Catapult IMS Testing Covers Four Primary Functions
Catapult offers the most comprehensive IMS test systems in the industry by providing the protocol breadth, stack depth, and traffic/signaling capacity required to stress and verify new IMS network elements. Catapult IMS test systems allow users to create test cases and tailor test configurations for any of the four primary IMS functional areas: Access Network, Core Network, Interworking Elements, and Application Server. Additionally, Catapult test systems support the complex lower layer protocol analysis essential for IMS testing.
Catapult has made ordering easy by introducing four IMS protocol bundles. Each bundle includes all of the protocols necessary to verify one of the four primary IMS functional areas:
- Access Network. Protocols for PDF, P-CSCF and Application Server network elements testing
- Core Network. Protocols for call session control function (P-CSCF, I-CSCF, S-CSCF) network elements testing
- Interworking Elements. Protocols for media and signaling gateways (IM-MGW, SGW), MGCF and BGCF network elements testing
- Application Server. Protocols for Application Server, HSS and SLF network elements testing
For specific information on IMS protocol bundles, functionality, performance levels, supported specifications, and protocol variants, please contact your Catapult representative.
DCT2000® Increases Data Capacity on IuPS and Gi Interfaces
Catapult now offers downloadable scripts for testing very high packet data rates across the IuPS and Gi interfaces. The new XStream packet generator utility available on DCT2000 m500 test systems provides:
- Persistent connections to generate maximum packet data load rates filling the test channel
- High-level transmit and receive statistics
- Integrity verification of high load capacity for the device under test throughout the development and test stages
TTCN-3 Adapter Available on DCT2000
Testing and Test Control Notation Version 3 (TTCN-3) is an ETSI and ITU-T standardized language intended for writing detailed test specifications. This standard test development environment is used for many telecommunication applications. TTCN-3 benefits include:
- Commonly understood syntax and operational semantics unrelated to a particular programming language
- Test suite maintenance involves less effort than many proprietary development environment test suites
For users of Testing Technologies' TTWorkbench tool, Catapult now offers a TTCN-3 Adapter allowing TTCN-3 test scripts to run over the DCT2000. DCT2000 users connect to the system under test through the Ethernet interface. TTCN-3 scripts for conformance testing of VoIP and IMS are available from Testing Technologies including:
- SIP
- H.248
- SUA
- M3UA
- SCTP
- IPv6
The TTWorkbench tool and DCT2000 Adapter can also be used to write TTCN-3 test scripts for a wide variety of technologies and interface types.
For specific information on Testing Technologies' TTWorkbench tool, please refer to http://www.testingtech.de. For specific information on the TTCN-3 Adapter and its implementation with DCT2000 test systems, please contact your Catapult representative.
New m500 Processing Card Drives Higher Power, Capacity, and Versatility
Catapult now offers a five-processor mesh computing unit (mCU5) card to provide a significantly higher level of power and versatility. Supported on the m500 platform, the processing power of five communications processors combined with a total memory of 2.5 GB makes the mCU5 especially well suited for high performance load test applications. Users have experienced an increase in load capacity of 2.5 to 3 times the original mCU2 card. In specialized load tests, the mCU5 card provides an aggregate bi-directional throughput of 390 Mbps of ATM data and up to 622 Mbps of ingress ATM data, processing approximately 500,000 packets per second.
For more information on the new mCU5, please contact your regional Catapult representative.

DCT2000 Technical Tip
Defining Variables on the m500 mCU5
When using multiple processors on the mCU5, the context associated with each processor is labeled in launcher as context_1, context_2, and so forth. To define specific variables, use the context name. If defining global variables, there is no need to specify a context.
In the example below the variable context is the IP address for each of the five processors and is defined with the following notation:
Variable context processor 1: {ANTI_1}%Global_Data_server_ip ='66.174.95.91'
Variable context processor 2: {ANTI_2}%Global_Data_server_ip ='66.174.95.92'
Variable context processor 3: {ANTI_3}%Global_Data_server_ip ='66.174.95.93'
Variable context processor 4: {ANTI_4}%Global_Data_server_ip ='66.174.95.94'
Variable context processor 5: {ANTI_5}%Global_Data_server_ip ='66.174.95.95'
Configuring SS7 Links on J1/E1/T1 and Structured STM-1 Cards
The J1/E1/T1 PPCI card (JET) supports up to four J1/E1/T1 links while the Structured STM-1 cPCI card (SSTM) supports up to four physical optical links, each of which can support up to 63 E1s or 84 T1s multiplexed over each fiber. To configure the JET card, a physical link is selected to indicate the specific E1/T1 that will carry the SS7 signaling. On the SSTM card, the physical link is also selected; however, as each physical link is capable of carrying 63 E1s or 84 T1s, a further index is required to point to a specific E1/T1 that will carry the SS7 signaling.
The SSTM card has two index modes that breakdown the STM signal to a specific E1/T1: K-L-M or M-L-K mapping modes. K-L-M dereferences the STM signal by TUG3-TUG2-TU12/TU11 (E1/T1), a top-down approach, while M-L-K uses a bottom-up approach or TU12/11-TUG2-TUG3. Once the additional E1/T1 index is chosen on the SSTM card, the remaining configuration of the JET card and SSTM card is the same.
Please refer to the user guide/specifications for details on breaking down the STM signal tributaries.
