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.

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.
