More info

The EyeSDN USB-A8Bx is a call recording device for eight analogue phone lines or eight audio signals. The lines are passively tapped with a high impedance circuit. The device performs DC voltage measurements to detect line states like on-hook, off-hook or ringing.

The audio data and voltage information is transferred to the PC via a USB cable, which is also used to power the device. Software on the PC uses the line voltage information and audio samples to detect active calls. The device can obtain caller ID information using DTMF or V.23 modem data and decodes DTMF or pulse dialing. The presence of a call can be detected by either analysing line voltage variations or by identifying speech activity.

The EyeSDN USB-A8Bx has 16 multi-colour status LEDs which indicate;

  • device activity,
  • the line power state,
  • the line ring state,
  • on-hook/off-hook state,
  • and the presence of caller ID.

The small form factor and rugged enclosure make EyeSDN USB-A8Bx suitable for stationary and mobile use. Two threaded holes at the bottom of the unit allow mounting of the device to a chassis or into a rack.
