The KE901 enables mode selectabel switching, insertion of bridges, turn on a measurement device on the far end of line, connect through another exchange, switching on a second acccess line. Developped for the current communication services as ISDN, ADSL2+ and VDSL2 the device has small impact on measurements through 30 MHz on the far end. Remote-Controlled switching functions up to 20 km distance are possible without influence on other services on the line.

After connecting the Remote Unit KE905 at the multiplier or intermediate distribution frame a tone can be send either to one or two access lines. For acces line 1 there are two different tones selectable. If no tone is necessary because the end of line is known, the service can be switched through to the customer. This enables him to use his service as long as possible.

After connecting the controllers on the customer's pair the control key switches the tone tracing off. The remote-commands are send with 8 keys from the Control Unit KE910. The signals are modified DTMF-Signals to avoid static. Succeded the switching function the KE910 sends a tone and shows a short light up from the Info-LED. If the remote-command wasn't executed there will be a pulsed tone.

For active tests like crosstalk, balance, spectrum-analysise etc. the line can be cleared or switched to another measurement device on the far end. In spite of the measurement device there can also b aenother Telephony / xDSL Port attached. This second local line can be switched to one or another acces line so it is possible to measure the interference (NEXT).
