TE410 4 Ports 3.3V PCI ISDN BRI Digial voip card + hardware VPMOCT128 Echo Cancellation Module

TE412P 4port PRI T1 E1 with VPMOCT128 echo cancellation module for Digium Asterisk The TE412P supports E1, T1, and J1 environments and is selectable on a per-card or per-port basis. This feature enables signaling translation between E1, T1, J1 equipment and allows inexpensive T1 channel banks to connect with E1 circuits. Because the TE412P improves I/O speed by up to 10 times, the result is reduced CPU usage and increased card density per server. The TE412P supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, also included are advanced call features. The TE412P supports a 3.3v PCI slot only - typically available on newer motherboards and in 64-bit PCI bus architectures
