Timing; Ground Fault Detect - ADC HiGain H2TU-C-202 User Manual

Appendix B - Functional Operation
T
IMING
The low loop wander (0.3 UI max) of an H2TU-C, when used with compatible regenerators and remote units,
allows the circuit to be used in all critical timing applications, including those that are used to transport Stratum 1

timing.

G F
ROUND AULT
The H2TU-C has a Ground Fault Detect (GFD) circuit which detects a ground or a resistive path to ground on any
wire of the HDSL2 loop.
This makes the product compliant with the Class A2 requirements of GR-1089.
