Overview

The Paradyne proprietary Synchronous Data Compression (SDC) feature allows an increase of throughput in data transmission, and has an error correcting procedure so that transmitted data is less sensitive to channel disturbances.

The ITU-T recommendations V.42bis and V.42 have data compression and error correcting (EC) procedures for DCEs connected to asynchronous DTEs. These procedures form the basis of Paradyne's SDC feature.

With the SDC feature, two DTEs can exchange data via a synchronous protocol (Figure 1) while the DCE provides the new synchronous data compression and error correction functions (Figure 2). The synchronous data from the local DTE, after compression, is inserted into DCE frames which are sent to the remote DCE. Inverse operations then occur at the remote DCE.

SDC can be used with V.34 and V.32 family modulations on dial or leased lines, and in a dial backup or standby mode.

SDC is available as an installable option beginning with firmware Release 3.0.
