The transformers have been developed for use as 4. Optional Tape & Reel packaging can be ordered by transmit and receive transformers in T3 or DS3 links, using adding a T suffix to the part number (i.e. T323NL T). bit rates of 44.736Mbps and B3ZS coding on coaxial cable. The characteristics allow compliance with the Pulse 5. For other T3/DS3/E3/STS-1 Transformers, please see templates of CCITT G.703 as well as ATT.A.34. The data sheets T606, T672, T663 and T668. transformers are also suitable for E3 interface at 34.368Mbps with HDB3 coding or STS-1 applications, at 6. Transformer Selection Guide - Please contact Pulse 51.84Mbps according to Bellcore TA-NWT-000253. Applications Engineering or see the Pulse web site Data Sheet Menu to find the latest Transformer Selection 2. Bandwidth specifications are typical in a 75 system. Guide. Return loss meets the requirements of G.703. Materials used in the products are UL94-V0 recognized. Products meet the requirements of IEC 695-2-2 (Needle Flame Test). 3. For those applications requiring a 1:1 turns ratio on the transmit side, use only half of the secondary (2CT) winding.
