Quad Span T1/E1 volt with echo cancellation octasys module The TE420B is the next generation of Digium hardware that improves performance and scalability through bus mastering architecture. The TE420B supports both E1 and T1/J1 environments and is selectable on a per-card or per-port basis. This feature enables signaling translation between E1 and T1/J1 equipment and allows inexpensive T1/J1 channel banks to connect with E1 circuits. Because the TE420B improves I/O speed over slave-only architecture, the result is reduced CPU usage and increased card density per server.
The TE420B 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 TE420B is for use only with a 5.0-volt or 3.3 volt PCI Express slot. Data Modes: Cisco HDLC HDLC PPP Multilink PPP Frame Relay Voice Modes: PRI CPE & PRI NET NI1 NI2 EuroISDN 4ESS (AT&T) 5ESS (Lucent) DMS100 E&M Wink Feature Group B Feature Group D FXO & FXS Ground Start Loop Start Loop Start with Disconnect Detect Digium has designed the TE420B to be fully compatible with existing software applications and it is fully integrated with the Asterisk Open Source PBX/IVR platform. Also, the open source driver supports an API interface for custom application development. With the combination of Digium Hardware and Asterisk software, numerous combinations of telephony configurations are possible.
