7.8 Using The IMIST Module
Impact SCS 8212S-** and 8212N-** speakerphones equipped with the
optional IMIST module can support an IST device (modem, FAX
machine, industry-standard telephone, etc.) in addition to the
speakerphone. Depending on system programming, the IST device may
be used to make outgoing calls and receive incoming calls.
The functionality of the IMIST module is similar to the optional Data
Interface Unit (see Section 7.7).
Functioning only on a DSU II system, the IMIST module does not have
its own extension number and does not function simultaneously with
the speakerphone.
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 module 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.
