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 "Wiring Adapter",
page 98).
Note
On the ESST terminal card the jumper must always be fitted in position T (see Fig. 24).
