The TE220 is a with 2 ports, selectable E1 (32-channel) or T1 (24-channel) card that supports all the functionality of the quad T1 / E1 / J1 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 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.

The card is a compact and powerful interface supporting voice and data transmission over T1, E1, and Primary Rate ISDN (PRI) connections.

Of course, the asterisk card TE420 is fully supported by open source Asterisk PBX software. Used in conjunction with Asterisk, the card offers the power to create a seamless network, interconnecting PSTN with the emerging Voice-over IP technologies. The card can be used to deliver a wide range of PBX and IVR services to the network or handset including Three-Way Calling, Call Conferencing,Voicemail ,and VoIP Gateways.
