receive and transmit simultaneous voice 
and data; data and voice calls can be 
made independently of each other. The 
PDIU-DI (Figure 5) is easily installed, 
replacing the usual digital telephone base.

It is normally used on systems with a heavy 
volume of incoming calls. A DDSS console 
may be used with any digital station connected 
to the first circuit on the digital telephone inter- 
face PCB (PDKU). Up to four DDSS consoles 
can be supported with a PCTU3 PCB.
