This parameter specifies the type of the interface card capable of capture the specific signal. The call
recorder APRESA supports 3 types of interface cards:
ATP-type – Interface Cards:
-Interfaces to ANALOG signals. One card supports 8,16, or 24 channels.
DST-type - Interface Cards:
-Interfaces to DIGITAL (TDM or ISDN2) signals. One card supports 8,16, or 24 channels.
DTP-type – Interface Cards:
-Interfaces to DIGITAL signals. One card supports 1,2 or 4 trunk lines
= 30 channels E1 / trunk line or 24 channels for T1 / trunk line
Depending on the requirements of your implementation of APRESA, interface cards may be a
necessary part of your system. APRESA can hold up to 6 interface cards (4PCI+2PCIe) as absolute
maximum. A special chapter is dedicated to the specification of the interface cards.
For TETRA and VOIP recording NO special interface card is needed. These networks are Ethernet
based and both use the designated Ethernet port located on the PC motherboard.
