SinoV-420D Asterisk card T1/J1/E1 card/voip card PCI

The SinoV-420D is a with 4 ports, selectable E1 (32-channel) or T1 (24-channel) card that supports all the functionality of the Digium quad T1/E1 card. This card supports both voice and data modes on its single span. For example, the card can support 12 channels dedicated to voice and 12 to data while passing all traffic through to the Asterisk PBX, which reliably routes the channels to their designated locations. This eliminates the need for an external router.



By utilizing our TDMoE technology, an exclusive Digium process, one can easily connect multiple PCs equipped with the card and achieve voice quality on par with single PBX implementations. Scalability for this product is derived from adding multiple cards to each individual PC. Add addition cards as you need them for your expanding applications.
The card supports industry standard telephony and data protocols, including both RBS and Primary Rate ISDN (PRI) protocol families for voice and PPP, Cisco HDLC, and Frame Relay data modes. The board drives both line-side and trunk-side interfaces, including call features.
