SNTU 765 Series

Ethernet/E1 over G.SHDSL.bis Converter

The SNTU765 series which takes advantage of the latest G.SHDSL.bis standard, is a mini-terminal enabling the transport of traffic from Ethernet and E1 interface with speed 5.7M/11.4M over EFM bonded 2/4 wires G.SHDSL.bis link. 

The SNTU765C supports high-speed dedicated symmetrical data transmission and utilizes DSL bandwidth. The automatic line rate can be up to 5.7Mbps over 2-wire copper line. To reduce operation/management burden, SNTU765C within iEAC-16 can control and monitor remote unit via Embedded Operation Channel (EOC) by following ITU-T G.991.2. 

  • SNTU765 is a line card type for iEAC-16. For standalone model, please refer to Comet 1630
