Program 20 Overview
Program 20 identifies the digital station ports connected to RPCI/PDIU and the type of PDIU
connected.
RPCIs have two modes: the Data Switching (DIU mode) and the Application Program Interface
(or TAPI) mode. In the DIU mode, the RPCI operates as a PDIU-DI (Integrated Data Interface
Unit); all Program 20 options apply except LED 10 and LED 11 - which only apply to the RPCI in
TAPI mode. In TAPI mode the RPCI does not require Program 20 assignments, except for LED 10
and/or LED 11 if ANI, DNIS, and/or Caller ID must be sent from the RPCI-DI to the PC to which
it is connected.
Notes
● RPCIs and PDIUs cannot be connected to PDKU1 circuit 8, but can be connected to all eight
PDKU2 circuits. RPCIs and PDIUs that support data switching cannot be connected to PDKU
in all slots. See DK424 Chapter 4 – DK424 Configuration, Tables 4-4 and 4-5. DK40i slots 17
and 18 do not support data switching.
