The HC Bridge SRC provides 256 bi-directional channels of sample rate conversion for AoIP networks. HC bridge SRC facilitates connecting audio between devices running at different sample rates or in different clock domains on a Dante (48khz and 96khz), AES67 or ST 2110-30 networks. The two network connections can be physically or virtually separate networks, providing control isolation between two sets of equipment where an “AoIP discovery and control firewall” is required. A HC bridge SRC includes 2 HC cards, each HC card provides 512 Tx and 512 Rx channels at 48khz, 256 Tx and 256 Rx at 96khz, with 128 Tx and 128 Rx streams at all sample rates. Each card includes redundant pair SFP cages for RJ45 or fibre Dante/AoIP connectivity.
