Terminal cards are used for connecting digital and analogue voice and data termi-
nals such as:
FXS cards are an exception. Their analogue interfaces are multifunctional. In addi-
tion they provide interfaces for controlling external devices and switching over in-
ternal switch groups. Depending on the terminal or function, the interfaces are
configured individually and switched over internally accordingly (see
tional FXS interfaces", page
DSI cards are used for connecting digital system terminals such as phones. 2 termi-
nals can be connected to each DSI interface.
Terminals to ETSI standard are connected via BRI cards. The cards contain both ter-
minal interfaces (BRI-S) and network interfaces (BRI-T). On the BRI cards 4 interfaces
can be individually configured to BRI-S or BRI-T.
