Non-AGTL+ Signal Quality Specifications and Measurement
Guidelines
Guidelines
There are three signal quality parameters defined for non-AGTL+ signals: overshoot/undershoot,
ringback, and settling limit. All three signal quality parameters are shown in
ringback, and settling limit. All three signal quality parameters are shown in
Figure 16
for the non-
AGTL+ signal group.
