Overview  

The Patton Model 463 is a miniature G.703 balun that allows 75-ohm coax hardware to communicate with 120-ohm twisted-pair equipment.

The Model 463 specifically addresses the ONP requirement that European PTTs offer 120-ohm twisted-pair terminations to their customers. Some PTTs and private carriers are standardized on 75-ohm coax, or have customers whose CPE has only 75-ohm coax connections. The Model 463 presents a ready solution to this termination mismatch. Supporting E1 data rates to 8 Mbps, the Model 463 receives 75-ohm signals and converts them to 120-ohm for transmission over a network or reception by a CPE (see diagram below). The signals output by the Model 463 are scaled to match the pulse shape requirements specified by the CCITT G.703 standard.

The Model 463 can perform 120-ohm to 75-ohm signal conversion as well, giving the device a dual role.
