... Dual SMT, Extended Temperature Range Application Notes 1. The transformers have been developed for use as transmit and receive transformers DS3 links, using bit rates of 44.736Mbps and B3ZS coding on coaxial cable. The charac- teristics allow compliance with the pulse templates of CCITT G.703 as well as ATT T.A.34. The transformers are also suitable for the E3 interface at 34 ...
