Figure 5-2 Recorder adapter

The recorder adapter has an interface for a second headset and a recorder interface.

The way in which the headset plus adapter interacts with the telephone and the CS is described by the CorNet-TS layer 3 specification for Symphony. The CS can detect a second headset af- ter it has been plugged into this option.

Interface Description

When a second handset is connected, the uplink beep capability is provided by adding the beep and uplink audio during the beep. A beep detection circuit activates the uplink beep when the switch recorder generates the beep signal, thus maximizing the echo reflection attenuation. The users hear the uplink beep in the secondary tone path.
