Trunk cards
The trunk cards contain interfaces for connection to the analogue public network
(PSTN), the digital public network (ISDN) or for networking systems to create a private
telephony network (PISN). The trunk cards can be used and operated on any slots for
interface cards.
Some trunk cards contain both network interfaces (BRI-T) and terminal interfaces
(BRI-S). On these cards the ratio of BRI-S interfaces to BRI-T interfaces is determined
by the use and plug-in orientation of the wiring adapters (see "Fitting a wiring adapter",
page 102).

Terminal cards
Terminal cards are used for connecting digital and analogue voice and data terminals.
FXS cards are an exception. Their analogue interfaces are multifunctional. In addition
they provide interfaces for controlling external devices and switching over internal
