New version, our second generation digital cards.
Supporting EC Module with Octasic EC chip.
Specifically designed for the Asterisk platform, available for Freeswitch, Yate and other open source project.
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.
Driver optimization: Specifically optimization for high volume data transmission in drivers.
his 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.
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..
