Voice files stored on the host PC are read by the host driver and transferred to the 
Dialogic

®

 PBX Integration Board via the PCI Bus. These voice signals are 

buffered by the control processor and decoded into 64 Kbps PCM signals by the 
DSP. These PCM voice signals are then sent to the PBX interface link for 
transport to the caller. A system-wide, TDM signal sharing bus, called CT Bus, is 
also provided for the exchange of signal streams with other resource boards, 
signal transport boards, or other interfaces. 

In addition to having all the standard features of a Dialogic

®

 D/41D Board, the 

Dialogic

®

 PBX Integration Board can access enhanced PBX features, when 

available, such as: 

•  call transfer/conference 

•  turn phone message waiting indicators on or off 

•  callback request 

•  calling number identification (Calling Number ID). 

The Dialogic

®

 PBX Integration Board has an on-board microprocessor and a 

high-speed Digital Signal Processor (DSP) to provide voice and call processing.
