Note: The circuits referenced in this section represent typical interfaces used in
telecommunications equipment. SIDACtor devices are not the sole components
required to pass applicable regulatory requirements such as UL 60950, GR 1089, or
TIA-968 (formerly known as FCC Part 68), nor are these requirements specifically
directed at SIDACtor devices.
