DCC Port
Connector
9-pin miniature D-type.
Use this port to insert and drop either the D1-D3 DCC channel
or the D4-D12 DCC channel. The first bit of data inserted will be
put into the MSB of the DCC channel. The MSB of the dropped
data bytes will be output first. The transmit (drop) and receive
(insert) capabilities are independent, that is the transmit and
receive clock rates can be set to different rates. The instrument acts as a DCE (Data Communications Equipment), supplying the clock signal for both drop and insert operation.
Rates
D1-D3 DCC: 192 kb/s, D4-D12 DCC: 576 kb/s
Signal Type Unipolar differential signal as defined in ANSI
EIA-422-B and EIA-423-B.

Using Online Help
Create Your Own Help Files
The help files you create to install on the instrument must be in
HTML format. You can create them using an HTML editor tool,
or with a word processor that will save them as HTML files.
When creating your files for online use follow these simple
guidelines:
• Use only a sans serif type font (such as Arial) of size 12, 14
or 16 point, Normal or Bold - DO NOT use italic as this font
is not supported on the instrument and can cause problems
with the presentation of your document.
• Any images you include should be either GIF or JPEG.
• Write several short documents rather than one long one. A
long document takes longer to open.
• Design a page size and layout that’s appropriate for the size
of the instrument display.
• Have all the documents and images in one folder/directory.
The instrument does not currently support file tree structures.
• Total size of the files should not be more than 1.44Mb.
CAU T ION
The instrument supports HTML Standard 3.2 - presentation
or operation of elements using later HTML standards are
not guaranteed to operate or display on the instrument.
The following procedure was used to create the example help
files that are installed in the instrument - you can view the
results on the online help in the ‘Users Own Help Files’ section.
N O TE
The example help files can be copied from the instrument and
amended for your own use. See “Copy Your Own Help Files to
Disk” on page 53.
1 A standard word processor was used to create the content.
Keeping your document short, two pages or so, will make it
quicker to load and navigate when on the instrument.
2 Save the document as HTML with the file extension html
NOT htm.

5 To do this, open a new file and create a hypertext link from
this file to each of your help files.
6 Save the document as HTML. You must name this index file
ownhelp.html. It is important that you use this name as it is
used to access your files within the instrument.

Using the SignalWizard Test Feature
SignalWizard checks the test ports for valid signals. A signal is
valid if its power level and frequency are with in the specified
limits of the port it is connected to. The line rate and interface
level for optical signals is determined along with the termination, signal level and line coding for electrical signals.
SignalWizard then scans all STS/AU channels (up to 192) and
selected 'expanded' VT/TU channels simultaneously for error
and alarm information. For VT/TU channels that are not
'expanded' in the display, error and alarm information is
obtained sequentially (within milliseconds).
SignalWizard can also scan PDH/DSn sub-channels, and
shows which channels are unequipped and the type of service
being carried by equipped channels.
For information on connecting to a network when testing with
SignalWizard, see:
• “In-Service Testing” on page 68
• “Out-of-Service Testing” on page 69
To monitor a signal with SignalWizard:
1 Press <Smart Test>, choose SignalWizard then press
<Select>.. A progress indicator is displayed. If more than
one valid signal is detected, the port selection window is
displayed. Select the port you want to examine, then select
Continue. If only one valid signal is detected or if the instrument is in Thru-Mode, the Channel Overview window will
automatically appear on the display. For information, see
“Understanding SignalWizard Overview Window” on
page 63.
If SignalWizard detects a DSn/PDH signal, then PDH/DSn
Channel Scan will automatically be launched. A window
will appear showing the status and structure of all channels.
If no valid signal is detected, you can re-scan the ports or
return to the main instrument.

