Terminal cards
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
"Multifunc-
tional FXS interfaces", page 127
).
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 these cards the ratio of
BRI-S interfaces to BRI-T interfaces is determined by the type and plug-in orienta-
tion of the Wiring Adapters (see
"Wiring Adapter", page 98
).
