For Asterisk users who connect to the PSTN, the most common type of echo is hybrid echo - the echo introduced by the impedance mismatch between 2-wire and 4-wire telephone circuits. The echo manifests as a distorted and delayed reflection of the users voice while in conversation with an external party through the PSTN. Asterisk itself offers a range of software-based open source echo cancellation routines that are moderately effective in eliminating the hybrid mismatch echo that most Asterisk users experience.
However, there are cases in which these algorithms are not effective. To combat this, Digium introduced DSP-based echo cancellation modules for our multi-port T1/E1/J1 cards and our 24-port analog card.
Digium®, Inc., the Asterisk® Company, created and is the innovative force behind Asterisk, the most widely used open source telephony software. Since its founding in 1999 by Mark Spencer, Digium has become the open source alternative to proprietary communication providers, with offerings that cost as much as 80 percent less. Digium offers Asterisk software free to the open source community and offers Switchvox, Digium's Unified Communications solution to power a broad family of products for small, medium and large businesses. The company's product line includes a wide range of telephony hardware and software to enable resellers and customers to implement turnkey VoIP systems or to design their own custom communications solutions. At Digium, we're changing the way businesses communicate.
Asterisk is the world's most popular open source telephony project. Under development since 1999, Asterisk is free, open source software that turns an ordinary computer into a feature-rich voice communications server. Asterisk makes it simple to create and deploy a wide range of telephony applications and services.
Code for Asterisk, originally written by founder and CTO, Mark Spencer of Digium, Inc., has been contributed from open source software engineers around the world. Currently boasting over two million users, Asterisk supports a wide range of TDM protocols for the handling and transmission of voice over traditional telephony interfaces, featuring VoIP packet protocols such as SIP and IAX among others. It supports U.S. and European standard signaling types used in business phone systems, allowing it to bridge between next-generation voice-data integrated networks and existing infrastructure.
The Digium cards in the TE series are high performance, cost effective, with digital telephone interfaces that support the T1 and E1 environments. The environments are selectable on a base ny card or by port. This characteristic allows the translation of the signaling between the equipment T1 and E1, and allows to connect banks of economic channels T1 with circuits E1.
Sometimes it may happen that your IP communications systemn is echoed, this can happen as a result of the waiting times that a VoIP system often has, unlike an analog system. As a result, your conversation may suffer an echo.
Although many devices already incorporate the echo canceller, Digium offers the Digium High Performance Echo Cancellation (HPEC) hardware. Echo cancellation hardware is also advantageous when handling large volumes of calls or high numbers of channels that would otherwise strain the CPU which would result in poor audio potential quality. Here are some of its features:
The FX0 module allows the TDM400P card to termiante analog telephone lines (POTS). Because of the modular design, a user can activate additional ports at any time with more FXS or FX0 daughter cards.
The FX0 module passes all the call features any standard analog telelphone line will support.
• TDM410P (hasta 4 módulos)
• TDM800P (hasta 4 módulos)
• AEX410P (hasta 4 módulos)
• AEX800P (hasta 4 módulos)
• HA8 (hasta 4 módulos)
• HB8 (hasta 4 módulos)
The FXS module allows the TDM400P card to terminate analog telephones. Because of the modular design, a user can activate additional ports at any time with more FXS or FX0 daughter cards.
The FXS module passes all the call features any standard analog telelphone will support.
The B400M sets a new standard for BRI connectivity in the Asterisk market with its support for software-selectable mode (NT or TE) and line termination. The B400M requires no jumpers for operation, regardless of mode or termination.

Now, Digium is pleased to make available the VPMOCT032 echo cancellation module. This module, which offers 128ms (1024 taps) of echo cancellation across all of its channels and provides the same toll-quality G.168 compliant echo cancellation found in Digium's HPEC software-based commercial echo canceller. The VPMOCT032 is immune from any system CPU spikes that might otherwise affect a software-based solution.
Módulo Cancelación de Eco Hardware basado en DSP, proporciona el algoritmo G.168 que ha marcado un punto de referencia para la cancelación de eco y realiza 128ms (1024 taps) de cancelación de eco en TODOS los 120 canales del modo primarios E.
• Hasta 128 canales.
• 128ms (1024 taps) por canal.
Este módulo trabaja con las siguientes tarjetas:
• TE410P (bundled como TE412P)
• TE405P (bundled como TE407P)
• TE420 (bundled como TE420B)
The bf4S0 Lineinterface is a 4 port BRI / ISDN module for berofix product series. Each port of the bf4S0 Lineinterfaces can thereby be configured as NT (Network Termination) or TE (Terminal Equipment). In both modes, each port can operate in Point-to-multi-point (PMP) or in Point-to Point (PTP) mode. The switching of the TE / NT mode and the switch off the termination resistors can easily be set in software (JumperFree) twhich makes the troublesome reposition jumpers unnecessary.

El bf2E1 es módulo de dos PRI (1E1=30 lineas) de RDSI para las tarjetas berofix. Puede ser configurado individualmente por puerto a NT/TE (es posible que necesite un cable cruzado opcional disponible ("bnE1Crosscable"). Terminación de línea (120/75 ohmios) seleccionable para cada puerto.
• 2 puertos PRI/E1
• Cada puerto puede ser configurado individualmente modo TE/NT.
