Features
called on the associated voice device to be able to transmit digits (required by Global 
Call).
The following restrictions apply to D4PCIU boards:
• The boards will not function with any other board in the system, and must be the only 
board in the system. This is a permanent, stand-alone restriction.
• Transaction record is not supported.
• The Voice API library routing functions dx_getxmitslot( ), dx_listen( ), and 
dx_unlisten( ) are not supported. Calls to these functions will return the error, 
EDX_BADPROD. 
• When using the Device Management API dev_Connect( ) function for bridging 
between HMP and the board’s analog interfaces, be sure DM_ANALOG_INTF is 
added to the dev_Connect( ) function’s connType parameter. If this value is not 
added, the function will fail because bridging the on-board voice devices is not 
supported on these boards.
3.8.3 Important Considerations
CT Bus TDM routing for on-board voice and analog interfaces is now extended to and 
from HMP devices in order to provide media streaming.
Transaction Record
Transaction record enables the recording of a two-party conversation by allowing data 
from two time division multiplexing (TDM) bus time slots to be recorded with a single 
channel using the voice API dx_mreciottdata( ) function.
Note: Transaction record is not supported on the Dialogic
® 
D4PCIU boards.
With HMP and the Dialogic
®
 D/80PCIE-LS board, TDM bus time slots can be of two types: 
– CT Bus: Transmit TDM time slots from HMP-enabled analog or digital boards
– HMP soft Bus: Transmit TDM time slots from HMP media or IP devices
Transaction record remains a valid feature of the Dialogic
®
 D/80PCIE-LS board whenever 
voice data belongs to CT Bus TDM bus time slots; however, it is not functional when voice 
data from either of the two receive TDM time slots is from HMP soft Bus TDM bus time 
slots. 
In other words, if the valid channel device handle in the dx_mreciottdata( ) function is 
from a Dialogic
®
 D/80PCIE-LS board, the SC_TSINFO sc_tsarrayp values must contain 
two valid CT Bus TDM time slots from transmit TDM time slots from analog or digital 
network interface HMP-enabled boards. The function will fail when either of the 
SC_TSINFO sc_tsarrayp values belong to transmit TDM bus time slots from HMP host 
devices.
