ISDN BRI Interface Cards

The ISDN BRI S/T voice interface card provides a client-side (TE) ISDN S/T physical interface for
connection to an NT1 device terminating an ISDN telephone network. Each port on the interface card
can carry two voice calls (one over each ISDN B channel), for a total of four calls per ISDN BRI card.
ISDN BRI NT/TE voice interface cards (VIC-2BRI-NT/TE and VIC2-2BRI-NT/TE) have the same
capabilities as the S/T card, but can also be configured to provide a network termination (NT) interface
with phantom power.
