2.0 PRODUCT DESCRIPTION

The Patton Model 460 Series enables 75-ohm coax hardware to com- municate with 120-ohm twisted-pair equipment. The Model 460 Series specifically address the ONP requirement that European PTTs offer 120- ohm twisted-pair terminations to their customers. Some PTTs and pri- vate carriers are standardized on 75-ohm coax, or have customers whose CPE has only 75-ohm coax connections. The Model 460 Series provide a ready solution to this termination mismatch by allowing a bi- directional conversion of coax (75 ohm) to a twisted-pair (120-ohm), sup- porting data rates to E1 (2.048 Mbps). The signals output by them are scaled to match the pulse shape requirements specified by the CCITT G.703 standard.

The Model 460 is available in the following versions:
