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.
