will revise the operating system software of the
XE system to the latest factory issued level. The
product code for the software upgrade kit is:
PSUXI-2 for NO820 and N1024
The software upgrade kit is available through normal
distribution channels.
