The S4TEF10xx-10x media converter can
extend signals from an RS-232 data port and
up to four (4) T1/E1 network ports over fiber.
The RS-232 and T1/E1 interfaces are independent of each other and the signals
from these ports can be sent over the fiber interface simultaneously.
The S4TEF10xx-10x is designed to be installed in pairs. For example, install one
S4TEF1011-100 as the local media converter and another S4TEF1011-100 as the
remote media converter.
All S4TEF10xx-10x models have the following copper connectors:
Connector TypeNumberDescription
RS-232 one (1)6-pin, DIN serial, 3.2 m (10 ft.)*
T1/E1four (4)RJ-48
The various fiber connectors are available on separate models. Both duplex and
single mode fiber optic converters are available:

S4TEF1018-100MT-RJ, 1300 nm multimode, 2 km (1.2 miles)*
S4TEF1029-10x(single mode, single fiber models are listed on page 2)
* Typical maximum cable distance. Actual distance is dependent upon the
physical characteristics of the network.
The chassis version of the media
converter is C4TEF10xx-10x. For more

Switch Set #1 - T1/E1 Options
5, 6, 7, 8 - Loop-Back Settings
The loop-back setting is used for installation and network debugging procedures.
Each of the T1/E1 ports can be individually set for loop-back mode:
• Switch 5 controls T1/E1 port 1 • Switch 6 controls T1/E1 port 2
• Switch 7 controls T1/E1 port 3 • Switch 8 controls T1/E1 port 4
When the loop-back switch for a particular T1/E1 port is enabled, the port loops
the signal from the receive port back to the transmit port. The loop-back test
scenarios are described in detail on page 16.

4. Enable / Disable Parity
When parity is enabled, an additional bit is added to
the 8-bit signal to identify whether the signal is sent
successfully. Use switch 5 to send odd or even
signal parity.

Hardware/Software Jumper
The hardware/software jumper is inside the media converter housing and is
located near the back end of the upper circuit board.
Hardware The media converter mode is determined by
the switch settings (see pages 3 - 6).
Software The media converter mode is determined by
the most-recently saved, on-board
microprocessor settings.
To set the jumper:
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 hardware/software jumper.
3. Using small needle-nosed pliers or similar
device, move the jumper to the desired position
(see above).
4. Carefully replace the cover on the media
converter and replace the four (4) screws that
secure the cover to the media converter.
Power the Media Converter
1. Connect the barrel connector on the power adapter to the media
converter’s power port (located on the back of the media converter).
2. Connect the power adapter plug to AC power.
3. Verify that the media converter is powered by observing the illuminated
LED power indicator light.
NOTE: For DC power, consult the user’s guide for the Transition Networks
SPS1872-xx DC external power supply.
