Powerlink 844


SHDSL digital modem which allows data communication through multiple channels, data rates (multi-rate) and interfaces (multi-interface) over leased lines.

Powerlink 844 is offered in 6 distinct versions. Depending on the version, it can operate as 4 independent modems over 2 wires, as two independent modems over 4 wires, or as a single modem over 8 wires, with rates that may range from 64 Kbps to 16384 Kbps configurable at steps of 64 Kbps. Such versatility provides high performance as much in terms of speed as of reach.

It allows operation according to three distinct digital interfaces combinations, thus granting customers with greater flexibility. It can provide four G.703 interfaces, or one G.703 interface and one Ethernet interface, or a single Ethernet interface.
