3. 3. 2. 2 Terminal cards
Terminal cards are used for connecting digital and analogue voice and data terminals
such as:
FXS cards are an exception. Their analogue interfaces are multifunctional. In addition
they provide interfaces for controlling external devices and switching over internal
switch groups. Depending on the terminal or function, the interfaces are configured in-
dividually and switched over internally accordingly (see "
Multifunctional FXS inter-
faces", page 127).
DSI cards are used for connecting digital system terminals such as phones. 2 terminals
can be connected to each DSI interface.
Terminals to ETSI standard are connected via BRI cards. The cards contain both termi-
nal 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 orientation of the
Wiring Adapters (see "
Wiring Adapter", page 98).
