Status Monitoring

• Status of alarms on T1 Interface
• Status of the Ethernet Interfaces
• Monitoring data through put speed of the Ethernet Interfaces.

Programmable Features

• Telnet interface for remote programming and monitoring by using CLI text commands.

Applications

• 10/100 BaseT Ethernet to T1 Conversion (100BaseT over a T1 Interface).
• Bridging Ethernet LANs over existing TDM (T1) telecom network.
• Extending Ethernet networks utilizing TDM (T1) landline based telecom infrastructure.
• Using telecom network of T1/PDH/SDH microwave etc. carrying T1 to transport Ethernet data.

In all cases the equipment must be always installed and used in pairs, with one terminal being installed at either end of the network.
