7.8 Using The IMIST Module
An Impact SCS 8201N telephone equipped with the optional IMIST
module can support an IST device (modem, FAX machine,
industry-standard telephone, etc.) in addition to the telephone.
Depending on system programming, the IST device may be used to make
outgoing calls and receive incoming calls.
The functionality of the IMIST module depends on the type of system
you are using.
• On a DXP system, the IMIST module does not have its own
extension number and can not function simultaneously with the
telephone.
• On a DXP Plus system, the IMIST module can function
simultaneously with the telephone if your system has revision 5 or
later firmware. If your system has an earlier firmware revision, the
telephone and IMIST module can not function simultaneously.
• On an FX Series system, the telephone and IMIST module can
function simultaneously.
NOTE: The IMIST module does not provide voltage to light a message
waiting light. Message waiting lights on devices plugged into
the IMIST module will not function.
If you have any other questions about IST devices, refer to GCA70–237,
Industry-Standard Telephone Station User’s Guide.
NOTE: The IMIST card has a separate power supply. The wall
transformer is a UL and CSA approved Class 2 device
operating from 120 Vac, 60 Hz, 16 watts and provides an output
of 24 Vac at 450 mA. For replacement, order Comdial P/N
DIU-PTR.
