User’s Guide
SCSCF30xx-10x
Stand-Alone Media Converter
• DS3 or T3 / E3
• Coax (BNC) to Fiber
Transition Networks SCSCF30xx-10x series
media converters encode and decode DS3 or
E3 coax copper signals over fiber optic cable
to extend the distance and transmission
reliability of high-speed DS3 or E3 data traffic.
The SCSCF30xx-10x also connects remote
locations via T3/E3 cable.
NOTE: The CCSCF30xx-10x model is the
chassis version of the media converter. For
more information, see the CCSCF30xx-10x
user’s guide on-line at www.transition.com.

CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the jumper. Failure to observe this caution could result
in damage to, and subsequent failure of, the media converter.
Set the Coax Grounding Jumpers
NOTE: Modify the settings for J11 and J12 only if necessary.
Jumpers 11 and 12 (located on the circuit board near the coax ports) provide a
grounding feature so that the SCSCF30xx-10x media converter complies with
the G.703 specification where:
• The output coax port is connected to chassis ground.
• A provision to connect the input coax port to chassis ground is provided.
The factory settings for these two jumpers are:
Jumper 12 (jumpered) = Output coax port is connected to chassis ground.
Jumper 11 (not-jumpered) = Input coax port is not connected to chassis ground.
The jumpers are located on the circuit board inside the media converter
housing. To set the jumpers:
1. Using a small screwdriver, remove the four (4) screws that secure the cover
and carefully remove the cover from the media converter.
2. Locate the jumper on the circuit board.
3. Using small needle-nosed pliers or similar device, move the jumper to the
desired position. (Refer to the above drawing.)
4. Carefully replace the cover on the media converter and replace the four (4)
screws that secure the cover to the media converter.
