Connecting the cables
2-4
DSLPipe DSU (SDSL) User’s Guide
Table 2-2 shows the proper setting for each configuration
.
Connecting the cables
To connect your DSLPipe DSU:
1
Use the V.35 to DB-25 cable to connect the V.35 device to the DSLPipe 
DSU.
2
Use the WAN cable to connect the DSLPipe DSU to the SDSL line. 
3
Use the power supply cable to connect the DSLPipe DSU to a power source. 
Plugging the power supply automatically turns on the DSLPipe DSU.
Checking the activity of the LED lights
To verify that your DSLPipe DSU is connected properly, observe the activity 
pattern of the lights at the front of the unit (see Figure ). When all the cables are 
connected, verify that:
The 
con 
light is on initially and then turns off. It blinks if there are any 
SDSL errors.
The 
wan
 light turns on after the 
con
 light turns off. It blinks until a 
connection is established, and then remains on.
The
 lnk
 light is on if the DSR (Data Set Ready) or the RTS (Request To 
Send) control on the V.35 port is active.
The 
act 
light blinks when there is any DSL activity, but it remains off 
otherwise.
The 
pwr 
light comes on and remains on.
