description  
The TNETEL1400 is an Etherloop transceiver. EtherLoop technology enables simultaneous voice and Ethernet  
communication over local-loop plain old telephone service (POTS) wiring. The TNETEL1400 supports data  
rates of up to 6 Mbit/s and POTS wire lengths of up to 21,000 feet. Figure 1 shows a typical system with an  
EtherLoop modem located at each end of the POTS line. Each EtherLoop modem has a 10Base-T Ethernet  
interface and is responsible for buffering Ethernet data before sending it over the POTS wire. The server-end  
(SE) EtherLoop modem is located in a central switching office and can communicate with several client-end  
(CE) EtherLoop modems, based on a round-robin arbitration scheme. The CE EtherLoop modem typically is  
located at a remote site.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
