Application
Industrial G.SHDSL.bis EFM/TDM Modem – E1/V.24/V.35/Ethernet
TAINET’s Comet 1654/1644 series, is so called Ethernet Access Devices (EAD), Ethernet Media Data Converter (MDC), Ethernet Multiplexer (EMUX) or Ethernet DSL modem, which takes advantage of the latest G.SHDSL.bis standard, is a mini-terminal enabling the transport of traffic from Ethernet, E1, Nx64k Data and RS-232 interface with line rate 15M/30Mbps over 4 wires G.SHDSL.bis link.
Comet 1654/1644 series supports high-speed dedicated symmetrical data transmission and utilizes DSL bandwidth. When data rate is within 2Mbps, the transmission distance can reach 6km. When the transmission distance is within 3km, the data rate may over 4Mbps.
Comet 1654/1644 series is a perfect solution for Telecom Carriers, Service Providers and business users. To reduce operation/ management burden, Comet 1654/1644 series can control and monitor remote unit via Embedded Operation Channel (EOC) by following ITU-T G.991.2 standard. Not only manage by local console and DIP-Switch operation, but also can remotely configure them via Telnet/ SSH, Web/ HTTP/ HTTPS or through SNMP agent.
