Abstract
The arrangement is for coupling optional additional equipment to terminal equipment of private branch exchanges via an additional equipment interface, particularly according to the ETSI standard. The terminal equipment has an option bus via which arbitrary additional equipment can be connected. An additional equipment driver specific to the additional equipment and that represents the additional equipment interface is provided in the private branch exchange. The terminal equipment provides a communication channel between the additional equipment and the additional equipment driver in the private branch exchange via which the additional equipment and the additional equipment driver communicate according to a protocol specific to the additional equipment.
Claims12
An arrangement for coupling optional additional equipment to terminal equipment of private branch exchanges via an additional equipment interface, comprising:
- terminal equipment of the private branch exchange having an option bus that physically realizes an additional equipment interface and via which arbitrary additional equipment is connectable thereto;
- an additional equipment driver in the private branch exchange, the additional equipment driver realizing an additional equipment protocol and the additional equipment driver being specific to the additional equipment;
- the terminal equipment and the private branch exchange having communication devices, said communication devices realizing a communication channel between the additional equipment and the additional equipment driver in the private branch exchange, the additional equipment and the additional equipment driver communicating over the communication channel according to the protocol that is specific to the additional equipment.
