The SPOCS software predicts the performance of xDSL systems (expressed as maximum bitrate, noise margin or reach) for the defined scenario, which comprises, among other things, the xDSL system type (ADSL, ADSL2+, SDSL, VDSL2, etc), the cable type, and the number or type of existing or supposed disturbers in the same cable. SPOCS outcomes can be used as input for a business case, to formulate a roll-out strategy, or to define spectrum access rules. You can use SPOCS to assess the impact of VDSL2 on ADSL2+ and modify VDSL2 (PSD shaping) in order to achieve the optimum commercial scenario. SPOCS provides the necessary insight into xDSL systems.

The Network Strategy Manager at a large incumbent operator had this to say about SPOCS: 'SPOCS was the missing tool that our organisation needed in order to create an optimum VDSL2 roll-out strategy'.

Applications

• SPOCS - a solution for performance prediction
  SPOCS can predict the performance of xDSL systems under various noise conditions, including impairment from a large number of neighbouring xDSL systems at random locations, as well as loss and crosstalk coupling in different cable types of various lengths.
• SPOCS - a solution for performance testing
  SPOCS has an optional functionality, namely a profiler that allows the user to export a PSD shape and upload it to a noise generator. In other words, SPOCS can specify a noise profile for a noise generator as part of a test set-up, for example to assess the performance of a modem.

Availability

SPOCS enables the user to predict the performance and impact of xDSL systems in almost any desired scenario (e.g. the impact of VDSL2 on ADSL2+ including PSD shaping).
