DTV Network Adapter (TL300, TL400)

Product Description

TL300 Network SFN Adapter

Introduction
TL300 series products are Network adapter developed by Beijing CircLoop Digital Image Tech. Co., Ltd. Independently, which can convert DS3/E3 to ASI or E1× 4 to ASI, and support SFN signal's transmission.
This equipment can ensure SIP's SFN signal is transparently transmitted on Telecom equipment such as microwave and SDH etc. Support all 33 modes of GB20600-2006. This series equipment can join with our products IP600\IR600\ TL400 series etc to make many kind of SFN transmission scheme.
This series equipment can be used as network adapter which converts DS3 to ASI and E1× 4 to ASI.
This series equipment has abundant input and output interface. It has 1 channel DS3/E3 input (with active loop output), GPS clock input(10MHz\1PPS), E1× N input (N=1\2\3\4), 2 channels ASI-A output, 2 channels ASI-B output.
It is modular and plug-in plate structure. Based on the web browser management and controlling, it is easy to operate and maintain.

TL400 Network SFN Adapter
Introduction
TL400 series SFN Adapter is new generation DTV network adapter developed by Beijing CircLoop Digital Image Tech. Co., Ltd. Independently, it integrates the "SFN network adapter" and "SFN transmission adapter" into one equipment. It has been approved by State Administration of Radio Film and Television, and got Certificate of Accesses Network of , the Number is 011100505199.
This equipment can generate and insert SIP into the TS periodically, and adjust the bite rate of TS automatically according to the 33 models of GB20600-2006, make signal transmitted by territory DTV SFN keep synchronized.
From ASI to DS3/E3 and E1x4 network transmission adapters are available, support SFN signal Transparence Transmission on telecommunication equipment of microwave and SDH and so on, It can be used together with our IP600\ IR600\ TL300 network adapter etc to form multiple types DTV-T SFN signal transmission scheme, It is convenience to construct SFN, .
It also can be used as network adapter of ASI to DS3/E3 or E1× 4.
With abundant input and output: ASI input which includes main and standby input and can switch automatically, two ASI output, GPS clock input (10MHz\1PPS), E1xN input interface (N=1, 2, , 3, 4); 2 channels DS3 output.
It is modular structure and plug-in plate structure, based on web browser management, and easy to operate maintain.
