The CCITT recommendations G.703 describe the physical and (XR6164, XR-T6165, and XR-T6166). The characteristics of
electrical characteristics of digital interfaces at 64 Kbps. these transformers allow the pulse to comply with the pulse
PE-65535 listed above has been designed for the codirectional
interface and matches the driver/receiver chips from EXAR
masks in the 120 Ω system.
