Characteristics

Standards

Functional
& electrical

G961 for operation in analysis or NT, LT simulation.
A POWER (or PWR IN) 2-pin connector enables the use of an auxiliary Power-adapter unit for the Clarinet interface to supply the PW1 signal when the selected operation is LT simulation.

Mechanical

2x ISO-8877 8-pin RJ45 connectors.

The two RJ45 connectors can be used for operation in analysis or simulation.

ISDN Mode

Connexion

Monitoring

Connection uses the serial mode with both connectors :
  • FROM LT (from line termination, ie network side)
  • FROM NT (from network termination, ie user side)

User Simulation

  • FROM LT connector

Network Simulation

  • FROM NT connector
