WHAT IS IT? Data Access Radial (W-DAR) is one of the data communications services from TelstraClear Wholesale’s portfolio of Narrowband Private Leased Circuit Services. These Layer 1, Time Division Multiplexed (TDM) circuit switched services provide reliable and secure data transport over a dedicated communications channel. W-DAR can be used to provide the underlying access network over which you can build and deliver an end-to-end service for your customers.
WHAT DOES IT DO?
The W-DAR service can provide either a dedicated point to point (W-DAR-S) or point to multipoint (W-DAR-M) access service depending on the A end access type chosen.
With the standard A end access option W-DAR provides a single point-to-point N x 64kbit/s connection between A end and B end (i.e. 64kbit/s up to 1984kbit/s).
With the aggregated A end option W-DAR enables a number of discrete Nx64k connections (i.e. 64kbit/s up to 1984kbit/s) from many different end customer (B-end) locations to be aggregated and delivered as contiguous timeslot bundles on a single 2Mbit/s link between your A-end Point of Presence (POP) and the nearest TelstraClear Digital Cross Connect switch (DCC or DAC’s). With the aggregated A end option the 2Mbit/s aggregate link is referred to as the W-DAR Primary circuit. The circuits from B-end locations that are delivered into the A-end over the primary circuit are referred to as secondary circuits. By using W-DAR in conjunction with your own POP infrastructure you can provision your own carriage services e.g. Dedicated Data, Frame Relay and Internet Access services.
