The Signaling Advisor makes it easy for you to start monitoring, even if you  
don’t know what timeslots or protocols are being used for signaling. The auto  
configure tool configures the instrument’s receiver to match the bearer and  
then searches the bearer for signaling links (timeslots that are carrying  
signaling information). The correct protocol stack will be built based on  
signaling messages.  
SS7 Monitoring  
If the default protocol stacks do not match the signaling being tested, or a  
special variant is required, you can quickly change the assigned protocol  
stack graphically. Figure 1 shows a typical protocol stack.  
Figure 1: Protocol Stack configuration  
Real-time Analysis  
The SS7 Signaling Advisor monitors up to 16 bidirectional bearers and up to  
32 duplex signaling links simultaneously (spread across one or more bearers).  
Each signaling link can carry a different protocol. Monitored data is  
processed then automatically stored to hard disk.  
Post-capture Analysis  
All of the capabilities available for real-time analysis are also available for  
use on previously logged data. The user may perform the same operations as  
in real time.  
Applications  
In addition to the default protocol analysis application, it is possible to setup  
multiple applications for statistical analysis or call traces.  
Figure 2 shows a typical real-time measurement setup.  
A wide variety of measurement triggers and filters can be set based on  
almost any interesting variable or event.

Viewing Messages  
Monitor Tool  
The main traffic overview display shows (chronologically) every message  
captured for each signaling link. This overview display shows one line of  
essential information for each message. The type and format of information is  
displayed in columns and is controlled by the user. Each message can be  
decoded further to show a one line description per octet/field. Figure 4  
shows a typical traffic overview.  
Time Stamping  
Each captured message is given a timestamp. The timestamp reference is the  
instrument’s internal clock.  
Alarm View  
If a physical layer alarm occurs (e.g., AIS), a pop-up alarm view window  
appears showing software LEDs for all bearers. This view can be expanded to  
show individual alarm conditions.  
Link Status and Message Validation  
Link status view and link loading information is available for each link under  
test. The software can highlight message-encoding errors found in received  
messages. In the traffic overview display, a message with an error is  
highlighted in red. The ‘‘message sequence validation’’ function advises the  
user of errors in message sequences (e.g., messages which do not fit into a  
normal call pattern). The erroneous messages are highlighted in red.  
Data Import  
It is possible to import data from the Agilent acceSS7 monitoring system or  
from the Agilent 37900D signaling test set or from a text file into the  
Signaling Advisor.

Call Trace Overview  
Call Trace Tool  
The graphical call trace application traces calls (or message sequences) across  
all links and groups the messages together. It is  
therefore a very powerful facility for troubleshooting, particularly since it  
operates in both real-time and post-capture modes.  
The application produces a user-configurable window which contains one line  
for each call. For example in the case of ISUP, this window would typically  
show:  
Call identifier  
Call status  
Call duration  
Call setup time  
Call cleardown time  
Called party number  
Calling party number  
OPC/DPC/CIC  
Release cause  
Graphical representation of call phases  
Call Trace Tool

Graphical Statistics  
Statistics Tool  
User-definable graphical statistics are available in real-time or postcapture modes. There are  
several SS7 message transfer part (MTP) statistics, as well as user part specific statistics (e.g.,  
message types or release causes). Statistics are typically counts or ratios. The statistics may be  
displayed graphically as:  
2D Bar charts  
Radar diagram  
Figure 7: Shows a typical statistics graph.  
Tabular Statistics  
Tabular statistics are drawn by call traces. This provides a more detailed and  
dynamic view of network performance, incorporating several programmed  
measures (handovers, errors, call success rates etc).  
Time-based Statistics  
It is possible to produce the graphical statistics as a tabular time series,  
where the intervals can be set from one minute to 24 hours.  
Statistics Thresholds  
The user can set lower and upper thresholds which, when exceeded, will  
result in color changes to the statistical graphs to highlight ‘‘alarm’’  
conditions.  
Page 9 of 16  
Call-based Statistics  
The most advanced statistics features involve using the call trace application  
to evaluate call based statistics such as call completion ratio, min/mean/max  
call setup times, and min/mean/max call durations.  
Data Export  
Statistics can be exported to a CSV (Comma Separated Value) file for further  
analysis in another application (e.g., spreadsheet or database).

