TRFOT-3 FEATURES

LANVIEW LEDs

 

Cabletron Systems’ LANVIEW Status Monitoring and Diagnostics 
System is a convenient troubleshooting tool that helps you diagnose 
physical layer problems. The front panel LANVIEW LEDs alert you to 
power failures, cable faults, and link problems.

 

Connectivity

 

The TRFOT-3 is equipped with single mode ST connectors for fiber 
links and a DB9 connector for copper links. The TRFOT-3 supports 
cable distances of up to 10 km over single mode fiber optic cable. You 
can attach the TRFOT-3 at either end of a fiber link.

 

Ring Speed Compatibility

 

The TRFOT-3 supports both 4 and 16 mb/sec ring speeds and senses 
the ring speed automatically.
