User’s Guide
SCSCF30xx-10x
Stand-Alone Device
• DS3 or T3 / E3
• Coax (BNC) to Fiber
Transition Networks SCSCF30xx-10x series
Devices encode and decode DS3 or E3 coax
copper signals over fiber optic cable to extend
the distance and transmission reliability of highspeed DS3 or E3 data traffic. The SCSCF30xx10x also connects remote locations via T3/E3
cable.
Note: The CCSCF30xx-10x model is the
chassis version of the Device. For more
information, see the CCSCF30xx-10x user’s
guide on-line at www.transition.com.

Installation
Set the Loop-Back Switch
The loop-back switch is located on the front panel of the Device and is used for
installation and network debugging procedures.
To set the switch, use a small flatblade screwdriver or a
similar device (see the drawing to the right).
CL (Coax loop-back) Enable loop-back on the local coax interface.
-- (Center Position) Normal operation.
FL (Fiber loop-back) Enable loop-back on the local fiber interface.
Note: Three loop-back test scenarios are described in detail on page 10.

CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the configuration switches. Failure to observe this caution
could result in damage to, and subsequent failure of, the Device.
Set the Configuration Switches
The configuration switches are located on the side of the Device. Use a small, flatblade screwdriver to set the recessed switches.
Switch 1 -- Select DS3 or E3
up - Supports a DS3 interface.
down - Supports a E3 interface.

Installation -- Continued
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 Device.
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 Device 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 Device 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 Device.
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 Device and replace the four (4) screws that
secure the cover to the Device.
