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 sig-

nalling 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.

Function Description:

Application example LB line forwarding

Using the USE2.OB interface the DVS-21 can forward calls originating from a local
battery telephone (LB telephone).
One USE2.OB attachment is required per LB device (LB line in 2-wire technology).
Incoming and outgoing calls can be transferred over multiple DVS-21 systems using
E1 connections (4FTR carrier card with E1 attachment).
