omnitron-systems-technolo iconverter t1-e1 User Manual

The 

 T1/E1 media converter provides standard T1 (1.544Mbps) or E1

(2.048Mbps) copper to fiber conversion and can be used to extend the demarcation
point between service provider and networking equipment. T1/E1 media converters
operate in pairs, extending distances over fiber, which improves noise immunity, quality

of service, intrusion protection and
network security.

The T1/E1 supports Small Form
Pluggable (SFP) transceivers,
enabling adaptability to different fiber
types, distances and wavelengths,
providing maximum flexibility across
a variety of network architectures and
topologies.

1) Configure DIP-Switches

2) Install Standalone Module and Connect Cables

3) Verify Operation

When this DIP-switch is set to the “Loop” position, it sets the

 iConverter 

T1/E1 converter

to a dual loop-back mode (see Figure
B) on both the fiber and copper
connections. By returning the DIP-
switch to the “Norm” position, the unit
resumes normal operation.

This DIP-switch will allow the entire
fiber segment to be tested at either
of the 

T1/E1 converters

without having to set DIP-switches
on both units.  When this DIP-switch
is set to “FOT”, the local unit (the unit
with the DIP-switch in the “FOT”
position) is switched into local loop-
back mode.  In addition to the local loop-back mode of operation, the fiber TX port is
further encoded to carry a remote loop-back protocol. This remote loop-back protocol
sets the remote unit at the other end of the fiber link to a remote loop-back mode of
operation and returns a signal to the local unit (see Figure C).  A fast blinking “Tst” LED
on the local unit and a slow blinking “Tst” LED on the remote unit shows confirmation
that the fiber segment is communicating properly between devices.  By returning the
DIP-switch to the “Norm” position, the units resumes normal operation.

c. Connect to the RJ-45/48 connector on the 

 T1/E1 converter via a Category 3

or better cable (Category 5 is recommended), and attach the other end to the network
equipment.

d. Connect an appropriate multimode or single-mode fiber cable to the fiber port of

the installed module. It is important to ensure that the transmit (TX) is attached to
the receive side of the device at the other end and the receive (RX) is attached to
the transmit side. Single-fiber (SF) media converter models operate in pairs.  The
TX wavelength must match the RX wavelength at the other end and the RX
wavelength must match the TX wavelength at the other end.

Once the module has been installed and configured per steps 1 and 2, verify the
module is operational by viewing the LED indicators.

The Power LED indicates the module is receiving power.

The Fiber Optic link LED indicates the fiber optic connection has been established.

The UTP LED indicates a T1/E1 signal has been detected.

If the Fiber Optic LED is blinking, the port is receiving an all 1s signal.  This will occur
if the UTP port is not connected.
