DTM Series • T3/DS3/E3/STS-1 Tri-Port Transformer Modules
These modules contain both transmit and receive transformers
designed for use in in T3/DS3 applications using bit rates off
44.736Mbps, E3 interfaces at 34.368Mbps and STS-1
applications at 51.84 Mbps The transformers are typical for 75
ohm bandwidth applications requiring a very fast rise times.
