Transition Networks SCSCF30XX-10X Installation -- Continued, Set the Configuration Switches

SCSCF30xx-10x

Part Number	Port One - Copper	Port Two - Single Fiber Optic
SCSCF3029-102	75 ohm coax (BNC)	SC, 1310 mn (TX)/1550 nm (RX)
		40 km (24.8 miles)*
SCSCF3029-103	75 ohm coax (BNC)	SC, 1550 mn (TX)/1310 nm (RX)
		40 km (24.8 miles)*

SCSCF3029-102 and -103 are intended to be installed in the same network where one is the local converter and the other is the remote converter.

SCSCF3039-100	75 ohm coax (BNC)	LC, 1300 mn multimode
		2 km (1.2 miles)*

*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 Device.

Set the Configuration Switches

The configuration switches are located on the side of the Device. Use a small, flat- blade screwdriver to set the recessed switches.

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

E3

	15 x 5 in. (432 x 381 x 127 mm)
WMBL	Optional Wall Mount Brackets; 4.0 in. (102 mm)
WMBV	Optional Vertical Mount Bracket; 5.0 in. (127 mm)
WMBD	Optional DIN Rail Mount Bracket; 5.0 in. (127 mm)
WMBD-F	Optional DIN Rail Mount Bracket (flat); 3.3in. (84 mm)

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	FL
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.

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).

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).
