35 Understanding common error types 
Error type 18 — busied out
Error type 18 is a reminder from the switch that a component has 
been busied out. The busyout command is used to temporarily 
disable a component and is usually used before you test or replace 
a component.
Use the 
release command (permissions enabled) to restore a 
component to its normal operating mode.
For example, you receive a complaint that a phone does not work. 
As part of your diagnosis, you:
nuse status station 
OR
nview the hardware error report for error 18
To view a hardware error report for error 18:
1. Type 
display errors and press RETU RN.
The Hardware Error Report screen appears. 
2. Fill in the Error Type field and press 
RETU RN.
In our example, type 18.
The Hardware Error Report for error 18 appears.

The log entry indicates that extension 1234, a digital line, is 
busied out (Err Type 18).
Use the 
release command (permissions enabled) to remove the 
busyout status from the station. In our example:
1. Type 
release port 01A0901 (permissions enabled) and 
press 
RETU RN.
The station is no longer busied-out. 
Error type 513 — equipment “missing”
Error type 513 notifies you that equipment such as phones, data 
modules, or circuit packs, are administered but not physically 
connected to the switch.
For example, view a hardware error report for error 513:
1. Type 
display errors and press RETU RN.
The Hardware Error Report screen appears. 
2. Fill in the Error Type field and press 
RETU RN.
In our example, type 513.
The Hardware Error Report for error 513 appears.

Alarms and errors 
37 Understanding common error types 
In this example, a digital phone is missing. A port on the digital 
line circuit pack (DIG-LINE) at cabinet 1, carrier C, slot 05, 
port 07 does not have its administered equipment physically 
present (Error Type 513).
To fix error 513 in our example:
1. Plug the phone into the jack assigned to port 01C0507.
2. Type 
test station 7157 (permissions enabled) and press 
RETURN to test the phone.
The system will clear the error only after the system runs 
its administered checks and diagnostics.
Error type 1 — circuit pack removed
Error Type 1 often indicates that an administered circuit pack has 
been removed.
To correct the problem and clear Error type 1:
1. Replace and latch the circuit pack in its administered slot.
The next time the system runs its routine maintenance 
program, it should be able to “see” the circuit pack and the 
error will not appear.

Preventing alarms and errors
This section lists a few common causes of unnecessary alarms.
Turn off maintenance
The Remote Loop-Around Test sends a burst of current to 
activate a phone’s ringer. If the ringer responds, the test detects 
the return. Data modules, fax machines and modems do not have 
ringers and do not respond to this test. This generates an error on 
that port.
You should turn off this test for data modules, fax machines and 
modems. Turning off the test does not affect the performance of 
any of these devices.
To turn off the maintenance test:
1. Type 
change data-module extension and press RETU RN.
The following screen appears:
Data module screen
2. Change the Remote Loop-Around Test field to n.
3. Press 
EN TER to save your changes.

39 Preventing alarms and errors 
Remove unused circuit packs
Occasionally, a company upgrades phones from the 7000-series 
analog model to the 8400-series digital phones. The upgrade 
process is to:
1. Remove the analog line and trunk administration
2. Remove the old analog equipment
3. Rewire the workplace for the new digital phones and jacks
4. Administer the new digital phones and circuit packs
If the analog circuit packs remain physically plugged into the 
system and are still administered as circuit packs (even though 
the administration is removed in Step 1 above), the system 
generates errors. This stops when you remove the administration 
(
change circuit-pack UUCSS) for this unused circuit pack.
DS1 administration
Depending on whether a DS1 circuit pack is present and whether 
its ports are assigned or not, the system reports faults according to 
the following table:

Using features to troubleshoot
You can use some DEFINITY features to help you identify if 
your system is having problems or to help you diagnose problems 
you know are occurring. The table below shows you which 
features to use for various kinds of system problems.
Automatic Circuit Assurance
You can use Automatic Circuit Assurance (ACA) to help identify 
faulty trunks. If activated (
change system-parameters 
features
), your system notifies you with a referral call when it 
detects unusual trunk usage like very short or very long calls. It 
needs to be turned on for each individual trunk group.

The referral call arrives on an idle call appearance. If you answer 
the call, your display shows:
nthat the call is an ACA call
nthe trunk-group access code
nthe trunk-group member number
nthe reason for the call (short or long holding time)
To use ACA on a G3V2 or older switch
1. Assign an ACA button to your phone.
2. Press the ACA button to activate your phone for referrals.
3. When you receive an ACA referral call, answer the call.
4. Record the information listed on your display to use for 
further troubleshooting.
To use ACA on a G3V3 or newer switch
1. Assign an ACA-Halt button to your phone.
2. Leave the ACA-Halt button OFF to keep your phone 
active for referrals.
3. When you receive an ACA referral call, answer the call.
4. Record the information listed on your display to use for 
further troubleshooting.

Busy Verify
You can use Busy Verify to place test calls to check the busy 
condition of trunks, phones, or hunt groups. This test helps you 
determine if the trunk, phone, or hunt group is busy because of 
heavy use or appears busy because of a problem.
To use Busy Verify, you should administer a Busy Verify button 
on your phone.
To busy-verify a phone
1. Press the Busy Verify button on your phone. 
The busy verify light turns green.
2. Dial the extension of the phone you want to test.
