D.1.1 Operating the SX2 cards in NT Mode
This chapter describes how to use the SX2 card in NT mode to connect ISDN devices and telecommunication systems to SwyxWare. These descriptions include the hardware requirements, any restrictions of the supported devices and the required configuration options of the SX2 cards and SwyxWare.
Supported devices on the Basic Rate Interface (BRI)
The SX2 QuadBRI can be used in NT mode. Multiple-subscriber lines and direct-dialing-in lines will be supported. Telecommunication systems with Basic Rate Interface, terminal adapters for transferring the ISDN interface to an analog line or ISDN phones can be connected to the cards. When using the SX2 QuadBRI a connection to up to 4 Basic Rate Interfaces of a telecommunication system is supported at the same time.
* 
Only ISDN phones with a separate power supply such as cordless phones can be connected to the ISDN cards. Simple ISDN phones which can be connected to the power supply only via the ISDN interface can not be connected.
 
It is also possible with the help of "BRI-BUS Power-Adapter to feed power to the BRI-bus (EXSG10001)" to apply a current to the BRI bus and thus to supply terminal devices. The computers power supply (mains) is used for this.
Supported devices on the Primary Rate Interface (PRI)
The use of the SX2 SinglePRI or SX2 DualPRI in NT mode is supported by the driver software of the card. A direct dialing-in telecommunication system with Primary Rate Interface can be connected to the ISDN card.
