The new AVM ISDN-Controller B1 PCI v4.0 sets new standards for basic-rate ISDN in professional server and workstation applications. Equipped with a high-performance, 50-MIPS StrongT processor, a completely new development by AVM, the ISDN-Controller B1 PCI v4.0 provides a CAPI 2.0 interface for a great number of current operating systems, and features universal compatibility through support for numerous D and B-channel protocols, including Group 3 fax. The active design and the use of bus-mastering DMA ensure a minimal load on the host system and maximum reliability.
