Signaling Advisor -- - 37907A

Technical Overview

The Agilent Technologies Signaling Advisor is a comprehensive and powerful
test and troubleshooting instrument. It enables the user to find problems in
today's complex wireless and wire- line telephone networks faster. Businesses
and consumers are increasingly sensitive to even a minor deterioration in
service quality. To maintain customer satisfaction and loyalty, your
technology teams need tools that help identify potential problems and resolve
faults quickly and effectively... They need an Agilent Technologies Signaling
Advisor
The Signaling Advisor provides detailed test and analysis capabilities for
signaling on modern wireless and wire- line telephone networks such as SS7,
Cellular, PCS, GSM and GPRS networks. It provides robust and reliable
measurements and analysis that go beyond decoding and filtering data.
The Signaling Advisor mainframe is a robust dispatched trouble- shooting tool.
Add any appropriate optional decodes and link interface modules, and you
are ready to test across multiple links involving different protocol standards
for example, at access network interfaces. At the core of each Signaling
Advisor, the intuitive graphical user interface makes measuring and
understanding results easier for signaling engineers, enabling them to check
performance and troubleshoot problems in signaling systems quickly and
accurately.

Summary of Contents for Agilent Technologies 37907A

  • Page 1 Agilent Technologies Signaling Advisor -- - 37907A Technical Overview The Agilent Technologies Signaling Advisor is a comprehensive and powerful test and troubleshooting instrument. It enables the user to find problems in today’s complex wireless and wire- line telephone networks faster. Businesses and consumers are increasingly sensitive to even a minor deterioration in service quality.
  • Page 2 Signaling Advisor Key Benefits A range of link interface modules (LIMs) provide the physical interface to network equipment. Each LIM connects to one type of physical interface (e.g., E1 or T1), providing access to all signaling links on up to four bidirectional bearers.
  • Page 3 Signaling Advisor Features and Functionality General Feature summary Dedicated software for Cellular, PCS/GSM, GPRS, UMTS, cdma2000 and SS7 signaling networks Windows 98® based operation Multitasking applications (protocol analysis, statistics, call trace) Real- time or post- capture analysis Connect to up to 16 duplex physical bearers (E1 or T1, DS0, V.35, RS- 232, RS- 449) Analyze up to 32 duplex signaling links (8, 16, 32, 48, 56, and 64 kb/s) Analyze full duplex Ethernet/Fast Ethernet GSM sub- rate signaling...
  • Page 4 SS7 Monitoring 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).
  • Page 5 Ethernet Monitoring GPRS and cdma2000 Figure 2: Measurement setup display. The Fast Ethernet interface and software provides real- time and post capture analysis of Ethernet protocols. Use the powerful Agilent Advisor 10/100 LAN software to analyze your IP links with the Signaling Advisor.
  • Page 6 ATM Monitoring The ATM interfaces and software provides real time and post capture analysis ATM and encapsulated LAN protocols, including high speed SS7 and W- CDMA UMTS as well as cdma2000. Monitor and troubleshoot all aspects of the UMTS Radio Access Network (Iu, Iub and Iur interfaces). Use the powerful Agilent Advisor ATM software with the Signaling Advisor to analyze your ATM links.
  • Page 7 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.
  • Page 8 Call Trace Tool Call Trace Overview 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.
  • Page 9 Statistics Tool Graphical Statistics 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...
  • Page 10 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).
  • Page 11 EmuLite Emulation is the ability to define and send signaling messages in a predefined sequence to a unit under test and respond to received messages. 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.
  • Page 12 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.
  • Page 13 You Don't Need To Be A Today, more developers and field engineers than ever are faced with the challenge of effectively analyze signaling networks. For Signaling Advisor, ease of Signaling Expert to Operate use was one of the primary design goals. A graphical and self- explanatory user the Signaling Advisor interface allows the user to easily execute tests and identify problems quickly.
