The Loop-H3308 is a standalone device which provides high speed digital transport for Ethernet, V.35 and RS232 point to point applications. The device converts Ethernet, V.35 and RS232 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 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-H3308 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 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. |
