  • Page 2 Description The Inline Patch gives you access to the audio from both sides of your telephone call. Simply install this little box “inline” between the telephone wall jack and the base of your telephone. You can use any single-line residential (analog) corded or cordless telephone or if available the data / modem port on a digital or PBX telephone.

  • Page 4 Setup for use with PBX phone systems is the same as analog telephones with one exception. Instead of connecting the phone line jack of the Inline Patch to a wall jack, you will connect to the data / modem jack of your PBX phone. You will still need a regular analog telephone connected to the phone jack of the inline patch.

The 3.5 mm “stereo” jack has the phone line audio on the left channel and your voice on the right channel. The second 3.5 mm jack has both sides of the call combined on both left and right channels.
  • Page 6 Operating (continued) The hybrid circuitry in the Inline Patch can provide a nominal 20 dB of transmit / receive isolation. When using the stereo jack with stereo speakers, the 20 dB isolation will give you substantial left / right separation. The separation on FM stereo is typically around 20 dB.
