4.5  External Connections 

External connections to the G1IF1 are shown in section 3.2. There are three types of connection 
to the unit. 

The fibre optic connections are made with standard ST type connectors. Transmitters are of the 
LED type. When handling fibre optic cables, care should be taken so as not to cause damage by 
rough treatment or by exceeding the minimum bend radius of the fibre. 

The CCITT G703 interface connection is made with a ring terminal block labeled TB1. The X.21 
interface connection is made with a standard 15-way DIN type connector. 

The power supply and safety earth connections should be made with ring-type crimp terminals to 
the terminal block TB1.