Emulation is the ability to define and send signaling messages in a predefined  
sequence to a unit under test and respond to received messages.  
EmuLite  
Traditional emulation tools require complex programs to be written to perform  
even the simplest of tasks. Writing programs using a programing language is  
time consuming, error prone and distracts engineers from solving signaling  
problems rather then solving programming problems.  
EmuLite revolutionizes the way in which emulation is performed through use of  
its key capabilities which are summarized in this section.  
Graphical Message Editor  
The EmuLite intelligent field based message editor allows message creation and  
modification using familiar protocol field names. When creating a message, users  
are shown the valid selections from which they can choose, significantly  
reducing the possibility of error. Message fields can be saved into variables.  
EmuLite automatically updates all lengths, pointers and odd or even indicators.  
Figure 9: Message editor.  
Page 11 of 16  
Graphical Sequence Editor  
Tests are configured using ‘drag and drop’ icons such as arrows, branches and  
timers. These automatically generate test scripts -- a time-consuming and  
complicated task if programmed manually. More time can therefore be spent  
diagnosing signaling problems without the need for programming.  
Call Simulation  
Users can generate test sequences automatically from previously captured data  
as opposed to entering all the data manually. A sequence of related messages  
captured using the call trace function can be copied directly to the EmuLite  
sequence editor. This sequence and the messages within it can then be modified,  
if required, to create a test ready for execution.  
Conformance and Compatibility Tests  
NIIF (formerly NOF) tests and high-speed SS7 sequences are included -- ready  
to run.  
Test Manager  
The test manager allows single or multiple tests to be selected and run  
sequentially. Results are stored in the test log and can be optionally logged to a  
.CSV file during execution. The EmuLite status view shows the progress of each  
test by displaying the messages and a PASS or FAIL indicator.  
Graphical Test Analysis  
EmuLite’s status view identifies all tests which have failed. Advanced decode  
analysis tools allow messages to be examined in detail providing quick fault  
identification.  
Fully Integrated with Monitor  
EmuLite is fully integrated with the Signaling Advisor’s monitor software. All  
analysis tools such as call trace, statistics and decodes are available for use. The  
flexibility of this software also allows existing monitor-only customers to  
upgrade easily to EmuLite.  
Figure 10: Test analysis display.

Today, more developers and field engineers than ever are faced with the  
challenge of effectively analyze signaling networks. For Signaling Advisor, ease of  
use was one of the primary design goals. A graphical and self-explanatory user  
interface allows the user to easily execute tests and identify problems quickly.  
You Don't Need To Be A  
Signaling Expert to Operate  
the Signaling Advisor  
Find Problem Calls Faster  
Signaling Advisor has graphical call trace, statistics and comprehensive filters to  
allow rapid message isolation and decoding.  
So, when you need to find one specific problem call amongst thousands you can  
do it in only four mouse clicks. This means that you can resolve your customers’  
problems fast.  
Roll Out New Services Faster and Increase Revenue  
Signaling Advisor has a unique ‘‘no-programming-needed’’ graphical emulation  
environment -- EmuLite. You can even copy messages and calls from monitoring  
sessions directly into EmuLite with just three mouse clicks.  
When evaluating the operation of new network elements and services, you need  
to develop test sequences very easily and quickly.  
With EmuLite you can do just that -- no programming required. You can  
complete more tests in less time.  
Improve Productivity as Networks Become More Complex  
Signaling Advisor features extreme ease-of-use. Automatic configuration, unique  
Graphical Call Trace, GPRS session trace and intuitive statistics functions mean  
that you don’t need to spend time reading the instruction book.  
Even a nonexpert in signaling can easily interpret network behavior using  
graphical cues. And experts can achieve even more every time they start testing.
