    RoHS Compliant
The Loop-H3308-R plug-in card provides high speed digital transport for Ethernet and point to point
applications. The rack card converts Ethernet ports over multiple twisted copper pairs by using the
16-TCPAM, 32-TCPAM (G.SHDSL.bis) technology and the IEEE 802.3ah 2Base-TL bonding protocol. There
are 2, 4 or 8 pairs configuration for the G.SHDSL.bis interface. The total bonded bandwidth is dependant on
the number of copper wires.

The Loop-H3308R works as a pair (as master and slave). The slave unit is usually located at the customer's
premises. The distance that this technology can span without repeaters is dependent on the data rate. The
Loop-H3308R supports configuration and diagnostics by using a local terminal or a remote Telnet or SNMP
manager. This allows execution of diagnostics and fault isolation.

The bonding method ensures line cut resilience by removing failed pair(s) from an aggregation group within
50ms. This removal decreases service bandwidth. When the failed pair(s) has recovered, the aggregation
bandwidth will become normal without disrupting the service. For user maintenance, the Bonding
G.SHDSL.bis system supports manual addition or removal of pair(s) without disrupting the service bandwidth
of the remaining pair(s).G. SHDSL.bis supports different line rates. The ratio between the highest and lowest
line rates can be up to 4:1.
