There are twelve LEDs on the DSU/CSU front panel. The five LEDs on the right

interface and the data ports. Refer to Selecting the DTE Drop/Insert or Data Port
for LED Display on page 3-12 to choose which port’s status the LEDs display.
NOTE:
The DTE Drop/Insert (DSX-1) interface is only available on 2-port and 4-port
DSU/CSUs.
