VER 0: TEST OK

Overview
No obvious trouble was detected on the line. However, there may still be a problem with parts of
the loop that were not tested. In general, when the system tests OK, there is no problem indicated
by any of the detailed results. For metallic testing, the DC resistances and voltage are within the
acceptable range, the AC signature is valid, and a loop length is reported. For higher-layer
testing, such as Broadband and VoIP, the reported statistics and/or graphics indicate that each of
the tested layers and network elements is functioning normally. For more information, see the
section of the Test Request Guide that corresponds to the particular test that was run,

Additional Information
This example is a TEST OK for a single party line. Note the CRAFT and LoopCare DC signatures
show high resistances (3500 K ohms) and low voltage (0 Volts). The AC signature indicates the
presence of a ringer tip to ring. The central office check indicates that the line circuit arrangement
of battery and ground was valid and LoopCare was able to draw and break dial tone properly. In
addition, the capacitive balance (100%) and the longitudinal balance (65 DB) were both good.
Finally, the length of the loop is given as the last piece of information about the line.
Also take note that you may occasionally get a TEST OK message if there is a keyset on the
customer's line.
bPON Feature
VER 0: DROP TEST OK

A bPON test on a customer drop detected no obvious problems.
VER 0A: TEST OK
Overview
VER 0A indicates that either a FULL(X) or LOOP(X) test request was run and the signatures
returned show an ADSL served line.Testing indicates that the line is OK. One of the following
summary messages appears.

VER 0B: CPE or HIGH
RESISTANCE OPEN

Overview
LoopCare did not detect any obvious trouble on the line, however, it did find either a CPE
termination or a high resistance open on the line. In most cases this will indicate that it is a CPE
termination. The remote possibility exists however, that it could be a high resistance open
problem.
LoopCare sets VER 0B when it finds the termination through the Breakthrough CPE Detection
tests. See the System Description for more information on this feature. VER 0C: CPE or HIGH
RESISTANCE OPEN

Overview
LoopCare did not detect any obvious trouble on the line, however, it did find either a CPE
termination or a high resistance open on the line. In most cases this will indicate that it is a CPE
termination. The remote possibility exists however, that it could be a high resistance open
problem.
Additional Information
This example is a TEST OK for a single party line, Centrex lines, Key Systems, and loop-start
PBX lines with CPE termination. These lines may or may not have line records. Note the CRAFT
and LoopCare DC signatures show high resistances (3500 Kohms) and low voltage (0 Volts). The
message "CPE or HIGH RESISTANCE OPEN" is shown because of the remote possibility that
there is a high resistance open condition on the line. It should be noted that a ringer configuration
test is not performed here.
The central office check indicates that the line circuit arrangement of battery and ground was
valid and LoopCare was able to draw and break dial tone properly. In addition, the capacitive
balance (100%) and the longitudinal balance (65 DB) were both good. Finally, the length of the
loop is given as the last piece of information about the line.
VER 0D: OPEN IN OR DSL
TERM

Overview
LoopCare has detected either an open condition or an xDSL termination with an AC signature
similar to that of an open condition on the loop. It has been determined that the open is in or very
close to the Central Office. There is an offset value (in feet) stored in the computer for each test
unit. If the open is detected within this offset limit, it is considered an open in. An open is a
physical break in the line.

VER 0D: OPEN IN OR DSL TERM

3500 0 R-G 3500 0 R-G 1038 R-G
VER 0E: OPEN OUT BALANCED
OR DSL TERM

Overview
LoopCare has detected either an open condition or an xDSL termination with an AC signature
similar to that of an open condition on the loop. It has been determined that the open is out of the
Central Office. The capacitive balance, which indicates the difference between the capacitance in
each side of the line, is 99% or better.

VER 0H: ROH DETECTED
DURING TEST

Overview
VER 0H denotes that an open loop condition was found during testing and that an ROH condition
occurred during the test. This is an indication that there is a undetectable CPE on the loop and
that it went off-hook during testing. This condition could be caused by a FAX or Answering
machine or a human.
When this condition occurs, the data from the Central Office portion of the test is discarded
because of the unexpected short on the loop. Run a CO test to determine the validity of the line
circuit and dial tone. If the CO test passes, treat the VER 0H same as a VER 0. Running a LOOP
test by itself results in a VER 41 or other open VER code. This is normal. The loop should be
considered terminated with an undetecta
