An accessory interface bus for a telecommunications headset adapter or base unit, which controls and monitors the operations of various headset accessories coupled to the interface bus, is disclosed. The accessory interface bus allows the telecommunications headset adapter to detect when a new accessory is coupled to the bus. The interface bus may be implemented within a headset adapter base in a telecommunications system that includes the headset adapter base, a telecommunications headset coupled to the adapter base, and various headset accessories coupled to the adapter base. The interface bus transmits control and status signals between the headset adapter base and the various headset accessories to directly control and monitor operations for each headset accessory coupled to the interface bus. The control and monitoring of a given headset accessory may include activating or deactivating, resetting, and/or simulating a button press of a button located on the accessory.

Accessory interface bus for telephone headset adapter

A headset having a built-in memory to store parameter settings relating to headset performance characteristics such as headphone(s) and/or microphone performance characteristics. The performance characteristics can be measured during headset production and stored in the memory. A host adapter may communicate with the headset through a serial communications port of the headset. The host adapter may read the headset performance characteristics and adjust signals transmitted to and received from the headset in accordance thereto. When the headset is used in a system, the system parameters can be manually set and stored in the headset memory. When the headset is used again in the same system, the system parameters can be read from the memory and automatically set. The memory may also store product history information of the headset such as production date, serial and model numbers, and/or any service history.
