MT8870DE1-1

The MT8870DE1-1 is an advanced low power dual echo canceller designed to serve a variety of applications, such as VoIP, ISDN, PSTN, Fax, Video Conferencing, etc. The device integrates two echo cancellers and associated filters, allowing customers to maximize their system potential and minimize system cost. Its features and functions make it an ideal solution for developing cost-effective applications.

The MT8870DE1-1 can be used in two-stage or two-wire communications. In two-stage communication, the device transmits and receives audio information, as well as echo cancels the signal path. On the other hand, in two-wire communications, the device transmits audio information and only echo cancels the return path signal. Both of these applications operate in tandem for optimal system performance.

The primary purpose of the MT8870DE1-1 is to reduce or eliminate the echo effects that are often present in a two-wire telephone line. This is accomplished by using two internal echo cancellers, which are designed to cancel any incoming echoes before they reach the user. Each echo canceller is designed to adjust automatically to the characteristics of the telephone line, in order to optimize the echo cancellation performance.

The MT8870DE1-1 also includes programmable DTMF and Tone filters which are used for detection, digit recognition, and tone generation. These filters provide precise detection of both DTMF and Tone signals, eliminating any false positive signals. In addition, the device includes additional interfaces for external remote control, as well as status monitoring.

One of the primary applications of the MT8870DE1-1 is in Voice Over IP (VoIP) systems. This type of system requires two independent echo cancellers, in order to efficiently cancel both directions of the conversation. The device is capable of providing this type of performance, as it has two independent echo cancellers, as well as two digital and analog filters.

In addition, the MT8870DE1-1 is also well suited for ISDN applications. In this type of system, the device serves as a bridge between the analog and digital line signals, allowing for efficient communication between two parties. The device also includes extra digital and analog filters to help reduce the amount of noise that can be present on the line.

Finally, the MT8870DE1-1 is a great solution for PSTN and Fax applications. It is able to detect any incoming call and identify the type of call, allowing for a custom configuration to be applied. Furthermore, it is able to detect when a fax is being sent, and can apply suitable tone and digit recognition filters to ensure that the fax is transmitted without any errors.

In conclusion, the MT8870DE1-1 is an ideal solution for a variety of applications, such as VoIP, ISDN, PSTN, Fax, and Video Conferencing. Its advanced features and functions make it a great choice for customers who are looking to maximize their system potential while minimizing their system cost.
