Telecommunication Division
Developing and providing software for
•Network-wide Monitoring Systems
•Telecommunications Traffic Analysis
•Application Gateways & Service Logic
•Fraud Detection Systems
•Short Message (SMS) Handling

•Location Based Services
•Missed Call Notifications
•EIR: Equipment Identity Register
Interface cards
Based on in-house developed cards:
• 2x2 (1.5) Mbps PDH (E1/T1)
• 2x155 Mbps SDH/SONET and ATM
• 4x100 BaseT, copper
• 4x1000 BaseT, fiber, copper
Utilizing L2 and L3 technologies:
• SS7 MTP
• HSL - many - e.g.30 links bundled
• MTP3b, AAL-5
• Ethernet, SIGTRAN, ATM
The Present
Our Passive
Monitoring Systems in Use
for 1…10 years
SS7 & GPRS monitoring to cover complete networks
 analyzes and stores traffic and call data (30 million
calls/day)
 creates statistics and debug info
 real-time call tracing
 filtering fraudulent calls
 right tool for handling customer complaints
Gigabit EthernetMonitoring
 monitoring Tbytes of data for traffic analysis
 to detect bottlenecks and other traffic problems
 on-line filtering and off-line processing software

The Future
Aims
To develop a multipurpose board for NGN networks as a
monitoring and data-processing unit with
•
•
•
•
very high performance
low power consumption
high scalability
composability
Hardware Architecture of C-Board
2x10 Gbit/s --- 8…16x0.1…3.5 Gbit/s
Foreseen Main Applications
for the C-Board
• Measuring traffic mix
• Deep packet inspection
• IMS SIP platform (IP Multimedia Subsystem, Session
Initiation Protocol)
• Routing at Layer 2, Layer 3, GMPLS (Gigabit
Multiprotocol Label Switching)
• Video transcoding
• Media Gateway
• Firewall
• Traffic generator
