S4TEF10xx-11x
Stand-Alone Media Converter
• Twisted-Pair Copper to Fiber
• 10/100Base-TX to 100Base-FX
• RS-232 to Fiber
• (4) T1/E1 to Fiber
The S4TEF10xx-11x media converter is
designed to extend signals from a 10Base-T
Ethernet/100Base-TX Fast Ethernet port, an
RS-232 data port, and up to four (4) T1/E1
network ports over fiber. The Ethernet, 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-11x is designed to be installed in pairs. For example, install one
S4TEF1011-110 as the local media converter and another S4TEF1011-110 as the remote
media converter. All S4TEF10xx-11x models have the following copper connectors.

to be installed in pairs, where one is the local converter and the other is the
remote converter.

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 T1/E1 loop-back test
scenarios are described in detail in under Troubleshooting, on page 24.

Switch set #2 - serial and ethernet options
6 - Twisted-pair Auto-Negotiation
Up (Enabled) - The media converter “advertises”
ALL rate and mode capabilities to the network:
• 100 Mb/s full- or half-duplex
• 10 Mb/s full- or half-duplex
The media converter brings up the Ethernet link to
the highest speed and mode possible for all the
attached network devices.
When selected, Auto-Negotiation allows a twisted-pair link to become operational only
after the Auto-Negotiation function matches network speed capabilities at both ends of
the twisted-pair copper segment.
down (Disabled) - The bridging media converter does not “advertise” the rate and
mode capabilities to the network. Switch 7 and switch 8 are then used to set the speed
and mode for the Ethernet link.
Note: Switch 7 and 8 are inactive if switch 6 is enabled (up).
7 - Ethernet speed
up (100Base-TX) - Sets the Ethernet port to
100Base-TX (100 Mb/s).
down (10Base-T) - Sets the Ethernet port to
10Base-T (10 Mb/s).
8 - Ethernet node
up (Full-Duplex) - Sets the Ethernet port to full-duplex mode. The twisted-pair cable
distances are constrained by the cable requirements (see pages 1 and 2 for the cable
specifications for the various S4TEF10xx-11x models).
down (Half-Duplex) - Sets the Ethernet port to halfduplex mode. The twisted-pair cable distances are
constrained by the 512-bit rule:
In a half-duplex network, the maximum cable
lengths are determined by the round trip delay
limitations of each Fast Ethernet collision domain.
(A collision domain is the longest path between any
two terminal devices, e.g. a terminal, switch, or
router.)
The 512-bit rule determines the maximum length of cable permitted by calculating the
round-trip delay in bit-times (BT) of a particular collision domain. If the result is less
than or equal to 512 BT, the path is good.
For more information on the 512-bit rule, see the white paper titled “Collision
Domains” on the Transition Networks website at: www.transition.com.

Disable Link Pass-Through
The Transparent Link Pass-Through feature allows the media converter to monitor the
Ethernet copper RX (receive) ports for loss of signal. For example, when the Ethernet
copper link on the near end device is lost (1), the local media converter transmits a
signal to the remote media converter (2), thus, “passing through” the link loss. The
remote media converter disables the Ethernet copper link to the far-end device (3),
which prevents the loss of valuable data unknowingly transmitted over an invalid link.
It is important to remember that, although the Ethernet copper link has been disabled,
the fiber link is still valid (4). Thus, there is no disruption to the transfer of T1/E1 or
RS-232 data signals over the fiber link.

Installation — Continued
Hardware/software jumper
The jumper is located on the circuit board, inside the media
converter housing.
Hardware:
The media converter mode is determined by the switch
setting (see pages 3 - 7).
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 jumper near the back end on the upper circuit board.
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.
Install the T1/E1 cable
1. Locate or build ITU-compliant copper cable with straight-through RJ-48
connectors installed at both ends. (See pages 19 thru 21 for the proper cable
specifications for your network application.).
2. Connect the RJ-48 connector at one end of the cable to one of the T1/E1 ports
on the S4TEF10xx-11x media converter.
3. Connect the RJ-48 connector at the other end of the cable to the T1/E1 port on
the other device.
