Product Description
SIP audio module SIP2101T
SIP2101T network audio module is a general-purpose independent SIP audio function module, which can be easily embedded into OEM products.
This module encodes and decodes SIP protocol and RTP audio streams 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.
feature
Standard RJ45 network interface, providing online remote firmware upgrade;
Based on ARM+DSP architecture, using high-speed industrial-grade chips, the startup time is less than 1 second;
With an audio line output port, it can be connected to active speakers for amplification;
With an audio line input port, an external active microphone can be connected for intercom.

structure
SIP2101TAdopt 400MHz ARM processor architecture and professional two-way audio codec. The arm processor is responsible for data transmission, user instruction analysis and execution, and power amplifier interface control.
A professional audio codec is responsible for audio input and output. Its internal structure is as follows:
Its appearance structure is as follows:
application
PlayNetwork audio equipment can receive audio streams from the network, decode them and convert them into analog audio signals for output. The figure below is a standard playback application scenario.
SIP2101T/SIP2103T network audio module is used as a playback terminal, only need to add power supply and external power amplifier. It can be used alone as a device, or it can be integrated with other audio devices (power amplifiers, active speakers, etc.) to become a network audio playback terminal.
walkie talkieSIP2103T can be used in 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 systems, railway applications, tunnels, highways, campuses, parking lots, power stations, oil and gas stations, marine applications, underground mining, retail banking, clean rooms, firefighters, taxis, industrial , prisons, parking lots-lots, power stations, chemical plants, etc.
