MT90826AL1

Introduction

MT90826AL1 is a Line/Trunk Interface Solution that supports Transparent and Robbed-bit Signaling Protocols. The device combines an efficient DAA, DC-DC converter, ringing generator, and other associated Call Processing circuits. The current MT90826AL1 supports an integrated DAA solution and has improved many performance levels.

Application Field

MT90826AL1 is mainly used in VoIP communication networks and VoIP phone systems. The device combines an efficient DAA, DC-DC converter, ringing generator, and other associated Call Processing circuits, and provides various interface solutions to various external networks. The device also supports various applications in residential and SOHO VoIP phone systems because of its ultra-low power consumption, low EMI and fast startup features.

Work Principle

The MT90826AL1 device works by converting an analog telephone line connection to an ISDN-like digital signal. By doing this conversion, it is possible to use existing analog telephone lines to connect directly to a VoIP phone system or other IP PBX without the need for additional hardware. The device is also capable of providing VoIP phone systems with greater functionality such as bridging, call forwarding, and other features. The MT90826AL1 is designed to manage the signaling from the phone system and to convert it into a format which can be read by the VoIP server. The signaling is transmitted using a critical interface. The interface used is either the CAPI or SIP protocol, which are both industry-standard protocols for communication between a VoIP phone system and the server. In a typical installation, the equipments necessary for the device to work properly include: - Telephone line - A standard analog telephone line with a RJ11 plug must be connected to the device. - IP network device - An IP network device (e.g. ADSL modem) should be connected to the device to provide a connection to the internet. Once the required equipment is in place, the device will then begin to monitor the telephone line and detect if there is an incoming call. When this happens, it will then initiate the necessary signaling to establish the connection with the VoIP server. Once the connections have been successfully established, the device will then act as a gateway between the telephone line and the VoIP server in order to transfer communication data between both.

Conclusion

The MT90826AL1 is an effective and easy to use Line/Trunk Interface Solution that supports Transparent and Robbed-bit Signaling Protocols. It is an ideal device to bridge the gap between analog and digital telephony systems. The device is very easy to set up, and provides a wide range of features and performance levels at an affordable price.
