ISDN Voice Interface Cards (VICs) connect directly to Public Switched Telephone Networks (PSTNs), Private Branch Exchanges (PBX), and Private Access Branch Exchanges (PABX), supporting both on-premise and off-premise connections. The VIC2-2BRI-NT/TE cards are new generation VICs that are a hardware refresh of the older cards of the similar functionality, with resolved manufacture component issues. ISDN BRI NT/TE voice interface card (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.
