The following messages are normal outputs of the diagnostic process and do not
affect the operation of the card.
■ Diag TR number , Not attempting dial tone training
(/vs/switch/analog/noDTtrain exists)
For some switches, dial tone training is turned off because if the Lucent
I
NTUITY system tries to get dial tone from many switch ports at one time,
failures can occur on the switch side.
■ Found Loop current on channel number
This message indicates that there is a working telephone line attached to
the voice port.
■ Request to diagnose Tip/Ring number completed
This message indicates that all requested tests have been completed.
The following list shows messages printed in the Diagnose Equipment Results
screen that could signal problems.
■ No loop current on channel number
OR
Channel number changed to state FOOS
The Lucent I
NTUITY system does not detect a working telephone line
connected to the voice port. If this occurs, do the following:
1. Verify that the telephone line is securely connected to the voice
card and the switch.
2. Verify that the analog line is set up properly on the switch. See the
switch integration document included with your Lucent I
NTUITY
system documentation set for more information.
3. Verify that the switch port has a dial tone, by removing the analog
line, plugging in an analog telephone, and listening with the
handset for dial tone. If there is dial tone, the voice card is likely the
problem. If there is no dial tone, the problem is on the switch side.
Verify switch wiring and administration.
■ Diag TR number : No dial tone frequencies set
The Lucent I
NTUITY system did not detect dial tone, but it did detect loop
current (phone line is attached). This could be a result of excessive load
on the switch circuit pack. If this occurs, do the following:
1. Verify that Lucent I
NTUITY system analog lines are distributed over
several switch circuit packs.
2. Verify that the switch administration for the ports is valid.
