About Digium

Profile

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.

About Asterisk

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:

1. Octasic based on DSP (all modules)
2. 128 ms (1024 taps) of Cancellation of Echo through all the channels
3. G.168 of Quality of AT & T certified number that complies with algorithm
4. Non-linear Dynamic processor
5. Noise comfort generator
6. Automatic Row Search
7. Cancel Multiple Reflections
8. Double dialogue detection

Digium Modulo VPM435

Para los usuarios de Asterisk que se conectan a la red RTC (PSTN), el tipo más común de eco es el eco híbrido:  el eco introducido por la falta de concordancia entre los circuitos telefónicos de 2 hilos y 4 hilos. El eco se manifiesta como un reflejo distorsionado y retrasado de la voz del usuario, en una conversación con una parte externa a través de la RTC (PSTN).
Asterisk ofrece una serie de rutinas basadas en software de código abierto de cancelación de eco que son moderadamente efectivos para eliminar el desajuste del eco híbrido que experimenta la mayoría de usuarios RTC (PSTN) (a cargo de los recursos de la CPU).

Sin embargo, hay casos en los que estos algoritmos no son eficaces. Para combatir esto, Digium presentó módulos de cancelación de eco hardware basados en DSP, para los distintas tarjetas telefónicas de múltiples puertos Digitales y Analógicos

For Asterisk users connecting to the PSTN, echo with the voice communication is possible and can be managed effectively with echo cancellation modules from Digium. Asterisk has a range of software-based Open Source echo cancellation routines that are moderately effective in eliminating the echo that most Asterisk users experience. However, there are cases in which these algorithms are not effective. To combat this, Digium offers a line of DSP-based echo cancellation modules for all the Digium analog and digital (T1/E1/J1) cards with the VPMOCT series modules.

The BRI power supply (SPEC-BNPWR1) is a power supply unit that is used to power BRI phones or other BRI devices connected to our BRI card. This is only for the BRI card in NT mode with TE devices connected to it. When the Sangoma card is in TE mode this device should not be used. 

The power supply unit is powered with a molex connector (from internal/external PSU), the output of the unit will be a connector that will plug into the green connector on the Sangoma card. See image below for the location and picture of the green connector. 

The beroNet Bridge (bfBridge) can be used to access all 4 RJ45 outputs of a berofix baseboard with only one bf4S0,bf4FXS,bf4FXO or bf2S02FXS plugged on the baseboard.
