Data Sheet USE2.OB Interface Attachment for Local Battery Telephony The USE2.OB interface attachment converts the digit codes used in the system into allocated LB call signals and vice versa. Voice monitoring can be set in this model. When the option for voice monitoring is set, after a pause in conversation of 60 seconds, the conversation connection is terminated. The area of use for the USE2.

Data Sheet USE2.OB Interface Attachment for Local Battery Telephony Function Description: One LB line in 2-wire technology can be connected per USE2.OB interface (4wire technology only with double the number of interfaces). The following functions are active for LB operation: - Call recognition Call generation Voice recognition Codec + filter The interaction of the individual functions is illustrated in the following block diagram. USE2.

Data Sheet USE2.OB Interface Attachment for Local Battery Telephony Call Recognition The attachment, call recognition, receives the incoming dialling information. The dialling information is galvanically separated and adapted through an optocoupler, passed to the microcontroller (control unit) and there processed. Call Generation The attachment, call generation, is switched through relay contacts over the LB line and generates the dialling pulses controlled by the processor.
