High-performance transcoding algorithm
Dedicated DSP resources
Seamlessly compatible with all Asterisk features
The CDC series is perfectly compatible with all Asterisk, helping Asterisk-based applications developers deliver cost-effective, feature-rich and highly accessible solutions.
PCI 2.2 Bus compliant
Includes PCI 2.2 bus with burst data transmission rate up to 132 MB/s; PNP (plug and play) feature eliminates the need for jumper leads; the universal PCI design supports 3.3V/5V PCI slot and PCI-X slot.
DMA data exchange
32-bit bus master DMA data exchanges across PCI interface at 132MB/s for minimum host processor intervention. The use of PCI-based DMA technique for data exchange minimizes utilization of the host CPU.
The dedicated DSPs process the codec translations among G.711 A-Law, 關-Law and G.729a, which minimizes consumption of host CPU in all demanding situations and guarantees high scalability when system expansion is required. Each can handle 50, 100, or 150 bi-directional decompression (a-law to G.729a) or compression (G.729a to a-law).
