Installing The Personal Computer Interface Unit
Introducing The Personal Computer Interface Unit
The Personal Computer Interface Unit (PCIU) is a device that you can connect between a digital station port and
its proprietary telephone. The PCIU allows telephone users to initiate telephone-related functions from their
personal computers (PC). Applications such as this are commonly known as Computer Telephony Integration
(CTI) applications. The PCIU will function with Comdial digital telephone systems (the DSU and DSU II
systems) and Comdial digital communications systems (currently the DXP, DXP Plus, and Impact FX systems).
The PCIU includes Service Provider Interface (SPI) software on computer floppy disks. When you install this SPI
software on a PC, the PC users can employ their Telephony Applications Programming Interface (TAPI),
third-party, Microsoft Windows* applications programs to control many useful telephone functions.

The PCIU comes bundled with wideopen.call software. Wideopen.call is a CTI application that offers on-screen
call management and a detailed call log.
