We provide monitoring solutions for different types of physical interfaces
and for decoding many different protocols at a single interface, thanks
to the multi-user and multi-interface capabilities of the LSU product
family.
This leads to significant cost advantages and highly flexible solutions
for applications such as Protocol Analysis
in the lab or field, as a Statistical Tool
for the analysis of large logs and KPI extractions, and for Monitoring
Probes during live network operations.
E1/T1 Interface
E1/T1 lines are monitored by dedicated PCM cards:
signaling protocols for GSM/GPRS/EDGE networks
TRAU frames and PCU frames
ATM - IMA for UMTS networks
STM-1/OC-3 Interface
STM-1/OC-3 interface is monitored by a dedicated cards with connectors
for both optical and coaxial links:
ATM cells for UMTS networks and high speed data backbones
SDH frames carrying 63 channelized E1 for each STM-1 line
Gigabit Ethernet
Gigabit Ethernet connections are monitored by dedicated switches:
ATM cells for communication between UMTS network elements
IP traffic for GPRS/EDGE/UMTS Core Network
Wi-Max technology
LSU Interface Scalability
The Line Server Unit (LSU) and the dedicated
Network monitoring Probe Unit (NPU) equipment can
acquire and log data from practically all the communication interfaces
used today in mobile telephony networks.
The LSU product family is made by 3 different models from the most powerful
in terms of number of lines and processing power to the smallest and portable
one used to monitor only a few lines directly on the field.

Typical Monitoring Installation Example
Multi-user and multi-interface support
The LSU platform is dedicated to protocol management relating to timing
constraints of real network elements under test. The protocol decoding
is executed by external client applications.
This provides the following unique benefits:
Monitoring of multiple interfaces and channels in parallel
Multiple users can access the monitoring facility through the LAN
Open interface
The monitoring interface between the LSU system and the client application
is open to our customers, allowing them to develop their own dedicated
software for data acquisition and post processing.
High connectivity and processing power
High connectivity and processing power allow monitoring of complex interfaces
(like EDGE Abis) and high-speed interfaces (like STM-1).
Unique capabilities
The LSU architecture allows the gathering of data from multiple interfaces
with a time-stamp mechanism that identifies the slightest gaps. As a result,
traffic flows coming from different interfaces can be analyzed together
to offer a complete and coherent view. An innovative labeling mechanism
provides the basis for a flexible and intuitive call tracing facility.
