Product Name: Voice Slic for 3G GSM Fct Model NO.: A310S Condition: New Certification: ISO Information content: Voice Support Network: GSM Type: Wireless Usage: Telephone, Computer, Server, Laptop Trademark: OEM Transport Package: Carton Specification: 13.5mm*76.6mm Origin: China HS Code: 8501109190 Product Description A310Sis a standard multi-functionsliccircuit module, which adopts 9sip single in-line pin, saving occupied area, low cost, convenient for designers to quickly provide slics to meet market demand. The designed output loop length of xzxm100 can reach 3km, which can adapt to public network and application. A310Sis internally integrated with DC/DC conversion circuit, ring generation circuit, incoming signal generation function and polarity reverse function. There are few peripheral components. This slicis suitable for various applications of short subscriber line, such as ISDN terminal adapter, VoIP, computer integrated telephone, Wll and SOHO.Slic functional characteristics:1. Low power consumption, sip-12 package; 2.Built in DC-DC circuit, output tip, ring terminal voltage 48V, low inputvoltage 5.0V; 3.Built in ring generation circuit; 4.Built in tip/ring polarity reversal function, which can be used to generatethe leading or billing signal of caller ID signal; 5.Programmable line impedance (enhanced function); 6.Easy to use, few external components; 7.Built in MCU processing, using UART (9600, 8n1) control mode; 8. Various practical functions can be completed through UART interface: *Control to generate the caller number output of FSK/DTMF system; *Control to generate 25Hz ringing signal; *Collect and output the dialing number; *Control and output DTMF/FSK signal of any format; *Off hook/on hook detection and output; *Reverse polarity signal generation; *Dial tone/busy tone and other signal tone output.Slic technical parameter:Appearance dimension:13.5mm*76.6mmPad spacing is:2.54mmSlic interface:Pin description:1.Ring (b) tip.
