Brief Introduction
PT-20 ETH HDSL Equipment will execute the Ethernet signal transmission in the local cable or military twisted cable. It adopts G.SHDSL standard. G.SHDSL is one type of symmetrical, multi-rate DSL. It accords with ITU-T standard (G.991.2), and it is the ideal equipment to do the terminal to terminal solution. It has the advantages of rate-adjustment technology and grid coding pulse amplitude modulation (TC-PAM). G.SHDSL selects TC-PAM as its modulation technology, which is fully accepted by the customers because it can save copper cable and be based on multiple standards. Compared with 2B1Q SDSL, TC-PAM frequency spectrum is narrower, and crosstalk interference will be less.
Main Features
* Adopting the new generation TC-PAM technology, which satisfies ITU G.992.1 international standards, its performance is better than that of 2B1Q coding, the circuit enjoys high integration, small size, low power consumption, and high reliability;
* Transmitting cable: twisted pair cable;
* Long transmitting distance, when the transmitting speed is 2048kbps, the transmission distance can reach 3.5km in 0.4mm cable;
* Communication mode: duplex, echo canceling;
* Easy to install and use, and also has the functions of parameters setting and management for remote equipment;
* Power supply: 220VAC.
