General description
Functional
The 21-180, Fiberoptic G.703 converter is intended to extend distance and galvanic
isolate the teleprotection equipment for substations connection to telecom network.
Fiber Optic G.703 Codirectional
The ITU-standard “G.703 64kbit/s codirectional interface” describes a galvanic
interface. This interface is for example commonly used by teleprotection equipment
for connection to telecom multiplexers.
The codirectional interface is transferred at one balanced pair for each direction.
21-180
The 21-180 converts the codirectional interface signals to a proprietary fiber optic
protocol.
Applications
The fiberoptic port of the ABB REL55x/56x , Line Differential Protection
Terminals, is directly connected to the fiberoptic port of 21-180. The 21-180 Codir-
port is then connected to a 2048kbps G.703 E1 multiplexer.

Mounting
Before mounting check if 21-180 must be configured internally. See later in this
chapter under section “Signal ground - Protective earth/ground”.
The products can be used stand alone, rack mounted or attached with screws to wall
or similar.
The rack brackets have two alternative places on each side of the unit and the
brackets can be rotated for alternative positions.

shielding around each pair and a braid shielding around cable).
Fiber Optic Port.
The fiber optic connector is of ST type.
Confirm that the attenuation of the fiber optic cable, including splices and patch
cables, doesn’t exceed the system budget. Don’t forget to add a safety margin.
Minimum safety margin is 3dB.
Make sure that the local fiber optic transmitter, marked Tx, is connected to the
remote units fiber optic receiver, marked Rx. And local Rx shall be connected to
remote Tx.

Configuration
Normal use
Normally no configuration is needed!
When two 21-180 are connected back-to-back, (G.703 Codir ports connected to each
other), one of the 21-180 should be set to “Internal Clock”.
Config rotary switch
Configuration switc
h
The rotary switch has 16 positions, (HEX-switch).
At position 0 the switch’s arrow, visible through the adjusting hole, points straight
down.
All configuration is done by setting the position of the “Config” rotary switch on the
frontpanel. The “Config”-switch is operated with a small screwdriver. The switch has
16 positions. Every switch position is presented by the four LEDs 1, 2, 4 and 8. The
LEDs forms a corresponding binary-value of the switch position.
In the table below an “X” marks a lit LED.

External clock
When HEX-switch is in position 0, the clock extracted from the signal received at the
G.703 64kbps Codir port is used. This is the normal configuration when connected to
a telecom network.
Fiber clock.
When HEX-switch is on position 1, the clock used is regenerated from fiber optic
interface. This can be used for example when G.703 Codir needs to be galvanic
isolated.
Internal clock – “Master mode”
When HEX-switch is on position 2, the clock used is generated by an internal clock.
This is for example used when two 21-180 are directly connected to each other with
galvanic cables. Only one 21-180 shall have this configuration.
15

Start and usage.
Power on.
Connect the power cord to the 21-180 and then connect to a power supply with PE,
(Protective Earth/ground connection).
The “LO”-LED shall be lit green. If not, try to cross-connect the fibers at one end of
the link.
LED-status.
There are 12 LED-indicators at the front panel.
Power
A green LED lit, within 5 seconds, when power is connected to the unit.
Link
A green LED lit when G.703 Codir interface receives correct coded G.703 Codir
signal.
16

1 , 2 , 4 , 8
Yellow LEDs. Marks the position of the Config switch. The four LEDs forms a
binary value, lit LEDs, corresponding to the 16 positions of the Config switch. Only
position 0, 1 and 2 of the configuration switch are used. LEDs 4 and 8 shall always be
“black”.
MLA
Memory Local Alarm. Normally off/dark. This indication has the same function as
“LA” with an additional memory function. Is lit red if the unit has detected an “LA”-
error, and stays lit until the “Reset”-button is pressed.
MRA
Memory Remote Alarm. Normally off/dark. Is red if when the remote unit of the
fiber optic link has detected an error. This indication has a memory function. Any
remote error will be indicated until “Reset”-button is pressed.
TXD
A yellow LED indicates data sent at selected electrical interface.
RXD
A yellow LED indicates data received at selected electrical interface.
LA
Local Alarm. Normally off. Is lit red if the fiber optic link monitoring has detected a
communication error on the incoming fiber.
LO
Link OK. Green when the fiber optic link is operating correctly.
