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.OB attachment is train stations, stops or routes
which are not occupied by a traffic superintendent anymore and at which a signalling system is not required. The digital exchange system DVS-21 with
USE2.OB interface transfers connections to occupied electronic control signal
boxes or to control centres.
