AT310XS Series

The AT310XS series of transformers was developed to be

used for T3 or DS3 links as either receive and transmit

transformers.

These transformers carry bit rates of 44.736 Mbps and B3Zs

coding schemes on coax cable. It complies with the pulse

templates of CCITT G.703 as well as ATT T.A.34. Because of

its high bandwidth, these transformers are also suitable for

E3 interface at 34.368 Mbps with HDB3 coding and even

finding applications in the STS-1 at 51.84 Mbps.

The operating temperatures of these transformers meet

industrial standards of -40° C to +85° C.
