Black Box G703/V.35 manual Typical Application, Technically Speaking, Specifications

Typical Application:

Connect your Cisco routers’ X.21 interface to your 2 Meg leased line.

Technically Speaking:

The MicroConverter G.703 comes pre-configured for 75-ohm unbalanced operation. Connection to the 75-ohm unbalanced G.703/E1 network is achieved through connection using the two BNC connectors on the rear panel of the unit.

For use on a 120-ohm balanced service then the connections should be made using the RJ-45 connector on the rear panel of the unit. As the units’ default set-up is for 75-ohm, the correct setting should be made on the switch bank for 120-ohm balanced operation.

The data transmitted and received on the G.703 side of the MicroConverter G.703 could have originated on another piece of equipment. It is not uncommon for the data to be inverted by G.703 terminating equipment. The MicroConverter G.703 has the option to invert or not invert the data transmitted and received on the G.703 port.
