DPX-650 MUX

The DPX 650 reduces data transmission costs associated with low speed leased telephone lines. In many telcos leasedline costs are heavily dependent on the distance between source and destination telephone exchanges (and the number of inter-exchange trunks utilised).

A true Time Division Multiplexer, the DPX-650 allows data from several sites in a local telephone area to be collected onto a single higher speed line and sent to a distant computer site where it is demultiplexed into the original channel order.

The product is suitable for any network utilising low speed asynchronous data lines for telemetry or control. It is especially cost effective for situations where the computer hub is distant from a cluster of geographically grouped series of sites with which it must communicate.

It is ideally suited to the Sydney Co-Ordinated Adaptive Traffic System (SCATS) in handling communications from several traffic control intersection sites in an area remote from the Regional Computer which controls it.

Rather than run several expensive long lines direct from each site to the regional computer, lines are collected in their local Telstra exchange area at minimum line charge, and multiplexed onto a higher speed line for transmission to the distant computer.
