Overview
Thank you for choosing the Metrobility T3/E3 media converter.
The Metrobility T3/E3 media converter from Systems provides high-speed inte-
gration and conversion of T3 (44.736Mpbs) or E3 (34.368Mbps) coaxial telco com-
munication lines to ber transport environments. The copper data stream is converted
to optical signals for greater noise immunity and longer transmission. The T3/E3
model supports remote ber optic links up to 2km over multimode and up to 100km
over singlemode cable.
To optimize your T3/E3 network, this plug-and-play media converter operates

Follow the simple steps outlined in this section to install and start using your
Metrobility T3/E3 media converter.
Unpack the Media Converter and Accessories
Check that the following components have been included with your order:
• Metrobility T3/E3 media converter
• Power supply
• Power supply cord
• Four (4) rubber feet
Your order has been provided with the safest possible packaging, but ship-
ping damage does occasionally occur. Inspect your order carefully. If you
discover any shipping damage, notify your carrier and follow their instruc-
tions for damage and claims. Save the original shipping carton if return or
storage of the unit is necessary.
Choose an Appropriate Location
The Metrobility T3/E3 media converter is intended for use in either ofce or
industrial environments. The unit must be located within six (6) feet of the
AC power source being used and placed as far away as possible from elec-
trical noise generating equipment such as copiers, electrostatic printers and
other motorized equipment. If exposed twisted-pair wiring is used nearby,
the wiring should be routed as far away as possible from power cords and
data cables to minimize interference.
The unit may be oriented in any manner which permits the user to make
physical connection to the power supply and leaves a minimum of six (6)
inches of space for proper ventilation.
TUV Compliance Note: For pluggable equipment, the socket outlet must be
installed near the equipment and be easily accessible.

LBO Switch (functional only on T3 models)
Set the Line Build Out (LBO) switch down to support a long haul con-
nection if the length of your coaxial cable is between 255 and 1200 feet.
Set LBO up to support a short haul connection if the length of your coaxial
cable is less than 255 feet. The default setting is short haul.
CLP Switch
The Copper Loopback (CLP) switch enables/disables loopback on the cop-
per port. When copper loopback is enabled, the incoming data and clock
are looped from the RX copper port to the TX copper port, thus returning
the copper input back to the sending device. At the same time, the data is
transmitted to the remote T3/E3 unit. However, data from the remote unit
is ignored. Loopback is disabled by default. For more information, refer to
Loopback Modes in the User Guide section of this manual.
FLP Switch
The Fiber Loopback (FLP) switch enables/disables loopback on the ber
optic port. When ber loopback is enabled, the incoming data and clock are
looped from the RX ber port to the TX ber port. The data is also trans-
mitted to the copper port, however, data from the copper port is ignored.
Loopback is disabled by default. For more information, refer to Loopback
Modes in the User Guide section of this manual.

Set the Switches
A set of DIP switches is located on the back of the unit. On the T3 models,
functional switches are clearly labeled and allow you to select from several
modes of operation. On the E3 models, only the switches labeled CLP and
FLP are functional. Unmarked switches are inoperative.
NOTE: The switch is ON when it is in the DOWN position.
The switch is OFF when it is in the UP position.

Coaxial to Fiber Data Path
The receive (RX) port on the coaxial interface accepts an electrical signal. This
signal is coupled to the line interface unit (LIU) through a line transformer. The LIU
performs clock and data recovery and converts the signal into non-return to zero
(NRZ) data and clock. The NRZ data and clock then pass through the eld-program-
mable gate array (FPGA), which encodes the data for ber optic transmission. The
encoding ensures adequate transition density for reliable clock recovery at the remote
T3/E3 ber optic interface.
Fiber to Coaxial Data Path
The RX port on the ber interface accepts an optical signal from the remote T3/E3
unit and converts it back to an electrical signal. The optical signal rst enters the
voltage-controlled crystal oscillator (VCXO), which extracts the line rate clock and
data. The recovered clock and data are then sent to the FPGA for decoding. The de-
coded data stream goes to the LIU for encoding into T3 or E3 signals. The transmit-
ted signal is coupled to the BNC coaxial connector through a line transformer.
On both the RX and TX ports of the coaxial interface, surge protection is provided.
Timing Paths
The transmit (TX) and receive (RX) paths are clocked independently and during nor-
mal operation, the Metrobility T3/E3 units are never timing masters of the network
system. In the coaxial to ber path, timing is recovered by the unitʼs LIU and trans-
mitted over the ber line to the remote T3/E3 unit. In the ber to coaxial path, timing
is derived from the incoming optical signal and sent over the coaxial TX line.

The following examples show the status of the LK LED under various link condi-
tions and describe when unframed all ones are generated. (Loopback is disabled in
these examples.)
Note: An all-ones pattern indicates an alarm indication signal (AIS) for the E3 units
only. For T3 models, the all-ones pattern is simply transmitted to the remote device;
it does NOT indicate AIS.

Input Coaxial Link Loss
Loss of the copper input disables the BNC portʼs LK LED. It also forces the T3/E3
unit to generate unframed all ones (AIS for E3 only), which are transmitted out its -
ber port. For example, if the local unitʼs inbound coaxial cable breaks, it will transmit
all ones to the remote T3/E3 unit via the ber cable. The remote unit then carries the
pattern forward via its coaxial cable to the remote device.
Input Fiber Link Loss
Loss of the ber input is indicated by the ber portʼs unlit LK LED. When the ber
input is lost, an unframed all-ones pattern is transmitted from the coaxial port, as
shown in the following illustration.

Remote Coaxial Link Loss
Loss of link to the remote device produces a red alarm condition at the remote site
and should force the device to revert to its internal clock. If the remote device is
congured to send back a yellow alarm under this condition, the two T3/E3 units will
carry the alarm forward to the local device, as shown below.

Loopback Modes
The Metrobility T3/E3 media converter features two loopback modes to help verify
correct installation and to diagnose system problems.
Normal
During normal operation, without loopback, data from a local device (CSU, PBX,
etc.) enters the local T3/E3 unitʼs coaxial receiver, passes through the ber line be-
tween the two converters, then exits the remote unitʼs coaxial transmitter to enter the
remote equipment, and vice versa.
Loopback
Loopback helps to isolate and identify trafc problems within a specic segment.
During loopback, the yellow LBK LED is lit. Loopback is enabled/disabled by set-
ting DIP switch 2 or 3. Once loopback is enabled, the unit will remain in this mode
until the DIP switch is turned off.
Copper and ber loopback cannot be enabled at the same time. If both DIP switches
are enabled, only the rst one set will be in effect until it is disabled.
Copper Loopback
During copper loopback, timing and data received on the coaxial line are looped
back to the sending device. The loop occurs in the FPGA. The data is also
transmitted to the remote T3/E3 converter, but the data from the remote unit is
ignored by the converter in loopback mode.
In the example shown below, the local T3/E3 unit has copper loopback enabled.
Data received at the BNC port is simultaneously returned to the local device and
sent to the remote T3/E3 unit and on to the remote device. Data from the remote
device is transmitted by the remote unit, however, it is ignored by the local unit
at its ber optic interface.

Fiber Loopback
In this mode, the incoming data and clock on the ber line are looped back. The
loop occurs in the FPGA. The data is still sent out the coaxial transmitter. How-
ever, the data received at the BNC interface is ignored.
In the example below, the remote T3/E3 unit has ber loopback enabled. Data
received at the ber optic input is simultaneously returned to the local device
and sent to the remote device. However, data from the remote device is ignored
