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. -