Monitoring Path Trace Messages
When running SignalWizard any routing errors in the network
will be shown in the Overview window.
During the installation and commissioning of new services, or
troubleshooting, the ability to generate and monitor path trace
messages is essential. This allows you to confirm correct routing paths through network equipment with software controlled
routing capability. You can also use path trace messages for
checking routing performance of network elements during protection switching to confirm the correct signals have been protected in fault conditions.
You can view all the J1 path trace messages for the received
signal at the same time. Alternatively, you can view all the J2
path trace messages associated with VT/TU channels in a
selected STS/AU.
To view path trace messages:
• Use the arrow keys to select the STS/AU channel of interest. View the J1 path trace message at the bottom of the
display.
To list/search all J1 Path trace messages in the receive signal:
• Press <Menu>, choose Trace Messages then press
<Select>. Select List Current Levels, a trace message window will be displayed.
• Press <Menu>, choose Trace Messages then press
<Select>. Select Search Current Level. Enter the trace
message you are searching for in the dialog box, then select
OK.

Out-of-Service Testing
You can use the instrument transmitter in conjunction with
SignalWizard all channel test feature to test each path carried
within a tributary or line signal. You can apply the test signal to
the tributary or line side of the network element.
Applying a test signal to the line side of the network element
may reduce the number of ports that need to be checked. SignalWizard will identify the type of network paths present in the
received signal (including the mix of channel types), and the
traffic carrying status of each channel (showing which are
equipped).
Typical tributary and line network test connections are shown
below.

Hints and Tips
Avoiding Problems When Making
Measurements
Bit errors can occur due to network defects (such as faulty network elements, damaged optical fiber or dust/dirt particles in
the fiber connections) or problems with the test environment/setup. Follow the steps below to avoid problems when
making measurements.
To avoid introducing errors when performing tests:
• Ensure that optical fibres connecting the instrument to the
network are not damaged - check that fibres have not been
crimped.
• Avoid acute bends in the fibre. Ensure that fibres only have
gentle arcs.
• If the instrument is left unattended for a long term test,
ensure that the equipment is not in a position where people
will disturb the connecting fibers.
• Ensure that all fiber connections are clean and dirt-free. Use
a fiberscope to measure the cleanliness of a (unpowered)
fiber. A poorly cleaned fiber results in a drop in power. Alternatively, use a power meter (e.g. the instrument’s internal
power meter) to measure the power at the end of a fiber, the
other end of which is connected to the network.
• Before connection is made, always clean the connector ferrule tip with acetone or alcohol using a cotton swab. Dry the
connector with compressed air. Failure to maintain cleanliness of connectors is liable to cause excessive insertion
loss.
• Ensure that the correct time and date is set on the instrument.

Hints and Tips
Avoiding Optical Receiver Overload
Check when connecting an optical transmitter to an optical
receiver that you do not overload the receiver. This applies to
elements under test and also the instrument receiver input
ports.
On the instrument connector panel the following output/input
power level information is printed:
Tx Optical Out
ports:
Maximum available output power
(color - black).
Rx Optical In ports:
Maximum input power (damage
level) the receiver input can accept
before damage occurs
(color - yellow).
Recommended input power operating range for signals applied to the
receiver (color - green).
When performing tests, it is recommended that you drive the
optical receiver with a signal that has an average power in the
middle of the receiver’s operating range (mid-way between the
upper and lower levels printed next to the Optical In port).

Hints and Tips
Cleaning Optical Connectors
You should clean the optical connectors at regular intervals
using the following materials:
Description
Agilent Part Number
Compressed Air Can or
Blow Brush
CAU T ION
Isopropyl Alcohol
8500-5344
Lens Cleaning Paper
9300-0761
Swabs
5080-5400
Do not insert any tool or object into the optical IN or OUT
ports of the instrument as damage to or contamination of
the optical fiber may result.
1 Disconnect the instrument from the Power Line or switch
off the laser transmitter before commencing this cleaning
procedure.
2 Remove the adapters from the optical IN and OUT ports by
flipping back the lever on the optical adapter.
3 Using the blow brush with the brush removed blow through
the ferrule of the standard flexible connector and the
adapter.
4 If the optical fibre of the fixed connector requires further
cleaning this entails disassembly of the module. This should
be carried out only by suitably trained service personnel.
5 Apply some isopropyl alcohol to a piece of the cleaning
paper and clean the barrel of the adapter. Using a new piece
of cleaning paper, clean the face of the adapter. Repeat this
operation, using a new piece of cleaning paper each time.
6 Use a blow brush or compressed air to remove any particles
of cleaning paper which may be present.
7 Replace the adapters in the optical connector. Secure in
place by clicking the retaining lever back into position.
