Based on SHDSL technology, it allows existing copper cables to be used to create Ethernet IP-based networks for significant time and cost savings. Should a unit suffer a power failure, the line extender’s integrated bypass relay short-circuits the two SHDSL interfaces, allowing a renegotiation between adjacent extenders so communication can be restored automatically. The unit also provides power failure resiliency, ensuring continued network operation in the event of a primary power failure. A dual power supply is now complimented by a 12 VDC option, which enables a battery to provide the power supply redundancy. The transition between primary and secondary power is immediate and seamless, ensuring maximum network uptime. The unit allows networks to be created over distances of up to 15 km, offering data rates of over 15 Mbps on a single twisted pair cable. Bonded pairs double this rate to over 30 Mbps. An integral switch enables two Ethernet devices to be attached and a further RS-232 port ensures legacy equipment can be incorporated into an IP network. Installation requires no configuration for basic applications and a web interface supports simple configuration for more complex networks.
