PRODUCT DESCRIPTION
The Patton Model 460 Series allow 75 Ohm coax hardware to
communicate 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 private carriers are standardized on 75 Ohm coax, or have
customers whose CPE has only 75 Ohm coax connections. The Model
460 Series present a ready solution to this termination mismatch by
allowing a bi-directional conversion of coax (75 Ohm) to a twisted pair
(120 Ohm ), supporting data rates to E1 (2.048 Mbps). The signals
2
output by them are scaled to match the pulse shape requirements
specified by the CCITT G.703 standard.
The Model 460s come in the following versions (see below):
460
· A shielded RJ-45 jack.
· 460M:Two male coaxial connectors (i.e., center conductor is
a pin).
· 460F:Two female coaxial connectors (i.e., center conductor is
a receptacle).
460-TBP
· A 4-position terminal block.
· 460M-TBP:Two male coaxial connectors (i.e., center
conductor is a pin).
· 460F-TBP:Two female coaxial connectors (i.e., center
conductor is a receptacle).
460MC
· Two male coaxial connectors at the end of a coax pigtail
cable. (i.e., center conductor is a pin).See photo on front
cover of manual.
