TAINET’s SNTU 765 series is a DSL line card that enables the Ethernet & E1 data to be transmitted with the speed of 5.7/11.4Mbps over 2/4 wires. It supports up to 15 Mbps per pair of G.SHDSL.bis symmetrical data transmission under extension mode.
SNTU series is compatible with the TAINET iEAC-16 chassis. This combination is designed to work as a central office especially for long-distance Ethernet Access Service. To reduce the burden of operation/management the operator can control and monitor the remote unit via Embedded Operation Channel (EOC) by following ITU-T G.991.2.Moreover, the administrators can also easily configure all Comet series through Telnet (SSH), Web HTTP/HTTPS) or SNMP agent.
