Base to phone connecting cable for CS50, AWH55+, AWH55 & AWH54

  • Connects Plantronics CS50 or discontinued Avaya AWH55+ wireless headset base to phone
  • 36″ in length, flat black cord
  • Has in-line filters which causes a noticeable bump on both ends of the cord (as pictured)
  • Clear modular 4 wire connection on each end of the cord
  • It is not recommended to use any other connection cord in place of this cord on a CS50 or Avaya AWH55+ because a cord without the built in filter has a good chance of a buzz occuring in either the headset or handset (this is a 900 MHz issue)
  • Genuine Plantronics accessory
