How is a DSL filter used with a digital mailing system

UPDATED: 15 June 2015

DSL (Digital Subscriber Line) is a digital line that is provided by telephone companies to local subscribers:

  • DSL provides digital data transmission over the wires of a local telephone network. It can be used at the same time and on the same telephone network with regular telephone (POTS), as it carries data at high speeds, using high frequency bands, while regular telephone uses low frequency.
  • Due to the high frequency bands, postage meters cannot communicate on DSL lines without the use of a filter
  • DSL filters are adapters that are used to shield a phone line from the digital noise and interference caused by telephone devices.
  • You can purchase a DSL filter from any office supply store or sometimes, the phone company can provide one for little or no cost. An example of a DSL filter is provided for reference.

Installing a DSL Filter:

  1. Unplug the regular phone cord from the wall jack
  2. Plug the DSL filter into the jack
  3. Now plug the phone cord into the DSL filter
