FXS, FXO, and E&M Interface Card LEDs
Each voice interface card has IN USE LEDs, one for each port. These LEDs have three states: green
when active, off when ready for use, and amber when not ready for use.

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.
