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 133).
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 "Fitting a wiring adapter", page 102).

Wiring adapter
The wiring adapters route the interfaces of the various interface cards with the right
connection diagram to the RJ45 sockets on the front panel. The adapters are fitted to
WA1...WA4 sockets.
