LSM 2005

Loop Switching Module - DSL Test RobotLSM 2005

Switch copper lines carrying xDSL signals.

Automatically configure LSX line segments according to either a user or one of the Standards configurations.



Up to 4 LSX Line Simulator Segments can be connected to a single LSM unit.  Up to 2 LSM units can be cascaded into a single test platform.  This provides the ability to create any loop configuration containing up to 8 segments (Bridged Taps or Loops). 

Each LSM can be optionally equipped with an Arbitrary Noise Generator (ANG). Both cascaded LSM units can be equipped with a built-in ANG to provide for identical noise characteristics for HDSL or BONDING testing.
Additionally a card with multiple Bridged Taps can be built into the LSM.

With the combination of the LSM, ANG and ICL-Server, one can build a fast and fully automated xDSL test platform.   

Seamless Integration
The LSM is designed to ensure seamless integration of the Sparnex LSX Suite for physical layer testing, using the customers’ existing test equipment for traffic generation, protocol testing and throughput verification.
