Trunk cards

The trunk cards contain interfaces for connection to the analogue public network
(POTS), the digital public network (ISDN) or for networking systems to create a pri-
vate telephony network (PISN). The trunk cards can be used and operated on any
slots for interface cards.
On trunk cards with S and T interfaces the ratio of S to T interfaces is determined by
the use of and the plug-in orientation of the wiring adapters (see
page 78).
