The Intelligent ISDN TA PC Card comes with either a U-interface or S/T-interface network connection
cable. The U-interface connection cable is for direct ISDN line connection, which does not need any extra
ISDN NT1 device.
The S/T-interface connection cable is for connecting to NT1. Both U- and S/T-interface use RJ45 phone
jacks, but with different pin assignments. The bundled RJ45 phone cord can be used for both U- or S/T-
interface connections.
