CCSCF30xx-10x
24-hour Technical Support: 1-800-260-1312 -- International: 00-1-952-941-7600
* Typical maximum cable distance. Actual distance is dependent upon the
physical characteristics of the network. (TX) = transmit (RX) = receive
** CCSCF3029-100 and -101 are intended to be installed in the same network.
*** CCSCF3029-102 and -103 are intended to be installed in the same network.
Part Number Port One - Copper Port Two - Single Fiber Optic
CCSCF3029-101 ** 75 ohm coax (BNC) SC, 1550 nm (TX)/1310 nm (RX)
single mode, 20 km (12.4 miles)*
CCSCF3029-102 *** 75 ohm coax (BNC) SC, 1310 nm (TX)/1550 nm (RX)
single mode, 40 km (24.8 miles)*
CCSCF3029-103 *** 75 ohm coax (BNC) SC, 1550 nm (TX)/1310 nm (RX)
single mode, 40 km (24.8 miles)*
CCSCF3039-100 75 ohm coax (BNC) LC, 1300 nm multimode, 2 km
(1.2 miles)*
Installation
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the jumpers. Failure to observe this caution could result
in damage to, and subsequent failure of, the media converter.
Set the Hardware/Software Jumper (J3)
The hardware/software jumper is located on the circuit board of the media
converter. Use a small needle-nose pliers or similar device to move the jumper
to the desired position.
Hardware The media converter mode is determined
by the switch settings.
Software The media converter mode is determined
by the most-recently saved, on-board
microprocessor settings.
Set the Coax Grounding Jumpers (J11 & J12) (Optional)
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 CCSCF30xx-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.

Switch 2 -- Coax Line Build Out (DS3 only)
up - The DS3 line is set up to operate at distances up to
225 ft. (68.6 m).
down - The DS3 line is set up to operate at distances
greater than 225 ft. (68.6 m).
< 225 ft. (68.6 m)
> 225 ft. (68.6 m)

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 media
converter.
Set the Configuration Switches
The configuration switches are located on the media converter circuit board.
Use a small, flat-blade screwdriver to set the recessed switches.
Switch 1 -- Select DS3 or E3
up - Supports a DS3 interface.
down - Supports a E3 interface.

Switch 3 -- Signal on Loss of Carrier
up - Transmits an alarm indication signal (AIS) on the loss
of the input carrier (unframed).
down - No signal is transmitted on the loss of the input
carrier (unframed).

Switch 4 -- Alarm Indication Signal (AIS)
up - AIS is defined as a pattern of alternating 1’s and 0’s
(unframed).
down - AIS is defined as a pattern of all 1’s (unframed).
Alarm = 1's and 0's
Alarm = all 1's
