Brand Name	CircLoop

Introduction

TL300 series products are Network adaptor developed by Beijing CircLoop Digital Image Tech. Co., Ltd. independently, which can extract SIP from TS and parse it, and adjust the output bit rate of ASI TS automatically to ensure the signal of SFN can be transmitted transparently, synchronize the signal transmitted by all transmitters in the DVT-T SFN. TPS signal command support all mode of GB20600-2006, it is indispensable equipment to construct DTV-T SFN.  

Network of DS3/E3 to ASI and E1×4 to ASI are available, support transmission that SFN signal on the telecommunication equipment of microwave SDH etc. it is convenience to construct SFN network. This series equipment can combine with our products TL400 seriesIP600IR600 etc to make many kind of SFN transmission scheme. 

This series equipment can be used as network adaptor which convert DS3 to ASI and E1×4 to.

This series equipment has abundant input and out put interface. With one channel DS3/E3 input interface, it can support SFN sip extracting. It has GPS clock input interface, one channel 10MHz input interface, E1×N input interface N=1234, DS3/E3 output interface, 2 channel ASI-A output interface, two channel ASI-B output interface.

It is modular and plug-in plate structure. Based on the web browser management and controlling, it is easy to operate and maintain.
