Efficient: Optimization of DMA transmission and hardware switching.
Clock: Support the master-slave clock. So several different carriers can be connected simultaneously.
Interfaces: Mixing T1/E1/J1 have been supported.
Line coding : HDB3 / AMI / B8ZS
Frame format : CRC4 / non-CRC4 / ESF / D4T1 / E1
HDLC Processing: Independent hardware HDLC transceiver
Driver optimization: Specifically optimization for high volume data transmission in drivers
Our new analogy card series includes the following 4 models:
This series provides full-duplex telephone card data with 1 6.384M transfer rate or 120-channels voice communications. Each machine can support multiple cards, particularly suitable for the development of Asterisk-based applications.
The card provides a wealth of line encoding (AMI / BSZS / HDB3), hardware frame processing(CRC4 / non-CRC4 / ESF / D4T1 / E1). Every card provides two independent HDLC transceiver and support SS7 FISU transmit-receive. The card also provides two independent Jitter Attenuator.
The card reserved slot for echo cancellation. Carrier-grade EC modules have been provided. The EC module also can provide optimizing of voice quality.
These cards supporing rich media processing with high performance. All the cards in one host can share the same clock source°£
The card provides 32bits transmission in both DMA slave and master mode. The data in every DMA transmission can be adjusted according to different motherboard to reach the maximum performance.
The optimization driver has been provided and has passed our rigorous testing
