Pass/Fail Limit (Specification) Descriptions
37. TXA Signaling Tone Frequency (kHz)
37. TXA Signaling Tone Frequency (kHz)
This sets the pass/fail limits for the signaling tone’s frequency accuracy.
Upper and lower limits must be entered in Hz.
Pass/fail limits are determined by using any applicable standard such
as:
EIA/TIA Standard: Signaling Tone (ST)
Example
If you desire that the Signaling Tone frequency should be 10 kHz ±1 Hz,
enter 9.999 as the Lower Limit and 10.001 as the Upper Limit.
