No Active Data Services on the Line
No POTS service on the line
No active data services on the line which can be detected by
the ARGUS 42 (0KHz) empty pair?
ISDN BRI U layer 1 not present, might be down due to
inactivity of the P-MP line, or NT1 is disconnected
ADSL might be inactive (0KHz) or signal is below the input
sensitivity
What can be tested?
Performing an R/C measurement to check the line
1. Result is a capacitance: line is open or terminated with capacitance (e.g. splitters
with a 50nF or 100nF capacitance)
2. Result is a resistance: line might have a resistive fault, remote loop to measure
the length, or has a resistive termination
The ADSL connection can be tested by pressing ADSL
Profile
(can be Annex A or Annex B in this case), or the
ISDN BRI U interface can be tested by pressing LINE U interface TE automatic
Tester connected to the wire pair:
