description
NU – Not used
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.
