■ 40975 indicates that the terminal equipment was on-hook when
ring-tip was detected during ringing. This usually indicates a failure
in the terminal equipment or the type of terminal has a low ringer
impedance. Call the terminal equipment and verify that the terminal
rings. If the terminal does not ring, then replace it. Otherwise, use
test port PCSSpp and follow the procedure for Test #48.
■ 40977 indicates that no terminal equipment was connected when
ringing was attempted. Run the short test via the test port PCSSpp
command, and follow the procedure for the results of Test #48.
b. This is a software audit error that does not indicate any hardware
malfunction. Run Short Test Sequence and investigate associated errors.
c. This error type indicates that the circuit pack has been removed or has
been insane for more than 11-minutes. To clear the error, reseat or replace
the circuit pack.
d. This is an in-line error and can only be resolved over time. This error
indicates that ringing voltage is absent. If only 1 analog circuit pack in the
system has this problem, then replace the circuit pack. If only analog circuit
packs on a particular carrier have this error, then the ringing generator may
not be connected to this carrier. If analog circuit packs on many carriers
have this error, then it is probably a problem with the ringing generator.
e. Test #48 may cause some terminal equipment to ring briefly during daily
maintenance. If this disturbs the customer or the terminal equipment,
disable it by setting the Tests field on the change station extension form
to n. On some software releases, this will also disable Tests #6, 7, 161, and
35.
