The B410P enables Basic Rate ISDN S/T connectivity for Asterisk users outside of North America and connects eight digital voice channels (four ISDN lines for a total of eight B-channels) per card to an Asterisk server.

The B410P is a half-length, full-height universal 3.3V and 5.0V 32-bit PCI 2.2 card supporting four BRI S/T interfaces. Each of the four ports of the B410P can be independently configured for TE or NT mode, with an optional PWR400M module for supplying power to ISDN telephones. The B410P features on-board hardware echo cancellation performing 64ms or 512 taps per channel for each of the eight voice channels.
