Monitor Lines
To view real-time activity of the ISDN, T1, and E1 lines on the PortMaster, click Monitor==>Lines.
Select a line and use the Reset Counters button to restart incrementing values in PMVision only, not on the PortMaster. Use Restore Counters to restore these counters to their real-time values.
To view Lines simultaneously with other options in the
