Details

Make bidirectional G.703 balanced and unbalanced conversions and protect against ground loops.

Use G.703 75–120 Adapters to connect your G.703 network to your shielded twisted-pair equipment.

These adapters address the open network provision (ONP) requirement that European post, telephone, and telegraph (PTT) authorities offer 120-ohm twisted-pair terminations to their customers.

Use the adapters to convert the balanced G.703 signals from your bridges and routers to unbalanced G.703 signals. So you can use your 75-ohm coax hardware and communicate with 100-ohm or 120-ohm twisted-pair equipment. The adapters convert signals bidirectionally, too.

Setup is super easy. Just plug in the adapters. If needed, you can configure the shield connection between the 75-ohm and twisted-pair interfaces.

The G.703 75–120 Adapters support E1 data rates to 2.048 Mbps. For sending TX and RX signals over STP cable, order the MT256A-F, which has 1.6/5.6 dual-coax connectors.

The G.703 75–120 High-Speed Adapters support data rates to 8 Mbps.
