ANL-24-L (24-Port Analog Line)
Issue 5 October 2002

Notes:
a. Run the Short Test Sequence first. If all tests pass, run the Long Test
Sequence. Refer to the appropriate test description and follow the
recommended procedures.
b. Minor alarms on this MO may be downgraded to Warnings based on the
values in set options.
c. Error type 1: in-line errors, can only be resolved over time.
■
40960 indicates that too many simultaneous incoming ringing
attempts were made on this board. Only 4 ports on a board may ring
simultaneously. A 5th incoming call will cause an inline error from
the board.
■
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, 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. Use test port PCSSpp to run the short test
and follow the procedure for the results of Test #48.
d. Error type 15 is a software audit error that does not indicate any hardware
malfunction. Run Short Test Sequence and investigate associated errors.
e. Error type 130 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.
f. Error type 257 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, replace the circuit pack. If only analog circuit
packs on a particular carrier have this error, the ringing generator may not
be connected to this carrier. If analog circuit packs on many carriers have
this error, it is probably a problem with the ringing generator.
g. Error type 513: Test #48 applies momentary ringing voltage to phone
equipment and monitors resulting current flow to determine whether the
equipment is connected to the port. Test #48 may cause some phone
equipment to ring briefly during daily maintenance. If this disturbs the user
or the phone equipment, to disable Test #48 use change station
extension
and set the
Tests
field to n. On some software releases, this will also
disable Tests #6, 7, 161, and 35.
