Product Description

SIP AUDIO MODULE SIP2703T

SIP2703T network audio module is a general independent SIP audio function module, which can be easily embedded into OEM products. The module encodes and decodes SIP protocol and RTP audio stream from the network.

The module supports a variety of network protocols and audio codec protocols, and can be used for VoIP and IP paging, high-quality
music streaming media playback and other applications

SIP2703T also provides two serial ports and eight digital I / O, allowing users to control through programs.

Characteristic

Standard RJ45 network interface, provide firmware online remote upgrade;

Based on ARM + DSP architecture, high-speed industrial chip is adopted, and the start-up time is less than 1 second;

Multiple IO interfaces are provided to enrich the module functions;

It has the function of controlling the serial port and can control the work of the module;

It has the function of universal serial port and can realize the function of transparent data transmission;

It has audio line output port, which can be connected with active speaker for amplifying;

With audio line input port, it can be connected with active microphone for intercom.

Structure

SIP2703T uses an ARM processor architecture with a speed of up to 400MHz plus a professional two-way audio Codec codec. The ARM processor is responsible for data transmission, user command analysis and execution, and control of the power amplifier interface. Professional audio Codec is responsible for audio input and Output. Its internal structure is as follows:

Its appearance structure is as follows:

Application

Outdoor loudspeaker

Desktop walkie talkie

intercom terminal

PLAY

The network audio equipment can receive the audio stream from the network, and convert it into an analog audio signal for output after being decoded. The figure below is a standard playback application scenario.

The SIP2701T/SIP2703T network audio module is used as a playback terminal, and only needs to increase the power supply and external power amplifier. It can be used as a device alone, or integrated in other audio equipment (power amplifier, or active speakers, etc.) to make it a network audio playback terminal.

INTERCOM

SIP2703T can be used in a two-way SIP intercom system

The broadcast intercom host can use our company's broadcast system control software, broadcast equipment, network microphones, etc., or use the SIP server prepared by the user.

This VoIP Telephone Circuit is ideal for access system, railway applications, tunnels, highways, campus, parking lot, power stations, oil&gas station, marine applications, underground mining, retail banking, clean rooms, firefighter, taxi, industrial, prisons, parking-lots, power stations, chemical plants, etc.
