Front Panel LEDs
The front panel provides eight status LEDs to monitor operation and activity. The LED functionality
varies based on product and software load (TDM versus ATM). Table 3 provides LED descriptions for
Total Access 604/608 systems employing TDM software, and Table 4 on page 26 lists ATM software LED
functionality.
