The methods for installing a DSP card and voice daughter card in different router models are the same. The following procedure installs a DSP card and voice daughter card in an AR2204 router.

Tools

  • ESD wrist strap
  • Phillips screwdriver
  • Hex socket wrench
  • Voice daughter card (optional part)
