The PRI Server Card provides flexible access and routing of PRI-based ISDN services. The ISDN PRI Server can be used for enabling applications such as Video Conferencing, Video Broadcast, ISDN Grooming, and Fractional PRI provisioning. The PRI Server card supports B channel bandwidth of 56K, 64K, 384K, 1536K and Multi-Rate speeds where available. Multi-Rate speeds allow the PRI server card to select calls in increments of 64Kbps. In areas where Multi-Rate is not supported by the local ISDN switch, an Inverse Mux (IMUX) Server Card should be used to aggregate individual 64Kbps calls.
