* Typical maximum cable distance. Actual distance is dependent upon the

physical characteristics of the network. (TX) = transmit (RX) = receive

Installation -- Continued

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.

**	CCSCF3029-100and -101 are intended to be installed in the same network.
*** CCSCF3029-102and -103 are intended to be installed in the same network.

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.

Switch 1 -- Select DS3 or E3 up - Supports a DS3 interface. down - Supports a E3 interface.

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).

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.

J11	J12
not jumpered	jumpered

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).
