- Telephone function and BERT, selectable B-channels, loopbox 

function for B-channels 

- BERT in D-channel

• Time measuremnet: time for connecting, time offset of 



B-channels

• Layer 1 tests and bus supply: Measurement and evaluation of the 

phantom feed (OK, NORMAL or Restricted Power) and the L1 
recieve- and send-signal level of NTBA or PBX  

• Cable testing*: Check-up of the terminating impedance in detail. 

If there are crossed wires or short circuits, the tester displays the 
right wire.
