2.0 PRODUCT DESCRIPTION

The

Patton Model 460 Series

municate with 120-ohm twisted-pair equipment. The Model 460 Series
specifically address the ONP requirement that European PTTs offer 120­ohm 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 460 Series
provide a ready solution to this termination mismatch by allowing a bi­directional conversion of coax (75 ohm) to a twisted-pair (120-ohm), sup­porting 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:

• 460F

– A shielded RJ-45 jack.
– Two female coaxial connectors

• 460M

– A shielded RJ-45 jack.
– Two male coaxial connectors

enables 75-ohm coax hardware to com-

• 460F-TBP

– A 4-position terminal block.
– Two female coaxial connectors

• 460M-TBP

– A 4-position terminal block.
– Two male coaxial connectors

• 460MC

– A shielded RJ-45 jack.
– Two 6-in. coaxial cables with male connectors
